Geography – Nature & Perspectives Sequent occupance: The notion that successive societies leave their cultural imprints on a place, each contributing to the cumulative cultural landscape. This is an important concept in geography because it symbolizes how humans interact with their surroundings. Cultural landscape: Fashioning of a natural landscape by a cultural group. This is the essence of how humans interact with nature. Arithmetic density: The total number of people divided by the total land area. This is what most people think of as density; how many people per area of land. Physiological density: The number of people per unit of area of arable land, which is land suitable for agriculture. This is important because it relates to how much land is being used by how many people. Hearth: The region from which innovative ideas originate. This relates to the important concept of the spreading of ideas from one area to another (diffusion). Diffusion: The process of spread of a feature or trend from one place to another over time. Relocation diffusion: The spread of an idea through physical movement of people from one place to another. Ex: spread of AIDS from New York, California, & Florida. Expansion diffusion: The spread of a feature from one place to another in a snowballing process. This can happen in 3 ways: -Hierarchical diffusion: The spread of an idea from persons or nodes of authority or power to other persons or places (Ex: hip-hop/rap music) -Contagious diffusion: The rapid, widespread diffusion of a characteristic throughout the population. (Ex: ideas placed on the internet) -Stimulus diffusion: the spread of an underlying principle, even though a characteristic itself apparently fails to diffuse. (Ex: PC & Apple competition, p40) Absolute distance: Exact measurement of the physical space between two places. Relative distance: Approximate measurement of the physical space between two places. Distribution: The arrangement of something across Earth’s surface. Environmental determinism: A 19th- and early 20th-century approach to the study of geography that argued that the general laws sought by human geographers could be found in the physical sciences. Geography was therefore the study o f how the physical environment caused human activities. Absolute location: Position on Earth’s surface using the coordinate system of longitude (that runs from North to South Pole) and latitude (that runs parallel to the equator). Relative location: Position on Earth’s surface relative to other features. (Ex: My house is west of 394). Site: The physical character of place; what is found at the location and why it is significant (For more on Site & Situation, see p.16). Situation: The location of a place relative to other places. (For more on Site & Situation, see p.16). AP Human Geography – Vocabulary Lists Space Time Compression- The reduction in the time it takes to diffuse something to a distant place, as a result of improved communications and transportation system. Friction of Distance- is based on the notion that distance usually requires some amount of effort, money, and/or energy to overcome. Because of this "friction," spatial interactions will tend to take place more often over shorter distances; quantity of interaction will decline with distance. Distance Decay- The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin. Typically, the farther away one group is from another, the less likely the two groups are to interact. (Electronic devices such as the internet and e-mail have aided in eliminating barriers to interaction between people who are far from each other. Networks- defined by Manuel Castells as a set of interconnected nodes without a center. Connectivity- The relationships among people and objects across the barrier of space. Geographers are concerned with the various means by which connections occur. Accessibility- The degree of ease with which it is possible to reach certain location from other locations. Accessibility varies from place to place and can be measured. Space- Refers to the physical gap or interval between two objects. Spatial Distribution- Physical location of geographic phenomena across SPACE Size- Is the estimation or determination of extent. Scale- Representation of a real-world phenomenon at a certain level of reduction or generalization. In cartography, the ratio of map distance to ground distance, indicated on a map as a bar graph, representative fraction, and/or verbal statement. Formal Region- (uniform) or homogenous region is an area within which everyone shares in common one or mare distinctive characteristics. The shared feature could be a cultural value such as a common language, or an environmental climate. Functional Region- (nodal region) Area organized around a node or focal point. The characteristic chosen to define a functional region dominates at a central focus or node and diminishes in importance outward. This region is tied to the central point by transportation or communication systems or by economic or functional associations. Vernacular Region- (Perceptual Region) is a place that people believe exists as a part of their cultural identity. Such regions emerge from peoples informal sense of place rather than from scientific models developed through geographic thought. (Often identified using a mental map- which is an internal representation of a portion of Earths surface) Possibilism- The physical environment may limit some human actions, but people have the ability to adjust to their environment. Natural Landscape- (xxx) Pattern- A common property of distribution, which is the geometric arrangement of objects in space. Some features are organized in a geometric pattern, whereas others are distributed irregularly. Geographers observe that many objects form a linear distribution, such as the arrangement of houses along a street or stations along a subway line. Place Name- Often referred to as a places toponym (the name given to a place on Earth. Population projection- predicts the future population of an area or the world. Helps predict future problems with population such as overpopulation or under population of a certain race or ethnicity. Population pyramid- population displayed by age and gender on a bar graph Shape is determined primarily by crude birth rate. Shows age distribution and sex ratio. Rate of natural increase- the percentage by which a population grows in a year. CBR-CDR = NIR Excludes migration Affects the population and a country’s or area’s ability to support that population. S-curve- traces the cyclical movement upwards and downwards in a graph. So named for its shape as the letter "s" Relates to growth and decline in the natural increase. Sex ratio- the number of males per hundred females in the population Depends on birth and death rates, immigration. Men have higher death rates but also higher birth rates. Immigration usually means more males because they can make the journey. Standard of living- refers to the quality and quantity of goods and services available to people and the way they are distributed within a population Higher standards of living are found in MDC’s rather than LDC’s. Can help trace development. Sustainability- providing the best outcomes for human and natural environments both in the present and for the future Relates to development that meets today’s needs without compromising the ability of future generations to meet their own needs. Underpopulation- it is the opposition to overpopulation and refers to a sharp drop or decrease in a region’s population Unlike overpopulation, it does not refer to resources but to having enough people to support the local economic system. If there are not enough tax payers, then the area cannot continue. Zero population growth- when the crude birth rate equals the crude death rate and the natural increase rate approaches zero. Often applied to countries in stage 4 of the demographic transition model. Activity space- space allotted for a certain industry or activity Can apply to an area within a city or surrounding a central place. Chain migration- when one family member migrates to a new country and the rest of the family follows shortly after Mostly seen from Mexico to the United States when guest workers set up homes and make money for their family to follow them. Cyclic movement- trends in migration and other processes that have a clear cycle Distance Decay- When contact between two groups diminishes because of the distance between them. Forced Migration- People removed from there countries and forced to live in other countries because of war, natural disaster, and government. ( Gravity Model- Predicts that the optimal location of a service is directly related to the number of people in the area and inversely related to the distance people must travel to access it. Internal Migration- Permanent movement within a particular country. Intervening Opportunity- An environmental or cultural feature of the landscape that helps migration. Migration Patterns: Intercontinental- Permanent movement from one country to a different country on the same continent. Interregional- Permanent movement from one region of the country to another. Rural-Urban- Permanent movement from suburbs and rural area to the urban city area. Migratory Movement- Periodic Movement- Personal Space- Place Utility- Push-Pull Factors- Factors that induce people to leave old residence and move to new locations. Refugee- People forced to migrate from their home country and cannot return for fear of persecution because of their race, religion, nationality, membership in social group, or political opinion. Space-Time Prism- Step Migration- Transhumance- Seasonal migration of live stock between mountains and lowland pasture areas. Transmigration- Voluntary- III. Cultural Patterns & Processes Acculturation: Process of adopting only certain customs that will be to their advantage Assimilation: Process of less dominant cultures losing their culture to a more dominant culture Cultural Adaptation: Cultural core/periphery pattern: The core-periphery idea that the core houses main economic power of region and the outlying region or periphery houses lesser economic ties Cultural Ecology: The geographic study of human environmental relationships Cultural Identity: Ones belief in belonging to a group or certain cultural aspect Cultural Landscape: The visible imprint of human activity on the landscape Cultural Realm: Culture: The body of customary beliefs, social forms, and material traits that together constitute a group of people’s distinct tradition. Culture Region: Formal (Uniform): An area in which everyone shares in one or more distinctive characteristics Core-Center of economic activity Periphery-Outlying region of economic activity Functional (Nodal): Region organized at a node or focal point Vernacular (perceptual-regional self-awareness): A place that people believe exists as part of their cultural identity Diffusion Types: Expansion-The spread of one feature from one place to another in a snowballing process Hierarchical-The spread of an idea from persons or nodes of authority or power to other persons or places Contagious-The rapid widespread diffusion of a characteristic throughout the population Stimulus-The spread of an underlying principle when the characteristic fails to diffuse Relocation-The spread of an idea through physical movement of people from one place to another Innovation Adoption: Study of how why and at what rate new technology spreads throughout a culture Maladaptive diffusion: Diffusion of a process with negative side effects or What works well in one region may not in another Sequence Occupancy: Refers to such cultural succession and its lasting imprint proposed by Derwent Whittlesey Religion-the faithfulness to codified beliefs and rituals that generally involve a faith in a spiritual nature. This is important to HG because man wars have been fought over it. Animism: Belief that objects, such as plants and stones, or natural events, like thunderstorms and earthquakes, have a discrete spirit and life. This is important to Human Geography because a lot of cultures around the world believe in Animism. Buddhism: The third of the world’s major universalizing religions. It has 365 million adherents especially in China and Southeast Asia. It is important because a large percent of the earth’s population follow Buddhism beliefs. Cargo Cult Pilgrimage- Cargo Cult’s believe western goods have been traded to them by ancestral spirits. It takes place in Melanesia and is important go HG because it’s a big religious movement by a large number of people. IV. Political Organization of Space Annexation: Incorporation of a territory into another geo-political entity. Antarctica: Southernmost continent in the world. It has no permanent residents and doesn't belong to any country. Apartheid: Afrikaans for apartness, it was the segregation of blacks in South Africa from 1948 to 1994. It was created to keep the white minority in power and allow them to have almost total control over the black majority. Balkanization: The political term used when referring to the fragmentation or breakup of a region or country into smaller regions or countries. The term comes from the Balkan wars, where the country of Yugoslavia was broken up in to six countries between 1989 and 1992. It was the effect of the Balkan wars. Border Landscape: There are two types, exclusionary and inclusionary. Exclusionary is meant to keep people out, such as the border between the U.S. and Mexico. Inclusionary is meant to facilitate trade and movement, such as the U.S.-Canada border. Boundary disputes: Conflicts over the location, size, and extent of borders between nations. There is conflict over where exactly the border is between the U.S. and Mexico, especially along the Rio Grande because the river has changed course and moved, and it is the traditional border. Boundary origin: Boundaries often originated from old tribal lands and lands won in war. They were meant to establish claims to land and were often smaller historically. Boundary process: The process of creating boundaries. Boundary type: Many boundaries are natural boundaries, formed by rivers, mountains, etc. There are also political boundaries. These are often formed through war and compromise in treaties and agreements. In countries often form cultural boundaries that used to belong to a groups cultural homeland. However, countries in Africa, the Middle East and elsewhere aren't arranged by culture but politics, and Western countries turned their former colonies into nations without respect for culture. Buffer state: A country lying between two more powerful countries that are hostile to each other. An example is Mongolia, which serves as a buffer between Russia and China. Capital: Principle city in a state or country. The best place to locate a capital is at the center of a country, so it is a somewhat equal distance from all parts of the country. Centrifugal: Religious, political, economic, conflict, etc. that causes disunity in a state. Centripetal: An attitude that unifies people and enhances support for the state. City-state: A region controlled by a city and that has sovereignty. They were more common in the middle ages and Renaissance in Europe. Colonialism: The attempt by a country to establish settlements and impose political and economic control and principles. It was a big thing in the 17th through 20th century for countries in Europe to take areas around the world and make them into colonies. Confederation: association of sovereign states by a treaty or agreement. It deals with issues such as defense, foreign affairs, trade, and a common currency. Conference of Berlin: Regulated trade and colonization in Africa. It formalized the scramble to gain colonies in Africa and set up boundaries for each country’s colonies. Core/periphery: Core countries have high levels of development, a capacity at innovation and a convergence of trade flows. Periphery countries usually have less development and are poorer countries. Decolonization: Decolonization is the movement of American/European colonies gaining independence. Some were peaceful struggles while others became violent. Devolution: Devolution is the both the decentralization of a government from a unitary to a federal system or a fracturing of a government like Balkanization. Domino theory: Domino theory is the idea that if one land in a region came under the influence of Communists, then more would follow in a domino effect. The domino theory was used by successive United States administrations during the Cold War, to justify American intervention around the world. Exclusive Economic Zone: An Exclusive Economic Zone (EEZ) is a sea zone over which a state has special rights over the exploration and use of marine resources. The country that controls the EEZ has rights to the fishing, whaling, etc., as well as the raw material resources. Electoral regions: Electoral regions are the different voting districts that make up local, state, and national regions. Enclave/exclave: An enclave is a country or part of a country mostly surrounded by the territory of another country or wholly lying within the boundaries of another country (Lesotho). An exclave is a country which is geographically separated from the main part by surrounding alien territory (Azerbaijan). Ethnic conflict: An ethnic conflict is a war between ethnic groups often as a result of ethnic nationalism or fight over natural resources. Ethnic conflict often includes genocide. It can also be caused by boundary disputes. European Union: The European Union (EU) is a supranational and intergovernmental union of 27 democratic member states of Europe. The EU's activities cover most areas of public policy, from economic policy to foreign affairs, defense, agriculture and trade. The European Union is the largest political and economic entity on the European continent, with around 500 million people and an estimated GDP of US$13.4 trillion. Federal: Federalism is a political philosophy in which a group or body of members are bound together with a governing representative head. Federalism is the system in which the power to govern is shared between the national & state governments. Forward capital: A forward capital is a symbolically relocated capital city usually because of either economic or strategic reasons. A forward capital is sometimes used to integrate outlying parts of a country into the state. An example would be Brasília. Frontier: A frontier is a zone where no state exercises complete political control. It is usually uninhabited or sparsely inhabited. It separates countries where a boundary cannot be found. A current example can be found between Saudi Arabia and Yemen. Geopolitics: Geopolitics is the study that analyzes geography, history and social science with reference to international politics. It examines the political and strategic significance of geography, where geography is defined in terms of the location, size, and resources of places. Gerrymander: Gerrymandering is the process of redrawing legislative boundaries for the purpose of benefiting the political party in power. The process is usually used to turn “too close to call” states into a party’s favor. Global commons: Global commons is that which no one person or state may own or control and which is central to life. A global common contains an infinite potential with regard to the understanding and advancement of the biology and society of all life. (Forests, oceans, land mass and cultural identity) Heartland/rimland: Heartland is the central region of a country or continent; especially a region that is important to a country or to a culture. Rimland is the maritime fringe of a country or continent. Immigrant state: An immigrant state is a type of receiving state which is the target of many immigrants. Immigrant states are popular because of their economy, political freedom, and opportunity. One example would be the USA. V. Agricultural & Rural Land Use Adaptive strategies: Agrarian: People or societies that are farmers therefore promote agricultural interest ext. -Where agrarian people and societies are located is not generally near cities ext. but these types of people are essential to the way that we live and our ability to live in cities. Agribusiness: Commercial agriculture characterized by integration of different steps in the food-processing industry, usually through ownership by large corporations. - It influences how things are grown and what people eat Agricultural Industrialization: The use of machinery in agriculture, like tractors ext. - Makes it a lot faster for farmers to yield crop Agricultural landscape: The land that we farm on and what we choose to put were on our fields. - Effects how much yield one gets from their plants. Agricultural location model: Agricultural Origins: Through time nomadic people noticed the growing of plants in a cycle and began to domesticate them and use for there own use. Carl Sauer points out vegetative planting and seed agriculture as the original forms. He also points out that vegetative planting likely was originated in SE Asia and seed agriculture originated in W. India, N. China and Ethiopia. -Without the development of agriculture we would still have a relatively small and likely uneducated population Agriculture: The deliberate effort to modify a portion of Earth’s surface through the cultivation of crops and the raising of livestock for subsistence or economic gain. -It has influenced the growth of areas and human society Animal Domestication: Domestication of animals for selling or using byproducts. -Helped us obtain meat with out having to go out and kill our food right before dinner. Aquaculture: The cultivation of aquatic organisms especially for food -Allowed us to use the sea and its abundant sources of food for our benefit Biorevolution: The revolution of biotechnology and the use of it in societies. - See reasoning for below term Biotechnology: Using living organisms in a useful way to produce commercial products like pest resistant crops. -Has helped the farmers grow a more bountiful harvest through the using of pesticides ext. Collective farm: Commercial Agriculture (intensive, extensive): Agriculture undertaken primarily to generate products for sale off the farm. -Allowed people to move away from farms- fueled industrial revolution Core/Periphery: The areas in the world that include MDCs are called the core and the area of the world that contains the LDCs is referred to as the periphery. Crop Rotation: The practice of rotating use of different fields from crop to crop each year, to avoid exhausting the soil. -Nucleated – a number of families live in close proximity to each other, with fields surrounding the collection of houses and farm buildings. -Building Material – houses and buildings are typically built from materials that are abundant in the area. -Village Form – Sauer, Carl O. – defined cultural landscape, as an area fashioned from nature by a cultural group. A combination of cultural features such as language and religion; economic features such as agriculture and industry; and physical features such as climate and vegetation. “Culture is the agent, the natural area is the medium, the cultural landscape is the result.” Second Agricultural Revolution – Precursor to Industrial Revolution in the 19th century, that allowed a shift in work force beyond subsistence farming to allow labor to work in factories. Started in United Kingdom, Netherlands, and Denmark, especially with the Enclosure Act, which consolidated land in Great Britain. Potatoes and corn diffused from America’s to Europe, and other resources followed from colonial possessions to Europe. Specialization – Third level of cities (behind World Cities, and Command and Control Centers), offer a narrow and highly specialized variety of services. Typically specialize in management, research and development of a specific industry (motor vehicles in Detroit), or are centers of government and education, notably state capitals that also have a major university (Albany, Lansing, Madison, or Raleigh-Durham). Staple Grains – Maize, wheat, and rice are the most produced grains produced world wide, accounting for 87% of all grains and 43% of all food. Maize staple food of North America, South American, Africa, and livestock worldwide, wheat is primary in temperate regions, and rice in tropical regions. Suitcase Farm –Individuals who live in urban areas a great distance from their land and drive to the country to care for their crops and livestock. This practice lends itself well to the growth of wheat. Allows families to continue their long relationships with the ancestral farm, but still enjoy the benefits of waged incomes in urban environments. Survey Patterns – -Long Lots (French) – Houses erected on narrow lots perpendicular along a river, so that each original settler had equal river access. -Metes and Bounds (English) – Uses physical features of the local geography, along with directions and distances, to define the boundaries of a particular piece of land. Metes refers to boundary defined by a measurement of a straight run, bounds refers to a more general boundary, such as a waterway, wall, public road, or existing building. Township-and-Range (U.S.A) – Survey’s used west of Ohio, after the purchase of the Louisiana Purchase. Land is divided into six-mile square blocks (township), which is then divided into one-mile square blocks (range). Ranges were then broken into smaller parcels to be sold or given to people to develop. Sustainable Yield – Ecological yield that can be extracted without reducing the base of capital itself, the surplus required to maintain nature’s services at the same or increasing level over time. Example, in fisheries the basic natural capital decreases with extraction, but productivity increases; so the sustainable yield is within the ranch that the natural capital together with production are able to provide satisfactory yield. Third Agricultural Revolution –‘Green Revolution’ Rapid diffusion of new agricultural techniques between 1970’s and 1980’s, especially new high-yield seeds and fertilizers. Has caused agricultural productivity at a global scale to increase faster than population growth. Mechanization – Farmers need tractors, irrigation pumps, and other machinery to make the most effective use of the new miracle seeds. Farmer’s in LDC’s cannot afford this machinery or the fuel to run the equipment, so governments must allocate funds to subsidizing the cost of seeds, fertilizers and machinery. Chemical Farming – Increased use of fertilizers with nitrogen, phosphorus, and potassium. The development of higher-yield crops has produced: a ‘miracle wheat seed” which is shorter and stiffer, less sensitive to variation in day length, responds better to fertilizers, and matures faster; a similar miracle rice seed, that was heartier and has increased yields; a high-yield corn seed is currently being developed. Food Manufacturing – the Green Revolution has increased production to avoid widespread famine. Allowing the world population to grow about four billion since stared, also allowing populations in developing nations to consume 25% more than before. This increase in diets is questioned by the content in diets; Asian farmers are eating more rice than fish and other vegetables because they can rely on rice to grow efficiently. ‘Tragedy of the Commons’ – social trap that involves a conflict over resources between interests and the common good. Transhumance –pastoral practice of seasonal migration of livestock between mountains and lowland pasture areas. Truck Farm – Commercial gardening and fruit farming, so named because truck was a Middle English word meaning bartering or the exchange of commodities. Predominant in Southeastern U.S.A, because of the long growing season and humid climate, accessibility to large markets of New York, Philadelphian, and Washington. Truck farms grow many of the fruits and vegetables that consumers demand in developed societies. Truck farms sell some of their product to fresh markets, but mostly to large processors for canning or freezing. Truck farms are highly efficient and large-scale operations that take full advantage of machines at every stage of the growing process. Von Thunen, Johann Heinrich – 1826, Northern Germany. When choosing an enterprise, a commercial farmer compares two costs; cost of the land versus the cost of transporting production to market. Identifies a crop that can be sold for more than the land cost, distance of land to market is critical because the cost of transporting varies by crop. Also found that specific crops were grown in varying rings around city. Market-oriented gardens and milk producers in first ring, because of expense of transportation and perishability. In the next rings wood lots used for construction and fuel, because it is a heavy industry with high transportation costs. Next rings are used for various crops or pasture, with the outermost ring devoted to animal grazing. Von Thunen’s theory disregards site or human factors. VI. Industrialization & Development Agricultural labor force is the number of people who work in agriculture. This is important because a large value indicates that the country is likely an LDC dependent on agriculture, while a small value indicates that there are fewer people working in agriculture, meaning that the agriculture is more efficient. Calorie consumption as a percentage of daily requirement is an important index of development. People in MDCs generally consume more than 130% of their daily requirements, but most people in LDCs barely get enough to sustain themselves. The problem is worst in Africa, where most people do not eat enough. The Core-periphery model describes the pattern of distribution of the MDCs and LDCs. When the earth is viewed from the North Pole, the MDCs are clustered near the center of the map while the LDCs are near the edges. Cultural Convergence is the change in culture that occurs as diffusion of ideas and technology increases. An example is the culture of LDCs becoming more like that of their former colonial power (an MDC). Dependency theory states that LDCs tend to have a higher dependency ratio, the ratio of the number of people under 15 or over 64 to the number in the labor force. Development is the improvement in material conditions of a place as a result of diffusion of technology and knowledge. This is important because it is a main goal for most of the planet’s regions and development will help solve many problems. Energy consumption is an index of development. MDCs tend to consume much more energy per capita than do LDCs. This will be important in the future because as LDCs begin to industrialize, there will be a great strain on the world’s energy supply. Foreign direct investment is investment in the economies of LDCs by transnational corporations based in MDCs. However, all countries are not recipients of this investment. Brazil, China and Mexico were the LDCs that received most of the investment. Gender is an important developmental factor. A great difference in development between the genders is found primarily in LDCs, especially in the Middle East. Differences exist primarily in income and in literacy rate. Gross domestic product is the total value of goods and services produced in a year in a given country. The value varies greatly between MDCs and LDCs and is one of the best indicators of development. Fast growth of GDP is a major goal of all countries. Gross national product is similar to GDP except that includes income that people earn abroad. The Human Development Index is an aggregate index of development, which takes into account economic, social and demographic factors, using GDP, literacy and education, and life expectancy. Levels of development that countries are classified into include MDCs (more developed countries) and LDCs (less developed countries). Measures of development are used to distinguish LDCs from MDCs. They include GDP, literacy rate, life expectancy, caloric intake, etc. Neocolonialism refers to the economic control that MDCs are sometimes believed to have over LDCs. Through organizations such as the IMF, the MDCs are able to dictate precisely what LDCs economic policies are, or are able to use their economic subsidies to put LDCs industries out of business. The Physical Quality of Life index is another development index. It is based on literacy rate, infant mortality rate, and life expectancy at age one. Purchasing power parity is an index of income related to GDP. Unlike GDP however, PPP takes into account price differences between countries. Usually goods in LDCs are priced lower, so this makes the difference between LDCs and MDCs less. W.W. Rostow developed the “Stages of Growth” model of economic development. Technology gap- The difference in technologies used and/or developed in two companies, countries, ethnic groups, etc., where one is more advanced than the other. - Important because it helps to explain the differences between MDCs and LDCs. Technology transfer- process by which existing knowledge, facilities, or capabilities developed under federal research and development funding are utilized to fulfill public and private needs - Important because it allows for knowledge to be utilized for various needs instead of being confined to a certain sector. Third World- countries in the developing world independent of their political status (developing countries) - Important because it is a classification to explain differences between the countries of the world. World Systems Theory- refers to perspective that seeks to explain the dynamics of the “capitalist world economy” as a “total social system” - Important because explains the power hierarchy in which powerful and wealthy "core" societies dominate and exploit weak and poor peripheral societies. Bid rent theory- refers to how the price and demand on land changes as the distance towards the CBD increases - Important because it provides an explanation as to the spatial distribution of urban areas. Assembly line production/Fordism- industrial arrangement of machines, equipment, and workers for continuous flow of work pieces in mass production operations, each movement of material is made as simple and short as possible - Important because it allowed for goods to be produced at a rate comparable to the demand for many of those products, made for more efficient manufacturing industries.
