GEOG1110 Online Lab Exercise 1 The Geographic Grid System Time Airphoto interpretation Instructions: 1. Complete all questions 2. Use the accompanying notes, your text and the Internet as a reference. 3. Turn in your completed lab to the drop box marked “Lab 1”. Note: You may work with other students, but all answers must be in your own words. If a classmate explains an answer to you, be sure to rewrite the answer in your own words. If you cannot do this, then you don’t understand the material well enough to properly answer the question yet. GEOG 1110 EARTH SCIENCE: Weather and Climate Source: http://geographyworldonline.com/tutorial/ “Imagine a Single Dot on a Table Tennis Ball. How Would You Describe Its Location?” It would be quite difficult. The same is true of locations on the Earth’s surface. Geographers have solved this problem by creating latitude lines and longitude lines. I. What is Latitude and Longitude? The Geographic gird of parallels and meridians is an artifact, or cultural thing, created by humans as a concept originating in the brain. Does this mean that the geographic grid shouldn’t be in include in physical geography? Latitude lines are imaginary lines on the earth’s surface. They run east and west around the globe and tell you your distance north or south of the Equator. Think of latitude like the rungs of a ladder (ladder sounds a lot like latitude). Latitude lines run east and west, but they tell how far up (north) you can go or how far down (south) you can go. Longitude lines are imaginary lines on the earth’s surface that run from pole to pole around the globe and tell you your distance east or west from the Prime Meridian. When you think of longitude, think of long, tall telephone poles (because longitude lines run from pole to pole). Longitude lines run north and south, but they tell how far east you can go or how far west you can go. To find a longitude line such as 40 degrees east longitude, you must do three things: 1. Go to your starting line (the Prime Meridian). 2. Determine which direction you must go (east or west). 3. Determine the distance in degrees you must go (40). This will give the location of one of your second street. If you find the intersection of these two imaginary streets, you have found the exact (absolute) location of a particular place on the earth's surface (shown by the red “X” on the map below. Important: The Equator is neither North nor South of the starting line, so it is simply 0º latitude (no direction needed). The Prime Meridian would be 0º longitude (no direction needed). Notice this on the two diagrams. IV. Lat/Long Exercises 1.Mapping question Match the locations A-E indicated on the map above, to the geographic coordinates below: 20oN, 160oW_ __ 20oN, 160oE _ __ 40oN, 0o _ __ 20oS, 160oW _ __ 40oS, 0o _ ___ 2.Using Google Maps, Google Earth, or an atlas, find each of the following cities and give the latitude and longitude coordinates for each (to the nearest half-degree). I have done the first for you. City Latitude Longitude Johnson City, TN, USA 36.5 oN 82.5 oW Recife, Brazil Falkland Islands Philadelphia, PN Mombasa, Kenya Milan, Italy 3.The following list gives the approximate attitude and longitude for five cities. Plot (with a circle) and LABEL (name) the approximate positions of these cities on the map provided on the following page. There are several ways to do this: A B C D E i) Use the drawing tools in your word processing software ii) Copy the map to Paint (found under Accessories in your Windows program list) and use the tools in Paint to label the map iii) Print out the map and label it by hand, then scan it, or snap a photo of it, saving the image as a .jpg file, which you can then import into this lab using insert>picture. EXAMPLE: see the following page for: Mumbai, India 19° N, 73° E a) Brisbane, Australia 27.5° S, 153° E b) Singapore, Singapore 1.5° N, 104° E c) Acera, Ghana 6° N, 0° d) Kharkiv, Ukraine 50° N, 36.5° E e) Chiclayo, Equador 0° , 80° W V Time and Time Zones M um ba i In di a
