TERM 1 Of the following, which are components of Earth's climate system? DEFINITION 1 Biosphere Atmosphere Cryosphere Geosphere hydrosphere (including the oceans) TERM 2 Of the following, which are examples of climate feedback loops? DEFINITION 2 heat uptake by the oceans the addition of water vapor into the atmosphere the presence of fine atmospheric particles called aerosols the shading effect from air pollution the role of clouds at different altitudes TERM 3 Of the following, which are useful as proxy data for understanding past climate changes? DEFINITION 3 tree-growth rings sea floor sediments annual layers of snow packed in glacial ice historical documents fossil pollen TERM 4 Of the following natural factors, which have caused past climate changes on Earth? DEFINITION 4 the movement of Earth's tectonic plates changes in solar energy volcanic eruptions variations in Earth's orbit TERM 5 The warming of Earth's surface and atmosphere is a natural process controlled by the greenhouse effect. It is also being altered by human emissions, a phenomenon that is often referred to as ___________. DEFINITION 5 the anthropogenic greenhouse load the enhanced greenhouse effect TERM 6 What are the main factors that contribute to the documented global rise in sea level? DEFINITION 6 thermal expansion of ocean water as it warms an increase in the amount of water in the ocean from the melting of ice on land TERM 7 Of the following, which ocean changes are predicted to result from global warming? DEFINITION 7 increased transmission distance of sound in the sea increase in ocean stratification and the development of a stronger thermocline migration of marine organisms into deeper waters and toward the poles lower amounts of dissolved oxygen in seawater TERM 8 Global engineering (geoengineering) proposals to reduce Earth's greenhouse effect include ____________________. DEFINITION 8 removing human-caused greenhouse gases from the atmosphere and disposing of them somewhere else. reducing the amount of sunlight reaching Earth. TERM 9 Of the following statements about the iron hypothesis, which is/are true? DEFINITION 9 -Oceanographer John Martin proposed fertilizing the ocean with iron to increase its productivity. -Adding iron to the ocean might cause an ecological disaster in the ocean. -Adding iron to the ocean increased phytoplankton productivity up to 30 times. - Adding iron to the ocean removes carbon dioxide from the atmosphere, which helps reduce global warming. TERM 10 Of the following statements about the greenhouse effect and global warming, which is/are true? DEFINITION 10 Global warming will likely result in a rise in sea level due to melting glaciers and thermal expansion of warm ocean waters. Global warming will likely result in more intense tropical storms. Global warming will likely result in more prolonged droughts. Global warming will likely result in more rainfall.
