Name: __________________________________Date: _____________________________ Period: ____ Environmental Changes Test Review Key Define the following vocabulary terms below. Review your notes (44-47), labs and worksheets for this unit as well. o Weathering- breaking down of rock, soil, and minerals through contact with the earth o Erosion- a type of weathering in which surface soil and rock are worn away by wind, water, and glaciers o Deposition- soil, rock, or sediments are added to a land form or land mass o Condensation- water vapor collects in clouds. As clouds cool the water vapor condenses into water drops o Precipitation- water falls to the earth from clouds- mainly as rain, but sometimes as snow, sleet, or hail o Transpiration- process by which plants lose water out of their leaves; gives evaporation a bit of a hand in getting the water vapor back up into the air o Evaporation- process where heat energy from the sun causes water in puddles, streams, rivers, seas, or lakes to change from a liquid to a water vapor o Watershed- an area of land from which all runoff drains or "sheds" to the same river, lake, or other body of water o Water Table- underground depth at which point the ground is totally saturated with water o Ground Water- flows underground as springs or underground rivers, stored in an aquifer o Surface Water- water on the surface of the Earth o Runoff- water travels downhill and enters into rivers and lakes o Aquifer- a body of saturated rock or sediment through which water can move easily Name: __________________________________Date: _____________________________ Period: ____ o Succession- series of predictable changes that occur in a community over time o Primary Succession- begins in area WITHOUT soil, usually after a natural disaster such as volcanoes, landslides and flooding. Begins with a pioneer species, that doesn’t need soil, like lichen. Review steps in notes. o Secondary Succession- shorter succession (skips step 1), begins in an area WITH soil (remember SS); typically after a forest fire or harvest o Pioneer species- first organism to live in a new ecosystem; starts succession o Climax community- a stable group or plants and animals that is the END result of succession process; high levels of biodiversity exist and it is undisturbed by humans o Biodiversity- high level of variety among organisms o Eutrophication- process of body of water becoming rich in nutrients Complete the table for each energy source listed. List at least two pros and cons for each energy source. ENERGY SOURCE RENEWABLE OR NONRENEWABLE? PROS CONS Petroleum/Oil NONRENEWABLE • • • Considered to be highly efficient Widely used Delivery system already exists *SAME FOR ALL FOSSIL FUELS* • • • Non-renewable Emits pollutants into the air when burned Explosive and potentially dangerous *SAME FOR ALL FOSSIL FUELS* Natural Gas NONRENEWABLE Coal NONRENEWABLE Nuclear NONRENEWABLE • • Low greenhouse gas levels Large power-generating capacity • • • • Non-renewable High construction cost High risks in an accident Not easy or safe to ship Name: __________________________________Date: _____________________________ Period: ____ Solar Wind RENEWABLE & INEXHAUSTIBLE RENEWABLE & INEXHAUSTIBLE • Very little air pollution because it is not burned • • • Renewable Non-polluting Low maintenance • • • Intermittent Expensive Produce low grade energy • • • Clean Energy Renewable Power essentially free once infrastructure is paid for • • Inconsistent Wind from turbines and land needed make them only good in rural areas Wildlife fatalities • Water (Hydroelectric) RENEWABLE & INEXHAUSTIBLE • • • Little to no pollution Renewable Little cost after building dam • • • Building the power station is VERY expensive Flooding disrupts the ecosystem Dams prevent fish from swimming upstream What is the order of the natural processes that change the earth’s surface? Weathering Erosion Deposition Understand how humans impact the world around us- including the watersheds and ecosystems (you can find this information in Anthropogenic Changes Notes) List the 3 R’s of conservation (and understand their importance!)- Reduce, Reuse and Recycle
