Cubangbang's 6th Ch. 3 Natural Resources Stack #160784
| Question | Answer |
|---|---|
| Renewable energy; these can be replaced by natural means in a relatively short amount of time. | geothermal, hydroelectric, wind, solar |
| Nonrenewable resources; cannot be replaced easily | coal, natural gas, uranium, petroleum, |
| Materials available on earth for our use; provided by God | natural resources |
| Fossil fuels; formed when remains of plants and animals are buried quickly; provide most of the energy we use | fossil fuels |
| liquid form of fossil fuel | petroleum |
| oil pumped from wells come in this form | crude oil |
| a factory that separates crude oil into different products | refinery |
| solid substances naturally found in the earth's surface; often contains ores; it has never been a living organism | mineral |
| concentrated areas of specific minerals | vein |
| a mineral used in nuclear reactors | uranium |
| Problems that occurs as a result of using fossil fuels | air pollution, oil spills, production of soot and sulfur gases |
| Uses heat to produce steam; an advantage is that plants are inexpensive to build and operate | geothermal energy |
| Disadvantages of wind and solar energy | Requires large land areas |
| Advantages of wind energy | Does not cause pollution, Requires little maintenance |
| Soft & shapeable metals; example is gold | malleable |
| process of removing dross from ores | smelting |
| Ways to conserve soil (an important natural resource) | let fields lie fallow (resting), rotate crops, plant ground cover crops (low-growing crops that lessen erosion in unused fields), use contour plowing (method that keeps water from washing soil away) |
| Water cycle | precipitation, transpiration, evaporation, condensation |
| All of the earth's water | Hydrosphere |
| The layer of sand, gravel, or bedrock that holds and moves ground water (water stored beneath the surface of the earth) | aquifer |
| a floating ice sheet; very thick and forms from fresh water and covers land | ice shelf |
| forms when sea water freezes; relatively thin and forms from salt water and has no land under it | sea ice |
| 3 ways the ocean provides resources | oceans influence climates, part of the water cycle, part of the carbon dioxide-oxygen cycle |
