Unit 3 Resources
Use your Textbook (Chap 4), Vocabulary, Notes, FRAMES, Unit Organizer, and this Study Guide to prepare for the TEST. Remember, your score depends on you knowing and understanding the content. Studying requires your time and concentration. Complete the following using your Unit 3 Materials.
|1. List all the fossil fuels.||Coal, Natural Gas, Petroleum
|2. List all the non-renewable resources.||Minerals, Coal, Natural Gas, Petroleum
|3. List all the renewable resources.||Biomass, water, soil, sunlight, air, tides|
|4. What is the main reason coal is used to produce electricity?||Cheap when compared to other choices.|
|5. What are the biggest problems with depending on fossil fuels?||Nonrenewable, causes pollution, adds carbon dioxide to atmosphere.|
|6. What are the environmental benefits gained by using renewable energy?||Fewer pollutants, fewer greenhouse gases (ex. carbon dioxide, carbon monoxide)|
|7. Which fuel has the least environmental impact on the Earth?||Solar energy|
|8. Why is it a bad idea to depend on wind power to generate electricity for a large city?||The source inconsistent.|
9. What is climate change?
|Change in temperature over a long period of time; related to burning of fossil fuels.|
|10. How does nuclear power help to slow climate change?||Does not generate carbon dioxide. Doesn’t contribute to climate change.|
|11. What is the main disadvantage of using nuclear as an energy resource?||Creates long-lasting waste (radioactive waste).|
|12. What is the main disadvantage of using coal as an energy resource?||Causes pollution when burned.|
|13. What is the main disadvantage of using solar/solar panels as an energy resource?||Only available during the day or through storage (cell).|
|14. What are the main disadvantages of using wind as an energy resource?||Occasionally available. Wind turbines obstruct views. Kills birds.|
|15. What is the one negative thing about using wind turbines on the peak of mountains?||Interferes with migratory birds.|
|16. What is the greatest environmental cost of hydroelectric power?||Destruction of free-running rivers and its ecosystem.|
|17. What is the source of Geothermal Energy?||Within the earth’s crust (volcano).|
|18. What is Geothermal Energy used for?||Space (building) heating and cooling, and hot water heaters.|
|19. What region or province in VA is best known for coal production?||Appalachian Highlands.|
|20. What natural resource makes the biggest contribution to VA’s economy?||Coal|
|21. What is coal used for?||Power plants à energy
|22. What is silica used for?||Electronics|
|23. What is gravel/crushed stone used for?||Road Construction|
|24. What is limestone used for?||Concrete|
|25. What is a largely untapped reusable energy source in VA?||Tidal energy|
|26. What is strip mining and what is one method to lessen the environmental impact?||Removal of top the top of a mountain to extract coal. Require that landscape and vegetation of mined land be restored.|
|27. What is (a) biomass and what are all the different kinds?||Burning former living plant material as fuel for energy. Ex. soybeans & corn, wood, grass-eating animal dung, peat blocks.|
|28. When looking at this graph, what can you conclude about energy consumption (=use)?||About 75% of consumption is a combination of fossil fuels.
|29. Historically, Midwest factories were responsible for high concentrations of local air pollutions. They raised the height of the smokestacks, which solved the local air pollution problem. (a) What happened to the pollutants and (b) what did it contribute to?||They were caught up in the wind and carried to the NE United States where they contributed to acid rain.|
|30. Which source of energy is thought to have the smallest ecological impact on Earth?||Solar Power Cells|
|31. What are the two most common organic sedimentary rocks?||Limestone & coal|
|32. When classifying rocks, they are classified as sedimentary, igneous, or metamorphic based on what?||Based on origin (where).|
|33. How are sedimentary rock layers always deposited?||Horizontally.|
|34. What kind of grain do igneous rocks have and why?||Coarse grain, intrusive…cools slowly.
Fine grain, extrusive…cools quickly.
|35. When looking at an igneous rock, what is the best evidence of the environment in which it was formed?||The texture which is actually the size of the grain/crystal.|
|36. (a) How are metamorphic rocks classified? (b) Which type has stripes or bands of color?||Foliated…with stripes/bands of color.
Non-foliated…without stripes/bands of color.
37. When figuring out the position of a point on a map the latitude gets larger going N and S of the Equator and the longitude get larger going east and west of the Prime Meridian.
|38. What is the formula for Density?||D=m/v|
|39. What are the steps of coal formation in order?||1. Ancient vegetation in swampy area
2. Vegetation dies & gets buried
3. Sedimentary layers continue to deposit on top of the dead vegetation
4. Heat and pressure caused by layers piling up change it into coal
40. The unit for mass is grams and the unit for volume is milliliters.
|41. If a rock sample is 24 grams, and its volume is 6 millimeters, its density is calculated as ___________.
