3. Leaching: Downward movement of minerals and nutrients in the soil Lots of Rain Lots of Leaching Bad soil for farming Moderate Rain Moderate Leaching Good crop soil Irrigation: Artificially supplying water to land Soil Definitions:

5. Yes Is Soil a Renewable Resource?

6. Problem: Erosion from farming Conserving Soil:

7. Solution: Plow less Contour Plowing: plowing across a hill, rather than up and down it

9. Problem: Soil Exhaustion: almost all or all nutrients from the soil are gone Conserving Soil:

10. Solution: Fertilizer Crop Rotation: plant different crops in alternating years

11. Problem: Soil Salinization: soil becomes too salty for plant growth (usually goes with irrigation) Conserving Soil:

12. Solution: Effective drainage Irrigation methods that use less water

13. Habitats for animals, produce oxygen, wood, food, medicines, oils and rubber

14. Yes Are Forests a Renewable Resource?

15. Problem: Deforestation: destruction or loss of forests from logging, clearing for farm/ranchland, wood for fuel Conserving Forests:

17. Solution: Reforestation: planting new trees where old ones have been cut

18. One problem with reforestation is that although the trees are being replaced, you have lost the ecological diversity of the old growth forest

20. Yes Is Air a Renewable Resource?

21. Problem: Air Pollution Acid Rain: polluted rain that can damage trees and kill fish Ozone Layer: layer of the atmosphere that absorbs harmful UV rays Pollution destroys this layer and leads to an increase in skin cancer Conserving Air:

24. Solution: Careful use of chemicals in the environment

26. Aquifer: rock layers where ground water is plentiful Fossil Water: aquifer water that is not replenished by rain Water Definitions:

27. Yes Is Water a Renewable Resource?

28. Problem: Maintaining a clean water supply Solution: limit chemical use Prevent pollution of groundwater Problem: Depletion of water supply Solution: Careful use of fresh water Conserving Water:

30. Mineral: solid substance that comes out of the ground Ore: mineral-bearing rock Mineral Definitions:

31. No Are Minerals a Renewable Resource?

32. Problem: Running out Solution: Recycle minerals Conserving Minerals:

33. Problem: Destruction of environment through mining Solution: Enact and enforce environmental regulations Conserving Minerals:

36. Fossil Fuels: fuels formed by the remains of ancient plants and animals. COAL, NATURAL GAS, PETROLEUM(oil) Uranium: radioactive material used to create energy at nuclear power plants Energy Definitions:

38. Hydroelectric Power: electricity produced by moving water

39. Wind Power

40. Geothermal Energy: heat of the Earth’s interior used to create electricity

41. Solar Energy

42. Fossil Fuels NO Uranium Hydroelectric Power YES Wind Power Geothermal Energy Solar Energy Is Energy a Renewable Resource?

43. Problem: Fossil Fuels = pollution in the air (greenhouse gases) Problem: Uranium = dangerous waste Problem: Renewable Energy = costly Solution: better development of renewable and cleaner energy resources Conserving Energy:
