Across
  1. 4. natural resources that people use for energy
  2. 5. all of the Earth’s air
  3. 9. the process by which water seeps through the ground and enters an aquifer
  4. 11. heat energy that comes from deep within Earth
  5. 13. a natural resource that cannot be replaced as quickly as it is used
  6. 17. a situation that involves giving something up in return for gaining something else
  7. 21. a natural resource that is only renewable if it is not used too quickly
  8. 22. all of the Earth’s rocks, minerals, and soil
  9. 23. rocks that allow liquid or gas to pass into and through them
  10. 24. resources obtained from the natural world that are used by humans for survival and to improve the quality of their lives
  11. 25. the loss of healthy soil and expansion of deserts, typically caused by soil pollution, repeated growth of nutrient-depleting crops in the same fields, strip mining, overgrazing cattle, clearing forestland, etc.
  12. 26. fuel made from biomass (plant matter, such as wood or crop waste)
  13. 27. a mineral deposit that has a high enough concentration of a specific mineral to be worth mining and processing
  14. 29. plant matter that can be burned for heat or used to make other fuels
  15. 30. the concentration of resources in specific places because of the processes by which they form
  16. 31. a natural resource that can be replaced at the same rate it is used, or faster
  17. 32. a result that follows naturally from the actions of a person or group; can be positive or negative; can be short-term or long-term
Down
  1. 1. rocks that do not allow water or other fluids to flow through them; prevent groundwater from entering or leaving aquifers
  2. 2. all of the Earth’s water
  3. 3. resources formed from the buried remains of plants and animals; coal, petroleum/oil, and natural gas
  4. 6. energy created from the atomic decay of an element, such as Uranium
  5. 7. a natural resource whose supply is not affected by human activity; can’t be used up
  6. 8. die out completely
  7. 10. all of the the Earth’s living things
  8. 12. electric energy generated when water flows through a hydroelectric dam to turn the blades of a turbine
  9. 14. also called REEs, these are elements found deep within Earth that are difficult and costly to mine; widely used in electronics, batteries, magnets, etc.
  10. 15. electrical energy generated when a windmill uses moving air to turn the blades of a turbine
  11. 16. the nutrient-rich layer of soil at the surface, formed as organic matter is added from decomposing organisms
  12. 18. natural resources humans use to make objects or to eat as food
  13. 19. energy from the sun is absorbed and converted to electrical energy
  14. 20. loose mixture of sediment, organic material, water, and air
  15. 28. layers of permeable rock beneath the surface where groundwater flows or is stored
