1. What is a natural resource?
    something in nature or a part of nature that we can use
  2. What are fossil fuels?
    remains of ancient life that we use for energy
  3. How can you help to conserve natural resources?
    • 1- use renewable resources
    • 2- conserve water
    • 3- walk, ride a bike, etc.
  4. List 3 non-renewable resources
    • 1- oil
    • 2- coal
    • 3- natural gas
  5. What causes acid precipitation?
    when air pollution from fossil fuels react with water in the atmosphere (destroys food chains)
  6. List 5 renewable resources?
    • 1- hydroelectric
    • 2- solar
    • 3- windpower
    • 4- nuclear
    • 5- geothermal
  7. List one advantage and one disadvantage for each renewable resource
    • 1- destrpys habitats
    • 2- expensive
    • 3- need lots of space
    • 4- dangerous
    • 5- have to live in a volcanically active place
  8. Describe the greenhouse effect
    Earths atmosphere traps some light & changes it to heat
  9. What gas is causing the greenhouse effect to become more intense
    carbon dioxide
  10. Most air pollution results from the..
    burning of fossil fuels
  11. The 3 "R"s of conservation are
    reduce, reuse, recycle
  12. Substances that provide energy as a result of a chemical change are called
  13. Energy coservation means
    reduce the amount of energy that you dont really need to use
  14. The % of energy that is actually used to perform work
  15. This fossil fuel are the remaints of ancient, decayed plants-tiny creatures-
    coal, oil
  16. In the US the most commonly used fossil fuel is
  17. .....still produces pollution, but is the cleanest burning fossil fuel
    natural gas
  18. another form of oil
  19. material that helps block the transfer of heat between into and out of a building is
  20. List 6 sources of indoor air pollution
    • 1- carbon monoxide
    • 2- pet dander
    • 3- second hand smoke
    • 4- dust mites
    • 5- bacteria
    • 6- cleaning products
    • 7- mold
    • 8- pesticides
    • 9- gas fumes
    • 10- dust
  21. a radioactive gas that is naturally produced by soil & rock
  22. 5 consequences of continued global warming are:
    • 1- melting ice caps
    • 2- stronger storms
    • 3- sea levels rise
    • 4- changes in rainfall
    • 5- species die out
  23. responsible for the depletion of the ozone layer
  24. ...odorless, colorless, poisonous gas produced by the...
    carbon monoxide, burning of fossil fuels
  25. water that collects between particles of soil and rock
  26. waste materials that are harmful to humans are called
    hazardous wastes
  27. why is the loss of ice at the poles a disturbing trend and what does it suggest for the future?
    more light is absorbed
  28. how could global warming trigger another ice age?
    melting water disrupts air and water currents
  29. if mountain glaciers were to disappearwhat consequences would that mean for 40% of the world
    no fresh water
  30. what is the relationship between carbon dioxide and global temperature?
    when one goes up so does the other
