4th Grade Ch 10 Lesson 2 How Are Resources Used For Energy

  1. 1. Ch. 10 Lesson 2 How are resources used for energy?
  2. 2. Uses of Sun’s energy: <ul><li>plants use it for photosynthesis </li></ul><ul><li>solar energy transferred from plants  animals thru. food chains </li></ul>
  3. 3. Uses of Sun’s energy: <ul><li>solar cells/panels collect energy </li></ul><ul><li>sunlight warms Earth </li></ul>
  4. 4. Other renewable energy sources: <ul><li>wind energy </li></ul>
  5. 5. Other renewable energy sources: <ul><li>energy from flowing water </li></ul>
  6. 6. nonrenewable energy resources <ul><li>supplies that exist in limited amounts or are used much faster than can be replaced in nature </li></ul>
  7. 7. ore <ul><li>rock rich in minerals that can be removed from Earth </li></ul>
  8. 8. fossil fuels <ul><li>made from organisms that lived long ago </li></ul><ul><li>examples: </li></ul><ul><li>coal </li></ul><ul><li>natural gas </li></ul><ul><li>oil (petroleum) </li></ul>
  9. 9. coal <ul><li>formed from ancient plants </li></ul>
  10. 10. how coal is formed: <ul><li>millions of yrs. ago, dead plants were buried in swamps </li></ul><ul><li>layers of dead plants hardened & formed sedimentary rock by heat & pressure </li></ul><ul><li>chemicals stored in these organisms became coal </li></ul>
  11. 11. when coal is burned, releases energy from sun collected by ancient plants
  12. 12. impact of fossil fuels: <ul><li>mining fossil fuels harms environment </li></ul>
  13. 13. impact of fossil fuels: <ul><li>oil spills cause pollution & kills marine life </li></ul>
  14. 16. impact of fossil fuels: <ul><li>burning fossil fuels releases harmful substances that causes air pollution, (incl. acid rain) & global warming </li></ul>
  15. 17. ACID RAIN FORMATION
  16. 19. conservation <ul><li>using only the resources you need </li></ul><ul><li>as efficiently as possible </li></ul>
  17. 20. recycling <ul><li>saving, collecting, or using materials again </li></ul><ul><li>instead of treating them as waste </li></ul>
