Transcript

  • 1. L.O:weathering, erosion, deposition
  • 2. When rocks are exposed to theenvironment, they can weather (breakdown).
  • 3. Weathering when rocks breakdown intosediment (rock particles)because they are exposed to theenvironment
  • 4. Two kinds: physical and chemicalweathering
  • 5. Physical weathering rocks breakdowninto sediment (small rock particles)caused by ice or biological activity
  • 6. Chemical weathering: when theminerals in rocks dissolve or rustfrom oxygen or acid rainChemical weathering happens in warm (hot) andhumid (wet) environments.
  • 7. Water is the greatest cause ofweathering.
  • 8. Small rocks weather faster than bigrocks
  • 9. Small rocks weather faster than bigrocks
  • 10. Rocks with soft minerals are lessresistant to weathering
  • 11. Rocks with harder minerals are moreresistant to weathering
  • 12. Soil is the result of the weathering ofrocks and biological activity.
  • 13. Erosion: when sediment (rockparticles) are transported away.Wind, gravity, ice (glaciers) andespecially running water are agentsof erosion
  • 14. Streams:Streams (rivers) are moving water.
  • 15. A stream’s velocity depends on its• Gradient (slope)• Discharge (volume of water it carries)
  • 16. The meander (outside of the bend) ofa stream has the MOST erosion.
  • 17. “C” has most erosion
  • 18. Inside the bend (meander) has mostdeposition (“A”).
  • 19. Which has more erosion? Which hasmore deposit?
  • 20. Streams create V-shaped valleys
  • 21. Streams create V-shaped valleys
  • 22. Complete page 74.
  • 23. Glaciers are huge slow-moving“rivers of ice”.Glaciers transport all sizes of rocks asthey move.
  • 24. Glaciers create U-shaped valleys.
  • 25. Deposition:When agents of erosion deposit thesediments they carry.
  • 26. Deposition: When agents of erosiondeposit the sediments they carry.
  • 27. Streams deposit sediment withhorizontal sorting.• As a stream slows down: theLargest, heaviest, Roundest and densestparticles are deposited first.
  • 28. Glaciers deposit unsorted (mixed-uprocks) piles .
