Sedimentary rocks

  1. 1. 1. Formation a. Weathering b. Erosion c. Deposition d. Compaction e. Cementation *LITHIFICATION=process to make sedimentary rocks*
  2. 2. a. Weathering – the breakdown of material at the Earth’s surface.g i. The weathered material is called SEDIMENT.
  3. 3. Did you Know? ¾ of rocks on the Earth’s surface are sedimentary?! ?!
  4. 4. ii. Sediment size varies – mud, sand, gravel
  5. 5. b. Erosion – movement of sediment from on place to another by WIND, WATER, or ICE.
  6. 6. c. Deposition – dropping off the sediment in a new location.
  7. 7. Now it’s time to put them together! d. Compaction (Squeezing) e. Cementation (Gluing)
  8. 8. A. Clastic Made from sediment such as clay, gravel, or sand
  9. 9. i. Sand becomes sandstone
  10. 10. Did you Know? The white house is built of sandston e!
  11. 11. ii. Clay and mud become shale
  12. 12. iii. Gravel becomes conglomerate.
  13. 13. B. Organic sedimentary rock is formed from previously living things. i. Limestone – ocean life ii. Coal – plant life on land
  14. 14. 4. Chemical sedimentary rock is formed from a chemical reaction such as water evaporating and leaving rocks behind.
  15. 15. i. Mineral crystals left behind in Death Valley after the water evaporates ii. Playa Lake in California – in the process of evaporating and leaving chemical rock behind
  16. 16. Mammoth Cave in Kentucky!!!!!
