Sedimentary rock

  1. 1. Friday, January 30, 2015 The Earth’s Crust Sedimentary Rock
  2. 2. Activity: Shake your bottle and observe. Draw a picture showing the layers of sediment that formed. Which sediments ended up on the bottom? Why? Which sediments ended up on the top? Why? What might happen to the sediments if the water in the jar completely evaporated?
  3. 3. 2. Sedimentary Rock – (“Layer’s of rock”) – “Nature’s Cement” sedimentary rock – rock that is made from sediments that usually form in layers
  4. 4. sediments – loose materials such as sand, mud, and gravel (and plant and animal remains – fossils)
  5. 5. These sediments are moved by water, wind, and gravity and settle on top of each other in layers (called beds).
  6. 6. As these layers of sediment slowly pile on top of each other, they become tightly packed or cemented together to form rock
  7. 7. Mississippi Delta
  8. 8. These beds push on the layers below and create enough pressure to form sedimentary rock – compaction
  9. 9. Or, as dripping water coats the sediment with dissolved minerals and cements the pieces together – cementation.
  10. 10. E.g. mudstone (shale), sandstone, limestone, and conglomerate Vide o
