Sedimentary rocks amber felipe

  1. 1. Sedimentary rocks By: Felipe Amber
  2. 2. Here are some examplesof a sedimentary rock 
  3. 3. The first example is the sandstone -sandstone is sand grains cemented togetherinto a solid stone
  4. 4. The second example is siltstone : siltstone ismade from silt partials cemented together
  5. 5. The last sedimentary rock is breccia : Breccia is madeup of angular pebbles cemented together.
  6. 6. Sedimentary rocks are made from: Weathering: weathering is the breaking down of a rock Erosion : the movement of sediments Deposition : where eroded sediments end up Sediments : pieces of weathered rock Compacted : one sediment are squished together to form sedimentary rock Cemented : when sediments are glued together crystallization to form sedimentary rock Fossils : fossils are the preserved remains
  7. 7. Fun Facts About SedimentaryRocks Sediments can harden into sedimentary rock in lots of ways. pressure-As layer after layer of sediments are deposited, the lower layers are pressed together under the weight of the layers. Earths surface is constantly being eroded. It means that rocks are broken up into very small pieces by weathering agents such as wind, water, and ice.
