Sedimentary Rocks

Sediment are pieces of small material that come from the erosion of rocks or living things.


When sediment is deposited into layers by water or wind, sedimentary rock can be formed through erosion, deposition, compaction, and cementation.


Once sediment is deposited, it is compacted into layers from the weight of rock above.


The cementation of sedimentary rocks occurs when minerals fill the gaps between sediment creating a formation of solid rock.
