Sedimentry Rocks
Sedimentary rocks are made from chemical reactions and/or from sediment. Water, wind and ice can move sediment to a place where it settles. There are 3 types of sedimentry rock, fossils, cementation and compaction. Fossils are either traces or remains of a plant animal or any other organism(living thing). Cementation is the process of pieces of sediment being held together by a material. Lastly, compaction is when each layer of sediment is getting squished together by a material.
