1. Sedimentary Rocks

2. Made from sediments or rock material that has been broken down in some way. Sedimentary rocks are usually formed in a watery environment. Often layered Are the only rocks that contain fossils

3. Clastic (fragmental) –made by compaction and cementation of sediments. Clastic rocks are identified by the size of the fragments. Types of Sedimentary Rocks

4. Mixed

5. Conglomerate has rounded fragments

6. Breccia has angular fragments

7. Chemically formed rocks: evaporites Formed when water carrying minerals evaporates and leaves the minerals behind. Are identified by the minerals present (ie halite hardness of 2.5)

9. Bioclastic- bio= life clastic= fragments Made from accumulated shells (limestone) or plants (coal)
