How can you distinguish a clastic sedimentary rock from a chemically formed sedimentary rock?


Chemically formed sedimentary rocks are formed from fossils that are from an organic sediment. Clastic sedimentary rock forms when we get sediment from a process called weathering a process that crushes outsized rocks into bits, so the answer of how we get clastic sedimentary rock is the sediment comes together and hardens together to make one piece. The sediments could be particles of rock, sand, minerals, or organic material.
