How are common sedimentary rocks formed
Sedimentary rocks can be subdivided into four groups based on the processes responsible for their formation: clastic sedimentary rocks, biochemical (biogenic) sedimentary rocks, chemical sedimentary rocks, and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes. Clastic sedimentary rocks are composed of rock fragments (clasts) that have been cemented to…
