clastic sedimentary by the processes of compaction and cementation
1. Chemical sedimentary rocks 2. Chemical sedimentary rocks are formed from sediments created by rocks being broken down into small particles (clasts). 3. Chemical sedimentary rocks are formed from sediments created by dissolved chemicals being precipitated out of the water they're dissolved in.
Sedimentary rocks form from broken-down pieces of existing rocks through weathering, erosion, and lithification processes. These rocks are created when sediments are compressed and cemented together over time. Examples include sandstone and limestone, which illustrate how sedimentary rocks can originate from different types of sediments.
