GEOLOGY

Detailed explanation-1: -1) Clastic (detrital) sedimentary rocks are composed of the solid products of weathering (gravel, sand, silt, and clay) cemented together by the dissolved weathering products.

Detailed explanation-2: -Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

Detailed explanation-3: -This process is called cementation. After compaction and cementation the sedimentary sequence has changed into a sedimentary rock.

Detailed explanation-4: -Sedimentary rocks that form from sediments are called “clastic rocks. “ Clastic rocks are rock fragments that are compacted and cemented together (Figure below).
