What is meant by sedimentary rock? Describe the mode of formation of sedimentary rock.

Explanation

The word .sedimentary. is derived from the Latin word sedimentum, which means settling. All types of rocks of the earth.s surface are exposed to denudational agents, and are broken into various sizes of fragments. Such dn fragments are transported by different exogenous agencies and deposited.
These deposits through compaction turn into rocks. This process is called lithification. In many sedimentary rocks, the layers of deposits retain their characteristics even after lithification. Hence, we see a number of layers of varying thickness in sedimentary rocks like sandstone, shale etc.
