Explanation:

This layering is an aftereffect of the procedure of transformative nature. Transformative nature is the changing of rocks by warmth and weight. During this procedure, rocks change either physically as well as artificially.

Changeable rocks structure from warmth and weight changing the first or parent shake into a totally new shake. The parent shake can be either sedimentary, molten, or significantly another changeable shake.
