Explanation

Layered or sedimentary rocks are formed when debris obtained from the breaking and weathering of rocks keeps getting deposited in water. Sedimentary rocks are formed not only in water but also by other agents of erosion such as wind, glaciers, etc. They contain adequate amounts of remains of organisms and plant fragments. Sedimentary rocks spread on the Earth’s surface are layered, i.e., they are deposited in strata.
