What are Sedimentary Rocks

Filed under: Geography on 2021-10-09 06:32:51
Rocks of the earth’s surface area exposed to denudation agents and are broken up into various sizes of fragments.

These fragments are carried by various exogenous agencies and deposited.

These deposits through compaction turn into rocks. This process is called lithification.

In several sedimentary rocks, the layers of deposits maintain their characteristics even after lithification.

Sandstone, shale are some of the examples for Sedimentary Rocks.

Depending upon the mode of formation, sedimentary rocks are categorized into three groups:

Mechanically formed
Eg: Sandstone, conglomerate, limestone, shale, loess, etc.

Chemically formed
Eg: Chert, limestone, halite, potash, etc.

Organically formed
Eg: Geyserite, chalk, limestone, coal, etc.
