Sedimentary rocks

Further Explanation:

Sedimentary rocks are known to be the kind of rocks which are formed by the accumulation or disposition of the small particles which may be mineral or organic in nature and these particles are found on the floor of oceans or other water bodies at the surface of the earth. The study of these rocks is the main source for the understanding of the history of the earth which includes palaeo geography, pale climatology and the history of life.  

The study of the sedimentary rocks is known as sedimentology and it is known to be the part of both geology and physical geography and this study partly overlaps with the other disciplines of the Earth sciences. These rocks have also been found on Mars.
