Mechanical Weathering is the mechanical breakup or disintegration of rock
into smaller fragments. Its a surface or near surface process. A rock
falling from a cliff eventually impacting with the earth's surface, sand
grains carried by wind or water, and glacial ice scours. There are different types of
mechanical weathering which are given below.
