Definition of block disintegration within 250 words

Answer 1

Answer:

Explanation:

Block disintegration occurs in well-jointed rock just like granite. And, it is particular effective in areas with great diurnal range of temperature somewhere between 10-15 degree celsius and areas with barrel rocks without  a protective vegetative cover. In this rocks are split along the joints into larger rectangular shaped block.

While Granular disintegration process of physical or   mechanical weathering due to repeated heat  and cooling because of temperature change. As a result of alternative expansion and contraction of minerals in rocks causes the rock to break down into small pieces.
