Question

distinguish between granular disintegration and block disintegration in points

Answer 1

GOOD MORNING ☺️

Block disintegration is when the rocks split along joints forming large rectangular shaped blocks. ... Granular disintegration is when grains of a rock become loosened and fall out, to leave a pitted, uneven surface because of changing temperature. Rocks are made up of different types of minerals.

$\huge \purple {ANSWER}$

Block Disintegration

★Block disintegration is when the rocks split along joints forming large rectangular shaped blocks.

★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.

★In block disintegration, a rock disintegrates due to the change in temperature. This change causes the outer layers of the rock to expand and contract continually. This eventually disintegrates the rock.

Granular Disintegration

★Granular disintegration is when grains of a rock become loosened and fall out, to leave a pitted, uneven surface because of changing temperature. Rocks are made up of different types of minerals.

★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.

★In granular disintegration, a rock disintegrates due to frost action. The water in between the rock particles undergo freezing and thawing alternatively. The same process happens to the water in crevices or gaps between the rock particle.
