Question

Difference between granular disintegration and exfloation

Answer 1

H!!!!.... FRIEND.........

.....HERE YOUR ANSWER.....

 Blook Disintiegration occurs in well-jointed rock just like granite........... In this rocks are split along the joints into larger rectangular shaped Blook......While Granular Disinitiegration process of physical or mechanical weathering due to repeated heat and cooling because of temperature change...........

.....HOPE ITS HELPFUL ANSWER FOR YOU.......

Answer 2

The mechanical weather involves breaking the pieces of rocks without changing its chemical composition. Some types of mechanical weather are:

a. Block disruption: When the difference between day and night temperature is greater, the rocks are expanded and contracted. They extend during the day, when the temperature is high and the contract occurs during the night when the temperature is very low. The result is in the division of rocks. This happens in areas where there is a lot of variation in day and night temperature. Examples in the desert

B. Granular dissolution: When weather agents reduce tiny minerals and fragments made of various minerals, it is called granular disintegration.

C. Removal: Changes in temperature can make fisher or rifts in rocks. Water then enters the outer layers of cracks and rocks. It is called exfoliation.

D. Frost Activity: In areas of great variation between day and night temperatures, rocks or fisher growing in rocks. Water enters these cracks. During the night, water accumulates in cracks due to the spread of rocks. During the day, the ice melts in the fishery of the rock. When this process is repeated several times, the rock breaks. This is called frost action.
