Solution
The correct option is C granular weathering Weathering is a process used to explain the breakdown of the rocks due to exposure to the atmosphere. Weathering down of the rock into small pieces is called disintegration. It is in granular weathering, when water penetrates through the rocks, the particles get loose and separate from the main rock. It is a process where a rock disintegrates due to frost action. The water in the rocks freezes as well as liquify at the same time. The rock disintegrates because of heating and cooling at the same time, which result in the expansion and contraction of minerals in the rock breaking it into small pieces.
