There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Freeze thaw weathering occurs when water seeps into cracks in rocks or the pores between soil particles and freezes. The expansion of the water creates high pressures, which can widen the cracks or force apart the soil particles.

And are you satisfied with this answer?

Fancy that, RK Naresh asks a question, then answers it himself, again. Now we wait for the recommendations that he has lined up for himself.

No, it is physical weathering (mechanical). Freeze thaw weathering of rock is the disintegration of rock at cool temperature zone where ice formation is associated; the rock is broken into smaller particles opening pathway for erosion to act on outcrop.It become imperative since it can create a secondary fracture (fault or joint).
