Detailed explanation-1: -Frost weathering occurs due to growth of ice within pores and cracks of rocks during repeated cycles of freezing and melting. This process is most effective at high elevations in mid-latitudes where freezing and melting is often repeated.

Detailed explanation-2: -Physical weathering process does not change the chemical and mineralogical composition from that of the parent rock, and it is more common near the ground surface.

Detailed explanation-3: -Ice wedging This refers to the repeated freezing and melting of water within small crevices in the rock surface. This expansion and contraction is also a major cause of potholes in streets. Water seeps into cracks in the rocks, and, as the temperature drops below freezing, the water expands as ice in the cracks.
