WebFreeze-thaw weathering (also called frost shattering) is an erosion process that results when groundwater, rainwater or melted snow enters pores or joints in rock and then breaks the rock through frost wedging. Freeze-thaw weathering is a common occurrence in all parts of the world where the temperature sometimes goes below freezing. WebPhysical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart.
