How Can Freezing And Thawing Cause Weathering. One common type of physical weathering is ice or frost wedging. Typically, ftcs are defined as the total number of times.
This repeated freezing and thawing creates ice wedges, which can cause rocks to break. As ice forms in the cracks of a street, the water expands and pushes against the surrounding rock, making the cracks wider, eventually breaking apart the rock. Water underneath the pavement is meant to drain away, but during winter it freezes in the base and subgrade materials.
