Freeze-Thaw Weathering: How it Affects Subgrade Soils
Web11 de mai. de 2014 · Freeze thaw weathering on a cliff breaks the rocks up into smaller pieces which can then free fall. This occurs commonly on cliffs with lots of joints as the joints make it easier to break up the rock. If the cliff is undercut by the sea, it can loose some of its stability, increasing the likelihood that a rockfall will occur. Soil Creep WebProcesses of glacial erosion.
