Frost Wedging (Geography)

Caused by the repeated freeze-thaw cycle of water in extreme climates. Water seeps into the joint or cracks in rocks. When it then freezes, the expanding ice places pressure on the joints in the rock. Finally, when the pressure is too much, the joint expands. In some cases, the rock will split, though this usually happens after repeated freeze and thaws. As new water is added during the warmer days, more ice is created at night, wedging the joints apart further

Frost Wedging (Geologic)

A process that mechanically breaks apart rock caused by expansion of water as it freezes in cracks and crevices.

Frost Wedging (Physical Geography)

A process of physical weathering in which water freezes in a crack and exerts force on the rock causing further rupture.
