Geomorphology

Freezing water pries rock apart along cracks

In geomorphology, wedging refers to frost wedging (frost riving), a mechanical weathering process in which water in cracks and pores of rock freezes and the resulting ice growth and pressure prise the rock apart, progressively widening fractures and shattering it. The classic account attributes the force to the volume expansion of freezing water, while much modern work emphasises the growth of segregated ice that draws in unfrozen water. French's The periglacial environment reviews frost action and the debate over its mechanisms in cold-climate landscapes. The referent is a rock-breaking weathering process driven by ice, sharing only its name with the kneading of pottery clay.[1]
