The freeze-thaw weathering process can be driven by ice segregation or, theoretically, by the 9% volume expansion of water upon freezing. As a joint widens under …
WebFrost wedging is the process by which water seeps into cracks in a rock, expands on freezing, and thus enlarges the cracks (Figure 5.5). The effectiveness of frost wedging is related to the frequency of freezing and thawing. Frost wedging is most effective in a climate like Canada’s. In warm areas where freezing is infrequent, in very cold ... WebA large crevasse formed at the back of a corrie glacier between the ice attached to the headwall and the moving glacial ice. Less powerful erosion, as a result of rotational movement. This may have moraine deposits. Occurs at the base of the hollow, deepening it.
WebJan 5, 2024 · Frost weathering is the process by which water freezing in ice causes mechanical weathering, which can take various forms, such as frost shattering, frost wedging, and cryofracturing. It can occur over short or long periods and at different scales, from breaking apart individual mineral grains to shattering large boulders.
