8.1 Physical Weathering – Physical Geology – H5P Edition
Frost wedging (or ice wedging) happens when water seeps into cracks, then expands upon freezing. The expansion enlarges the cracks (Figure 8.4). The effectiveness of frost wedging depends on how often freezing and thawing occur.
Frost weathering - Wikipedia
Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes, such as frost shattering, frost wedging, and cryofracturing.

5.2: Weathering and Erosion - Geosciences LibreTexts
Weathering is a process that turns bedrock into smaller particles, called sediment or soil. Mechanical weathering includes pressure expansion, frost wedging, root wedging, and salt expansion. Chemical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation.
5.1 Mechanical Weathering – Physical Geology - Maricopa Open …
Frost 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.
5.1 Weathering – Physical Geography and Natural Disasters
Frost wedging is a type of mechanical weathering that occurs when water seeps into rock cracks, freezes, and pushes the cracks apart. Frost wedging is more effective in cold climates where freezing and thawing cycles are frequent.
A unified model for frost wedging in an open fissure under ...
2024年4月1日 · Long term observation of frost heave damage in fractured rock masses in the Alps revealed that the frost wedging in open fissures is more pronounced. 5 vol expansion due to the water-ice phase transition generates internal stress, potentially leading to crack propagation when the stress surpasses the geological body's strength.
Weathering: Definition, Types & Examples - Vaia
Frost weathering. Frost weathering, also known as ice wedging, is actually a collective term for the various processes involving ice, such as freeze-thaw, frost wedging and frost shattering. Freeze-thaw, also known as ice crystal growth, happens when water seeps into rock cracks, freezes, and thaws.
