Frost Wedging: Frost wedging occurs in places that have the right temperatures to freeze water and then melt water. This commonly happens in polar regions and mid latitude mountains where sunlight can melt water during the day and refreeze overnight when temperatures drop. Frost wedging is directly related to the fact that as water freezes its
Weathering – Physical, Chemical, Biological Weathering
Frost wedging. is the process by which water seeps into cracks in a rock, expands on freezing, and thus enlarges the cracks (Figure 5.1.1). 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.

Frost wedging is most effective in Canada’s climate, where for at least part of the year temperatures oscillate between warm and freezing. In many parts of Canada, the temperature swings between freezing at night and thawing in the day tens to hundreds of times a year.

Geography 12 Rocks: Frost Wedging
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. Erosion is a mechanical process, usually driven by water, wind GC43QP8 Felsenmeer (Earthcache) in New Hampshire, United States created by Nhtravelers5
