WebDefinition: Freeze-thaw weathering is a process of erosion that happens in cold areas where ice forms. A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making it larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the ... WebJul 5, 2024 · Freeze-thaw weathering occurs when rocks are porous (contain holes) or permeable (allow water to pass through). Water enters the rock and freezes. The ice expands by around 9%. This causes pressure on the rock until it cracks. Repeated freeze-thaw can cause the rock to break up. Find out more about weathering.

WebFrost 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. WebFreeze-thaw weathering (also called frost shattering) is an erosion process that results when groundwater, rainwater or melted snow enters pores or joints in rock and then breaks the rock through frost wedging. Freeze-thaw weathering is a common occurrence in all parts of the world where the temperature sometimes goes below freezing. WebOr, changes in temperature cause water to freeze and expand, melt and contract leading to freeze-thaw weathering.
