WebFreeze-thaw weathering is common in mountainous areas where the temperature is around freezing point. This type of weathering is caused by the expansion and contraction of water within porous rocks. As ice crystals form, they grow larger, attracting liquid water from the surrounding pores. 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.
