When does frost wedging happen?

Answer 1

When Rain water enters into fractures and cracks in rocks

Due to the lower temperatures in the area, rainwater that seeps into cracks and fractures within the rock freezes, turning into ice that solidifies into a volume. This process of melting and freezing water expands the cracks and fractures within the rock and eventually causes rock breakage; this phenomenon is known as frost wedging.

Frost wedging occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart. This typically happens in cold climates during freeze-thaw cycles.
