When temperatures drop, the … WebOct 4, 2010 · Frost wedging is a natural result of the fact that water expands when it freezes. If water gets into a fracture in a rock and freezes, it can expand and put pressure on the rock from within the fracture. Over time, successive cycles of freezing and thawing can cause this fracture to expand.
