How does freeze-thaw weathering occur?

Freeze-thaw weather occurs when water enters a small crack in a rock, which often happens during rainfall, then when temperatures fall to below 0 degrees celsius this water freezes and expands. This widens the crack in the rock and put pressure on it. The ice then melts, and when there is more rainfall this process repeats itself. When this happens over a prolonged period of time substantial weathering occurs and the rock is eroded.
