If the tempyure goes below freezing at night how does ot affect a rock?

When temperatures drop below freezing at night, water that has seeped into cracks in the rock can freeze and expand. This expansion can exert pressure on the rock, leading to the phenomenon known as freeze-thaw weathering, which can cause the rock to crack and break apart over time. Repeated cycles of freezing and thawing can significantly weaken and fragment the rock, contributing to erosion and landscape changes.
