Water seeps into cracks in the rock, and when freezing occurs, the water expands, thus making the crack slightly larger. This process is called mechanical weathering.
The weathering process caused by cycles of freezing and thawing of water in surface pores, cracks, and other openings

It is called frost heave, frost wedging, and freeze/thaw cycle, an example of mechanical weathering. Cracks formed in rocks by the pressure of freezing allow water to penetrate further, and enlarge the crack when that water freezes, gradually reducing the size of the rock body.

Freezing a rock would shrink it some (contract) while the thawing would expand it. This applies to most substances, water being the obvious exception.
If water is left in the pots they may crack from the freezing and thawing process.

Freezing or thawing are classified as mechanical weathering. Water dissolving and oxidation of chemicals in rock acid rain are classified as chemical weathering.
