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

Frost Wedging.
Freezing a rock would shrink it some (contract) while the thawing would expand it. This applies to most substances, water being the obvious exception.
creep mass movement occurs where ice wedging takes place.(ice wedging means the ground is freezing and thawing over and over again) As the ground freezes, it expands the water in the soil to push up the sediments. when the ground thaws out all the sediments will fall downslope. Creep is a slow process.
If water is left in the pots they may crack from the freezing and thawing process.
