by the coldness of freezing and the warmness of thawing
Frost wedging
water; wind
very slow downhill movement of rock and soil
A cycle of freezing and thawing can break down any rock, no matter how big or heavy it is. If water gets into small cracks, then freezes, it will expand and push the rock crystals apart.
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.
If water is left in the pots they may crack from the freezing and thawing process.

blonde people are not as smart
For example,when ice thaws, it becomes water, which can go into holes of a rock. When the water freezes, it expands & puts pressure on the rock which causes it to break apart/weather
Freezing or thawing are classified as mechanical weathering. Water dissolving and oxidation of chemicals in rock acid rain are classified as chemical weathering.
