In temperate climates
Any time water creeps into any object and freezes, it expands and causes damage. Water is everywhere. Cold weather is everywhere.
in moist, mid-latitude climates
Physical (mechanical) weathering occurs when a rock is broken into smaller pieces without a change in chemical structure. Abrasion, fracture by freezing, plant root growth expansion of fractures, rock falls; these are forms of physical weathering.
A frost free refrigerator is not energy efficient. The most efficient refrigerators are the modern type but the ones that have a manual defrost. The mechanism that keeps the freezer free of frost uses a good deal of energy.

Frost wedging.
Any time water creeps into any object and freezes, it expands and causes damage. Water is everywhere. Cold weather is everywhere.
If it is cold, say, in Alaska, the most common effect on rocks is frost wedging. Frost wedging is when water gets in a crack in the rock, and the water freezes, making the rock crack a little more. When water keeps on going into the crack, and the ice gets bigger, it eventually will separate the rock into two or more parts, making the rock into many little rocks. I hope you find this useful! ^-^
in moist, mid-latitude climates
Frost wedging occurs in small cracks in the rock where water seeps in. The water then freezes and expands (fun fact: water is the only knowns natural substance that expands when freezing, and is also the only substance capable of existing in all three basic states of matter--liquid, solid, and gas--at naturally occurring temperatures), which then splits--or "wedges--the rock apart. I've attached an image for graphic demonstration.
