In temperate climates
Weathering by frost wedging is most effective in regions with freezing and thawing cycles, typically in colder climates. Regions with temperature fluctuations that allow water to seep into cracks in rocks, freeze, expand, and then thaw can cause significant mechanical weathering through frost wedging.
Any time water creeps into any object and freezes, it expands and causes damage. Water is everywhere. Cold weather is everywhere.
Frost wedging is most common in regions with fluctuating temperatures around the freezing point, particularly in areas where water can seep into cracks in rocks or pavement. This process occurs frequently in places with cold winters and warm summers, such as mountainous regions and northern latitudes. The repeated freeze-thaw cycles cause water to expand when it freezes, gradually widening cracks and breaking apart rocks.
The type of physical weathering that occurs when water enters cracks in rocks and freezes is known as frost wedging. When the water freezes, it expands, exerting pressure on the surrounding rock. This repeated freeze-thaw cycle can cause the rock to crack further and eventually break apart. Frost wedging is most common in climates where temperatures fluctuate around the freezing point.
Most pot chrysanthemums are not frost hardy and will need protection from freezing temperatures. If you want to overwinter them outdoors, you can provide insulation with mulch or bring them indoors in a protected area.
Frost wedging is one of the most important mechanical weathering processes. It occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Frost wedging is one of the most common forms of mechanical weathering. It occurs when water seeps into cracks in rock, freezes, expands, and ultimately breaks the rock into smaller pieces over time.
Frost wedging is the most common type of mechanical weathering in mountainous regions in middle latitudes. This process occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart. The combination of freezing and thawing cycles in these regions promotes rock breakdown through frost wedging.
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.

Mechanical weathering is most likely to occur in areas with frequent temperature changes, such as deserts or mountainous regions. The constant expansion and contraction of rock due to temperature fluctuations can lead to rocks breaking apart through processes like frost wedging and thermal stress.
The most common form of weathering is mechanical weathering, which breaks down rocks into smaller pieces without changing their chemical composition. This can happen through processes like frost wedging, root wedging, and abrasion from wind and water.
