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.
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.
Atherosclerotic blockages most often occur in the coronary arteries that supply blood to the heart muscle, leading to conditions such as heart attacks. They can also occur in the carotid arteries supplying blood to the brain, causing strokes, and in the peripheral arteries of the legs, leading to peripheral artery disease.
Earthquakes infrequently occur away from plate boundaries. Most earthquakes occur at plate boundaries because of the stress caused by the interacting plates.
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.
