In locations with an average yearly temperature of 5 degrees and average yearly precipitation of 45 cm, mechanical weathering processes such as frost action and freeze-thaw cycles are most common. The repeated freezing and thawing of water in rocks can lead to the breakdown of rocks into smaller pieces due to the expansion and contraction of water.
In areas with an average yearly temperature of 5°C and average yearly precipitation of 45 cm, physical weathering processes such as freeze-thaw weathering are more common. The repeated freezing and thawing of water in cracks and crevices can break down rocks into smaller pieces due to the expansion and contraction of water as it freezes and thaws, eventually leading to rock breakdown.
Signs of weathering include the gradual disintegration or wearing away of rocks and other materials on the Earth's surface due to exposure to environmental factors such as water, wind, and temperature changes. Common signs of weathering include cracks, fractures, flaking, and the rounding of sharp edges or corners on rocks and other structures. Weathering can also lead to the formation of soil and sediment.
The factors that determine the rate of weathering include the type of rock or material being weathered, the climate of the region (temperature and precipitation), the presence of vegetation and soil cover, as well as human activities such as mining and construction. Chemical weathering is more prominent in warm and humid climates, while physical weathering is more common in cold and dry climates.
Physical weathering from temperature changes would likely be least common in regions with stable and moderate climates, such as tropical rainforests or areas along the equator where there are minimal temperature fluctuations throughout the year.
Physical weathering from temperature changes would be least common in polar regions where temperatures remain consistently low, as there is little variation in temperature to cause the expansion and contraction of rocks.

Physical weathering is any process that causes erosion. Volcanic eruptions, wind, precipitation and earthquakes are the most common forms.

Physical weathering from temperature changes would likely be least common in regions with stable and moderate climates, such as tropical rainforests or areas along the equator where there are minimal temperature fluctuations throughout the year.
Physical weathering from temperature changes would be least common in polar regions where temperatures remain consistently low, as there is little variation in temperature to cause the expansion and contraction of rocks.
Physical weathering from temperature changes is most common in regions with extreme temperature fluctuations, such as deserts or high mountain areas. These areas experience large temperature variations between day and night, causing rocks to expand and contract, leading to weathering. Additionally, regions with frequent freeze-thaw cycles, like in polar regions or high altitudes, are also prone to temperature-induced weathering.
Chemical weathering occurs when rock is broken down and dissolved through chemical reactions. It can happen anywhere, but is more common in areas with high moisture and temperature fluctuations, such as tropical regions and near coastlines.
Climates are classified based on temperature and precipitation patterns. The most commonly used classification system is the Koppen Climate Classification which divides climates into categories based on average monthly temperature and precipitation. This system helps identify and map different climate types around the world.
In Mica, exfoliation is a common form of physical weathering where thin sheets of mica peel off due to changes in pressure and temperature. In Shale, frost wedging is a common type of physical weathering where ice expands in cracks, causing the rock to break apart.
In cold regions because ice wedging also known as frost wedging physically breaks apart rocks.Ice wedging causes cracks in rock to expand as water seeps in and freezes. So colder regions is where it is least common for physical weathering to occur from temperature changes.
