Physical weathering is most likely to occur in climates with frequent temperature changes, such as in deserts and mountainous regions. These areas experience daily temperature fluctuations that contribute to the expansion and contraction of rocks, leading to physical weathering processes like freeze-thaw cycles and exfoliation.
Physical weathering is a dominant process because it occurs continually through various forces such as temperature changes, frost action, and abrasion from wind and water. These factors break down rocks into smaller pieces, increasing the surface area for further weathering processes to occur. Additionally, physical weathering is not limited by environmental conditions and can take place in various climates and geologic settings.
Lots of rain, wind, freeze/thaw cycles. Hot, humid climates with high rainfall promote chemical weathering.
In hot and dry climates, there is less moisture available for chemical reactions to occur, which slows down the weathering process. Additionally, the lack of water reduces the formation of frost wedging and other physical weathering processes that rely on water freezing and expanding. The high temperatures can also increase evaporation rates, further limiting water's role in breaking down rocks.
Mechanical weathering can occur in any type of climate, but it is more prominent in cold and dry climates where freeze-thaw cycles and temperature changes can break down rocks.
Chemical weathering is accelerated in hot wet climates because higher temperatures and moisture levels increase the rate of chemical reactions that break down rocks. In cool dry places, chemical reactions occur more slowly due to lower temperatures and limited water availability, which hinders the process of chemical weathering.
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
Wet. Hot and wet climates allow for the fastest weathering.

There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
Climate does play a role in the rate of weathering. In areas with higher temperatures and more precipitation, chemical weathering processes like dissolution and oxidation tend to occur more rapidly. In colder or drier climates, mechanical weathering processes such as frost wedging may be more prevalent.
Physical weathering can enhance chemical weathering by increasing the surface area available for chemical reactions to occur. This is because physical weathering breaks down rocks into smaller pieces, exposing more surface area to chemical processes like oxidation and hydrolysis. So, physical weathering does not inhibit chemical weathering; instead, it can actually facilitate it.
Chemical weathering is accelerated in hot wet climates because higher temperatures and moisture levels increase the rate of chemical reactions that break down rocks. In cool dry places, chemical reactions occur more slowly due to lower temperatures and limited water availability, which hinders the process of chemical weathering.
Physical weathering can occur at varying speeds depending on factors such as the type of rock, climate, and environmental conditions. In general, physical weathering tends to be a slow process compared to chemical weathering, as it involves physical forces like wind, water, and temperature changes breaking down rocks over time.
Chemical weathering occurs faster in hot climates because high temperatures accelerate chemical reactions, increasing the rate of breakdown of minerals. In hot climates, there is also typically more moisture which can further speed up the chemical weathering process. Additionally, biological activity is often more prevalent in hot climates, which can also contribute to chemical weathering.
