Humidity and temperature are the keys to chemical weathering (and to answer a previous poster, chemical weathering is a natural process, though human activity can affect it.
Chemical weathering needs water, to act as a solvent and to transport corrosive ions so chemical weathering in arid climates, and in arctic climates (where water is frozen, and so not available) have little if any chemical weathering.
Chemical processes are also (mostly) accelerated by higher temperature so the high humidity and high temperature of the tropics is the place where chemical weathering predominates . Contribution of humic acids from soils is also important, and the high rate of growth of plants in tropical climates is also a factor.
While the solution of Limestones by acidified water is the most commonly quoted example, many minerals break down chemically, feldspar breaking down to clay minerals would be another important example.
Chemical weathering is generally more active in a temperate climate due to higher levels of moisture and precipitation, which can break down rocks through processes like hydration and oxidation. In contrast, desert climates often have lower precipitation levels, resulting in slower rates of chemical weathering on rocks.
In the Congolese rainforest, the rates of chemical weathering are likely higher due to the warm and wet climate, which accelerates chemical reactions that break down rocks. In contrast, in the Siberian steppes, mechanical weathering rates might be higher due to freezing and thawing cycles that physically break down rocks through processes like frost wedging.
A warmer climate would likely increase the rate of chemical weathering because higher temperatures can enhance the reaction rates of minerals with water and acids. This increased chemical weathering could result in faster breakdown of rocks and minerals into smaller particles and release of nutrients into the environment.
Cracks in rocks can accelerate weathering rates by providing more surface area for water and chemical agents to penetrate and break down the rock. Water can seep into cracks, freeze, expand, and further widen the cracks, leading to more rapid weathering. Additionally, cracks can provide pathways for plant roots and organisms to access the rock, enhancing weathering processes.

Two key factors affect the rates of weathering rock type and climate. Climate: is the single, most important factor that affects the rate of weathering. Chemical reactions occurs faster at higher temperatures, Warm climates favor chemical weathering, cold climates favor mechanical weathering(principally freezing and thawing), more moisture, or precipitation present, the more noticeable weathering.
Climate can affect rates of mechanical weathering by influencing the frequency of freeze-thaw cycles and differential heating of rocks, leading to physical breakdown. In contrast, climate can influence rates of chemical weathering by determining the availability of water and temperature for chemical reactions which can break down minerals. Both types of weathering are related as they work together to break down rocks - mechanical weathering initiates the process by breaking rocks into smaller pieces which exposes more surface area for chemical weathering to act upon.
The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.

Chemical weathering is most active in warm and humid climates. The combination of high temperatures and moisture speeds up chemical reactions that break down rocks and minerals. This type of climate provides the ideal conditions for chemical processes to occur, leading to increased rates of weathering.

Climate can affect rates of mechanical weathering by influencing temperature fluctuations, precipitation levels, and the frequency of freeze-thaw cycles. Chemical weathering, on the other hand, is influenced by factors such as the presence of water, oxygen, and acids in the environment. The two types of weathering are related in that they often work together to break down rocks: mechanical weathering weakens the rock's structure, making it more susceptible to chemical weathering, which further breaks down the rock's minerals.
Weathering speed depends on factors such as climate (temperature and precipitation), rock type and mineral composition, presence of vegetation, and human activities. These factors influence the rates of chemical, physical, and biological weathering processes.

There are not many factors which do not affect weathering in rocks.Two factors do not affect weathering are:Wind, sea and river erosion does not have any impact. No erosive processes cause weathering directly. Glaciers, however, may influence the climate of a region to the extent that more freeze-thaw weathering occursThe rock cycle does not affect weathering. This includes all actions and movements of rocks, though uplift and fault movement may cause more exposure to weathering, which may increase the rate of weathering
Two key factors affect the rates of weathering rock type and climate. Rock type: Minerals that dissolve easily weather faster, softer materials break apart more easily, porous minerals weather more easily.
