Water is extremely important, even for physical weathering. The more water present, the faster weathering occurs. Temperature is also important. Warmer temperatures promote faster reactions, so chemical weathering is more effective in warm climates. Climate plays a major role in chemical weathering, warmer temperatures makes chemical reactions happen faster and as a result minerals weather faster in warmer more humid climates. Water is a huge part of chemical weathering as well because the water causes the dissolution of minerals in the rocks. Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering and rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

The chemical weathering or the material deterioration due to the presence of air pollutants is, in general (alongside the concentration of the main pollutant like sulphur dioxide, ozone, PM, etc.), proportional to the air temperature and the humidity, hence both factors accelerates the chemical processes. Thus, the weathering is stronger in warm and humid climate compared with dry and cold. The rate of weathering is quantified by the so called dose-response functions which are empirically derived after year-long field experiments. See the (already old) publications in the attached files as well as the citations therein.

Dear Hristo Chervenkov thank you for your contribution to the discussion

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering and rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering. This happens because plants and bacteria grow and multiply faster in warmer temperatures. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates. Water is the main agent of weathering, and lack of water slows weathering. Precipitation occurs in deserts, only less than in other climatic regions. Chemical weathering proceeds more slowly in deserts compared to more humid climates because of the lack of water. A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering. A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering. Chemical weathering is most intense in areas that have abundant water. Different minerals weather at different rates that are climate dependent. Ferromagnesian minerals break down quickly, whereas quartz is very resistant to weathering. Climate plays a major role in chemical weathering, warmer temperatures makes chemical reactions happen faster and as a result minerals weather faster in warmer more humid climates. Water is a huge part of chemical weathering as well because the water causes the dissolution of minerals in the rocks.
