The weather conditions that least favor chemical weathering are cold and dry.
Climate plays an important role in the breakdown of rocks and soil into sediment and this process is called weathering. Rocks found in equatorial climates and exposed to lots of rain, humidity and heat weather faster than rocks in located in cold and dry areas. Chemical weathering typically happens when there is increase in the temperature and there is rainfall. Hence rocks in hot and wet climate experience faster rate of chemical weathering.
In a wet climate there is an acceleration of weathering due to mixture of dirt with Carbon dioxide and air and water causing weak acid which breaks down rapidly. Whereas, cold, dry climate accelerate physical weathering due to expansion and contraction of minerals within rock.
