    Chemical weathering reactions (especially the formation of clay minerals) and biochemical reactions proceed fastest under warm conditions, and plant growth is enhanced in warm climates. Too much water (e.g., in rainforests) can lead to the leaching of important chemical nutrients and hence to acidic soils.

    Physical weathering happens because of multiple processes like volume changes of minerals, frost wedging and in the end, results in mechanical disruption of rocks. Chemical weathering, on the other hand, is the result of the decay of rock forming minerals caused by temperature, water, hydrogen, oxygen and mild acids.
