Temperature is one of the climatic factors which works by affecting the P/E ratio.   High temperature causes poor ratio and low temperature  causes good ratio. It works by affecting chemical reactions and influencing growth of various microorganism. Rainfall is another climatic factor which coupled with temperature, determines the process of soil development.
