The contribution of temperature in controlling the rate of reaction of weathering is identified by difference in the rate of reaction in the temperate and tropical regions. Other factors of intensity like accumulation of organic matter, hydrolysis, and leaching operation are also affected by the temperature. Stephens et al., in the year 1949 [54–56], reported that the air temperature index given by Szymkiewicz et al. in the year 1947 [57–59], T = 2.5t/10, where t represents the temperature of air in degree centigrade that is related to the chemical weathering rate. The significance of temperature on the rate of reaction involved in chemical weathering is shown by accomplishment of latosolization even on rocks which are acidic in nature, subject to condition intensity factor are sufficiently large. According to Williams et al., in the year 1949. [60–62], it was reported that minerals chemical weathering is highly comprehensive in cool temperature regions, also in presence of snow cover. Retzer et al., in the year 1949 [63–65], reported mineral colloids formation in the Rocky Mountains old soils, where cold temperature condition exists.
