The agriculture activities on the terrain are the only real and lasting source of wealth, and it is in a large measure dependent on rainfall. The crop production fluctuates with the rainfall in such a way as to leave no doubt that the rainfall has been the real component, and the carrying capacity of grazing land in head of stock per square kilometer emphasis the same truth. It also influences the rate of evapotranspiration from vegetation and soil, which not only, affects the production of crops but also increases the ratio of moisture in atmosphere. The size and growth of vegetation is also closely related to the amount of rainfall. Sometimes, it also plays vital role in the industrial location and diseases controlling of an …show more content…
An air should be called saturated, when its relative humidity reaches to 100 percent. It is also specific determinant of the amount and rate of evapotranspiration and critical climate factor in the rate of moisture loss by plants and animals, including human beings. It also expresses the average condition of water vapors in atmosphere. Relative humidity has also a physiological significance, as it determines the efficiency of the water-evaporating phase of our body cooling mechanism. It is also an important source of all forms of condensation and precipitation, where there is little moisture in the air; the precipitation will be low as compared to high atmospheric moisture. As the air is a principal absorber of solar energy and earth radiant energy as well, water vapor operates as a heat regulator and so have great effects on air
