प्रश्न
Describe the process of evaporation together with factors that favour it.
उत्तर
For evaporation excessive heat and the presence of water, bodies are essential. Nearly 600 calories of heat is required to change water into water vapour. Evaporation is maximum in tropical belt and mainly in a hot desert region surrounded by water bodies. In the equatorial belt, due to overcast with clouds, evaporation is comparatively less due to obstacles of cloud in the heating process.
