What is a hydro logical cycle?

उत्तर
The water of the ocean is evaporated in large amounts into the atmosphere and then condensed into clouds, fog, mist, etc. After the dew point arises, precipitation takes place and fill up the fresh water bodies of the land surface. Again the water flow goes into the ocean and in this way a complete hydrological cycle works on the earth. This is beneficial for life on the earth, as fresh water is provided for agriculture and other occupations.
