Give a brief description of ‘Hydrological Cycle’.


  • Three-fourth of the earth’s surface is covered with water, but only a small proportion of it accounts for freshwater that can be put to use.
  • The process of hydrological cycle began with the evaporation process due to heat of Sun on all water bodies of the earth including seas and oceans.
  • These minute particles.of the water then get condensed. In this process of condensation, clouds are formed with dust particles and pollen grains present in the atmosphere.
  • When saturation takes place, then clouds precipitate in the form of rain or snow. This fresh water then becomes surface run-off water, in the form of rivers, ponds and lakes. This water again gets drained into sea or ocean and forms a hydrological process.
