Explain the hydrological cycle

The cyclic movement of water from the atmosphere to the Earth and back to the atmosphere through various processes is called as water cycle.
Different steps of water cycle include evaporation, transpiration, condensation, precipitation and surface run-off.
Evaporation - The water present on the surface of oceans evaporates by the sun’s heat. This process of conversion of water from liquid state to vapour state is called evaporation. Evaporation also takes place from wet clothes, fields, ponds, lakes and rivers.
Transpiration - Plants take in water from the soil to prepare their own food and also for other life processes. They release excess water into air in the form of water vapour by the process of transpiration.
Condensation - The evaporated water is carried away by warm air. As the warm air moves higher from the surface of the Earth, it starts to cool down. This water vapour condenses to form tiny water droplets which float in air to form clouds or fog.
