Water Cycle Explanation Class 9. Clouds are just masses of such water droplets. Biogeochemical cycle cbse class 9 biogeochemical reaction cbse class 9 water cycle evaporation condensation absorption percolation transpiration.
The sun which drives the water cycle heats water in oceans and seas. It is also known as the hydrological cycle or the hydrologic cycle. Thus the water present on earth has been in circulation since the evolution of the earth.
The sun which drives the water cycle heats water in oceans and seas.
It is a continuous process. The movement of water around our planet is vital to life as it supports plants and animals. The water vapour condenses causing the formation of droplets of water. Hence it does not have a starting or an ending point.
