water is the essential element for life. about 71% of the total Earth is covered by water, mostly in the form of rivers, sea, oceans and glaciers. similarly, the water cycle defines the processes through which the water on earth remains balanced for all living and non living things. there are various stages which occurs in equilibrium, such include;
1. Evaporation
2. Transpiration
3. condensation
4. precipitation
water evaporates, turns into clouds and condense to make rain and snow and came back to earth in the form of precipitation.
however there are times when the process of water cycle gets disrupt causing famine, drought, floods, tsunami etc, which is extremely dangerous for life on Earth.
