Water cycle:
 The water cycle is the process in which water moves from the land to the sky
and back again.
 The other name of water cycle is Hydrological cycle.
 It follows a cycle of evaporation, condensation and precipitation.
 Water evaporates from the surface of water bodies. The rising water vapour
cools down and condenses to form water droplets. These water droplets
collect together to form clouds.
 When the cloud become too heavy, water falls down the ground as rain.
Transpiration:
The process by which plants remove its excess water in the form of water vapor
through the spores present on leaves.
Precipitation:
The process by which water vapor present in the atmosphere condenses and falls
down as rain, snow or hail is known as precipitation.
Evaporation:
The process of conversion of water from its liquid state to Vapour state below its
boiling point is known as Evaporation.
Condensation:
The process of cooling down water vapour and converting to water droplets is known
as Condensation.
Percolation:
The process of collection of rain water by the earth surface is known as Percolation.
