The sun heats the water in oceans, rivers, puddles and even laundry hanging on clotheslines. The droplets evaporate and heat up into the air as water vapour.
When the water vapour rises into the cooler air above the earth, it condenses or turns back into liquid water droplets. The droplets then collect and form clouds.
As the clouds cool and become saturated, they release the water back to the earth as rain, hail or snow.
Some of the precipitation moves downwards, percolating through pores and cracks in soil and rock. the excess becomes overland runoff into creeks, rivers and lakes.
Some precipitation falls into lakes and streams, or is fed directly to these water bodies and water courses over land or via the water table.
Some of the water returned to the earth soaks into the ground and replenishes underground reserves.
Water vapour absorbs into the air from leaves of trees and other plants.
