EFFECTS OF WATER CYCLE

regulates the temperature of the surroundingschanges weather and creates rainhelps in conversion from rock to soilcirculate important minerals through the

spherescreates the many geographical features on

earth like the ice caps of mountains, icebergs, the rivers and the valleys, lakes and more.

EVAPORATION A process where water at the surface turns into water vapors. Through evaporation water moves from hydrosphere to atmosphere.

sublimationA process where ice directly converts into water vapors without converting into a liquid water.

CONDENSATIONThe process by which water vapor in the air is changed into liquid water.

PRECIPITATION The fall of water, ice, or snow deposited on the surface of the Earth from the atmosphere.

TRANSPIRATIONA process similar to evaporation where liquid water is turned into water vapor by the plants.

RunoffThe process where water runs over the surface of earth

InfiltrationThe process where water moves deep into the soil.
