WATER CYCLE

WATER CYCLE

Water Cycleknown as thehydrological or H2O cycle.Continuous movement of water on Earths surface.Water moves from one reservoir to another.Waters natural cycle evaporation, condensation, and precipitation.Waters different phases-liquid, solid, and gas.Water cycle involves the exchange of energy

Water Cycle

Stages Of Water CycleEvaporation CondensationPrecipitation

Evaporationtransformation of water from liquid to gas.Energy source for evaporation issolar radiation.Total annual evapotranspiration 505,000km3(121,000cumi) of water

CondensationTransformation of water vapour to liquid water.Occurs in atmosphere when warm air rises.The Condensation rate is measure by Psychrometry.Responsible for the formation of the clouds.Condensation is a crucial component ofdistillation

PrecipitationWater vapour that falls on the ground.505,000km3(121,000cumi) of water falls as precipitation.107,000km3(26,000cumi) of water per year and snowing only.
