describe water cycle thouroghly
first the water from oceans and lakes is heated by the sun and it turn into a gas that rises into the air(evaporation) then the coold air turns the gas drops back ino liquid becoming clouds(condensation)then the clouds get really heavy and rain snow hail or sleet falls down(precipitates) then the water is soked in soil(infiltration) and plants take the water(transpiration) the exces returns to oceans and lakes as runoff
