its just water water cycle Flashcards
(4 cards)
water cycle 1
water in oceans,seas etc evaporate due to heat energy from the sun changing liquid water into water vapour
this vapour rises into the atmosphere
as it rises, it cools and condenses to form clouds- tiny droplets of liquid water
when these droplets become too large and heavy, they fall back to earth as precipitation, returning water to ground
some of the precipitation:
runs off surfaces and flows into rivers and seas (runoff)
infiltrates into the soil and rock to become groundwater (percolation)
water cycle 2
water in the soil is taken up by plants
it then leaves the plants through their leaves via transpiration which adds more water vapour to the air
WE (animals+humans) also return water to the cycle:
excrete water in urine and sweat
breath out water vapour in respiration
water cycle 3 death
dead plants and animals decompose and the organisms responsible (fungi and bacteria eg) may also respire, releasing water to environment
whole water cycle process is continous
