Q

water cycle 1

A

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

Q

water cycle 2

A

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
