What kind of energy conversions sustain the water cycle in nature?

1.	What kind of energy conversions sustain the water cycle in nature?
Answer» Water cycle and conversation of energies : 1) The Sun heats water in oceans and seas. Then water evaporates as water vapour into the air. Here potential energy converts into kinetic energy. 2) Rising air currents take the vapour up into the atmosphere. There cooler temperatures cause it to condense into clouds. Here kinetic energy converts into potential energy. 3) Air currents move water vapour around the globe, cloud particles collide, grow and fall out as rain. Here potential energy converts into kinetic energy. 4) Run off and ground water are stored as fresh water in lakes. Some precipitation falls as snow or hail. Here kinetic energy converts into potential energy.

Water cycle and conversation of energies :

1) The Sun heats water in oceans and seas. Then water evaporates as water vapour into the air.

Here potential energy converts into kinetic energy.

2) Rising air currents take the vapour up into the atmosphere. There cooler temperatures cause it to condense into clouds. Here kinetic energy converts into potential energy.

3) Air currents move water vapour around the globe, cloud particles collide, grow and fall out as rain. Here potential energy converts into kinetic energy.

4) Run off and ground water are stored as fresh water in lakes. Some precipitation falls as snow or hail.

Here kinetic energy converts into potential energy.
