notes with tooltips [water cycle]
1
These notes are about the Water Cycle. Explaining how seawater becomes rain and runs back into the sea as freshwater.
2
The first stage is called EVAPORATION. This is where the Sun heats up the surface of the sea. Changing the liquid into a gas.
3
CONVECTION occurs when this gas is warmed and rises above colder water below.
4
However, as the gases rise they get cooler and turn into WATER VAPOUR. This is half way between gas and liquid.
5
The second stage is called CONDENSATION. This is when the water vapour cools to form clouds.
6
As the clouds are blown on-shore they rise. They cool and the water vapour begins to change back into a liquid.
7
The third stage is PRECIPITATION. This is when the water vapour cools and changes back into a liquid.
8
This falls as rain, sleet or snow depending on the temperature. As you know water flows downhill creating the final stage RUN-OFF.
9
To recap :
there are 4 stages. 1.EVAPORATION 2.CONDENSATION 3.PRECIPITATION 4.RUN-OFF

Here is an animation showing the whole water cycle in action.
