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