3. WATER CYCLE
PROCESS
The liquid water
evaporates and
change into a gas.
The gaseous vapour
cools and become
again into a liquid.
This process is
condensation.

4. WHAT AFFECTS
EVAPORATION?
The velocity of evaporation
depends on water body size, heat
energy, atmospheric pressure and
air movement:
● Water body size is about the
surface it has. It the surface
is bigger it is going to
evaporate more quantity.
● Heat energy causes water
molecules to vibrate. As they
vibrate molecules can scape
easily.

5. how does
precipitation
occurs?
Condensation is
when water
vapour returns to
liquid. Rising
vapour cools and
condenses into

6. What is the difference
between weather and
climate?
Condensation is
when water
vapour returns to
liquid. Rising
vapour cools and
condenses into

7. What other
processes affect
the weather?
These processes are also
important:
● Astronomical parameters –
Earth’s rotation, which
affects circulation in oceans
and atmosphere.
● Earth’s eccentricity – the
Earth’s axis, which
determines the intensity
of the incoming solar
