When the temp of the air is cold enough to change the water molecules from gas to a liquid.

1. The Water
Cycle

2. The Water Cycle
consists of….
•Evaporation/transpiration
•Condensation
•Precipitation
•Run-off

3. We reuse water
everyday. It works as
an endless cycle.

4. The Earth is very limited
in Fresh Water. We have
to use and reuse what
we have.

5. Transpiration
Similar to evaporation, only water is
evaporated off of the leaves of plants
after it is absorbed through the roots

6. { {
Oceans
account for
80% of
water that is
evaporated.

7. What Happens Next?
The process of condensation
occurs•When the temp of the air is cold
enough to change the water
molecules from gas to a liquid
•Water droplets form when small
dust particles are present for the
water to attach to

8. This process forms
clouds!

9. The water eventually has to come
down…
1)Water condenses onto tiny
particles
2)Droplets collide and grow in
size and weight
3)Enough collision occur to
override the updraft speed
4)Droplets fall

10. Precipitation
• Process of when water in the
atmosphere falls to the earth’s surface.
SNOW
RAIN
HAIL
SLEET

12. Water that falls as rain and snow infiltrates
into the subsurface of soil and rock. Some
stays in the the soil, some may enter a
stream, and some may infiltrate deeper
and recharge ground aquifers.

13. How do we use
ground water?
•Pump water out of wells
•Create dams to channel water into
aquifers
•We depend on stored water for
daily use

14. Majority of water movement
is contributed by the
melting of snow caps
- Snow caps act as
a natural
reservoirs

15. We need fresh water
to survive, so use it
efficiently!
