The Water

Cycle

The Water Cycle

consists of….

•Evaporation/transpiration•Condensation•Precipitation•Run-off

We reuse water

everyday. It works as an

endless cycle.

The Earth is very limited in

Fresh Water. We have to

use and reuse what we

have.

TranspirationSimilar to evaporation, only water is evaporated off of the leaves of plants after it is absorbed through the roots

{ {

Oceans

account for

80% of water

that is

evaporated.

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

This process forms clouds!

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

Precipitation• Process of when water in the

atmosphere falls to the earth’s surface.

SNOW

RAIN

HAILSLEET

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.

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

Majority of water movement is

contributed by the melting of

snow caps

- Snow caps act as a natural reservoirs

We need fresh water to

survive, so use it

efficiently!
