The Water Cycle

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.

Water can be found in 3 states.

• Liquid- water, streams, lakes

• Gas- evaporation, clouds, fog

• Solid- ice, glaciers

{• Why do puddles

disappear on hot days?

• What is happening?

• Water is turning from a liquid to a gas!

EVAPORATION

{ {

Oceans account for 80% of water that is evaporated.

Precipitation• Process of when water in the

atmosphere falls to the earth’s surface.

Types of Precipitation?SNOW

RAIN

HAILSLEET

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 attatch 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

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
