Water Cycle

By: Mr. Danny

The Driving force of the Water Cycle

Lake Erie has a huge role on the Water Cycle

4. Rain water falls to form rivers.

THE WATER CYCLE 4 3 3. Water vapour condenses to form clouds 2 2. Water vapour is carried up into the air.

5 5. Rivers flow into the sea 1. Water evaporates 1

Accumulation 97% of water is ocean Salt Water 3% Fresh water Glaciers, Ground water, Lakes, Swamps Rivers

Evaporation

• Heat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor. • This is called

evaporation

. • The vapor rises into the air and collects in clouds.

Condensation

• Water vapor collects in clouds. As the clouds cool the water vapor condenses into water drops. • This is called

condensation

. • These drops fall to the earth as rain, snow or hail.

Cirrus Composed of Ice= Pleasant Weather

Stratus Lower part of sky= light rain

• Cumulus Can signal= Violent Weather

Precipitation

• Water falls to the earth from clouds. Mainly as rain, but sometimes as snow and hail. • This is called

precipitation

.

Transpiration

• Transpiration is the process by which plants lose water out of their leaves.

• Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air. See Lab

Subsurface Runoff • How the water infiltrates (soaks) into the earth… • Will water go through a rock? • Will water go through sand?

Surface Runoff • is the water flow which occurs when soil is infiltrated to full capacity and excess water , from rain , snowmelt , or other sources flows over the land.

The Water Cycle Review • Your job is to go through 6 different water cycle sites. /teachers/adanny • Interact with the sites. Play around • Take notes / Take quizzes • Prepare for discussion on the top and worst sites that you went to. • Write down any interesting info that you find and then prepare your notes into VB questions.
