Water Cycle
By: Mr. Danny
The Driving force of the Water
Cycle
Lake Erie has a huge role on the
Water Cycle
THE WATER CYCLE
4. Rain water
falls to form
rivers.

3. Water vapour
condenses to
form clouds

2. Water vapour is
carried up into the
air.

5. Rivers flow
into the sea
1. Water
evaporates

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.
