The Water Cycle
Water has been around
for MANY years
Water gets recycled over
and over again

What is the Water Cycle?

“Transpiration”
the evaporation of water from plants
“Transpiration”
Do plants really sweat?
Plants like me release water
to supply photosynthesis,
bring minerals up from the
roots, and cool ourselves off.
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.
“Evaporation”
The conversion of water from a liquid to a gas
Solar energy drives evaporation of water from the ocean.
The evaporated water changes from a liquid form into
water vapor a gaseous form.
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”
The transformation of water vapor back into liquid water by cooling
Evaporated water is warmed and rises into the air where
it eventually cools and condenses to form 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.
“Precipitation”
Rain, hail, or snow falling from the clouds
due to the condensation of water
When clouds become very heavy with
condensed
water, the water
is released
With enough
condensed
water,
you get rain!
in the form of rain, hail, or snow.
Precipitation
• Water falls to the earth from clouds. Mainly as
rain, but sometimes as snow and hail.
• This is called precipitation.
“Accumulation”
The collection of precipitation into rivers, lakes, and oceans.
This completes the water cycle!
