Are you drinking the
same water a dinosaur
drank?
Could you be drinking
the same water a saber
tooth tiger lapped up?
Water on earth moves in a
continuous cycle. This is called
THE WATER CYCLE. There is
about the same amount of
water on earth now that there
was when the dinosaurs
roamed our planet.
What do you think? Is
the water we have on
earth today the same
water that was here
millions of years ago?

What drives the water cycle?
How does liquid water change into vapor
that can go up into the atmosphere?
•Evaporation
90% •Transpiration
What percent of the water in the
atmosphere comes from
evaporation?
10%
Evaporation
• Evaporation is the
process in which water
is turned from its liquid
form to its vapor form
• Does this require
energy?
Transpiration is the process by which plants return
water to the atmosphere. After absorbing water from
the ground, plants release water through their leaves.
Transpiration helps plants stay cool, in the same way
perspiration keeps humans and animals cool.
Condensation
• Condensation is when
water changes from its
vapor form to its liquid
form
• Does this require
energy?
What part does condensation play in
the water cycle?
What happens when clouds get too heavy?
Precipitation
Types of Precipitation
Condensation
The movement through plants
The Clouds form
Transpiration
Precipitation
The rain falls
Evaporation
The vapor rises
Last Stage of Water Cycle
Water carried to
ocean by
streams, rivers
and ground water
