Water Cycle
The Hydrologic Cycle
a.k.a. hydrologic cycle
•You have 8
min. to draw
and label the
water cycle.
I’ve got
the
power!
Evaporation
• Heat energy from
the sun causes
water in puddles,
streams, rivers,
seas, oceans or
lakes to change
from a liquid to
water vapor (a
gas).
• This is called
evaporation.
•Eventually the
vapor rises
into the air and
collects in
clouds.
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.
Condensation
• As water vapor
rises and cools, it This is called
collects around condensation.
dust particles
(or condenses)
and forms
clouds.Water
vapor (a gas)
becomes liquid
again.
Precipitation
• When clouds are saturated
gravity pulls the water to the
earth. Mainly as rain, but
sometimes as snow, sleet, and
hail.
•This is
called
precipitation.
2 types of Run Off
• Surface run off: movement of
water on Earth’s surface to
collect in rivers, streams,
lakes and oceans.
• Subsurface run off: movement
of water beneath the Earth’s
surface that eventually
collects in aquifers and
springs.
• Infiltration occurs when the water
moves from the surface into the soil.
• Then water percolates down through the
soil. The rate of percolation depends on
the type of soil.
Accumulation
• a.k.a. collection
• Water collects in rivers, lakes,
streams, and the ocean.
