The Water Cycle
By: Antwan Horton
What is the water cycle?
The water cycle describes the continuous movement of water on,
above and below the surface of the Earth
There are seven main stages of
the water cycle.
Step 1: Evaporation
Step 2: Condensation
Step 3: Sublimation
Step 4: Precipitation
Step 5: Transpiration
Step 6: Runoff
Step 7: Infiltration
The process of turning liquid to gas.
The conversion of a vapor or gas to a liquid.
The process of going from a solid gas without ever
becoming a liquid.
Example: Most often used to describe the process of
snow and ice changing into water vapor in the air without
first melting into water.
This is when water is falling out of the sky, this could
be rain, drizzle, snow, sleet, hail or something rarer
Transpiration is the evaporation
of water from plants.
Transpiration is very important for
maintaining moisture conditions
in the environment. As much as
10 percent of the moisture in the
Earth’s atmosphere is from
transpiration of water by plants.
Runoff is precipitation that did not
get (infiltrated) absorbed into the
soil or did not evaporate, and
therefore, made its way from the
ground surface into places that
water collect. Runoff causes erosion
and also carry chemicals and
substances on the ground surface
along to the rivers where the water
Infiltration is the movement of water into the
ground from the surface.
Why is the water cycle important?
• The water cycle makes sure there is never ending water for all living
• It regulates weather patterns on the Earth.
• If water didn’t recycle itself, we could run out of clean water.
• It is important because it is how water reaches plants, animals and
• Water is needed for agriculture, food processing, and manufacturing
What happens if the water cycle is
The water cycle brings water to everywhere on land, and is
the reason that we have rain, snow, streams, and all other
kinds of precipitation. Stopping it would cause an endless
drought. No water flow in lakes would cause overgrowth,
killing many species of fish and other lake wildlife.
What if there were no trees?
Trees provide maintenance of the water
cycle. They draw up water from their roots,
which are then released into the
atmosphere. However, a large part of the
water that travels through the ecosystem of
rainforests, for instance, remains inside the
plants. Although, when these trees are cut
down, it causes for the climate to become
drier in that specific area. The groundwater
tables on the other hand, are affected and
soon get exhausted.
