The Water Cycle
What is it and how does it work?
The Water Cycle
Condensation
Water Vapor
Precipitation
Evaporation
Collection
Water
The water cycle begins with water. Water is found in many
places. A few of them are as follows:
Lakes, rivers, oceans, ponds, puddles, reservoirs, and
many other places.
The next stage is evaporation. This is a process where the
water is heated and turned into a water vapor. The sun is the
main heat source for this process.
The evaporation of water
from those parts of plants
that are outside the earth,
especially leaves but also
stems, flowers and fruits is
called transpiration. The
amount of water lost by a
plant depends on its size,
light intensity,
temperature, humidity, and
other factors
The next stage is condensation. This is where warm and cold air
collide and form ice crystals that condense and form droplets of water.
These water droplets eventually become too heavy and begin to fall in
the form of precipitation.
The next stage is Precipitation. This is water falling to the
earth in the form of snow, hail, rain or sleet.
What happens with rain?
- It falls over mountains.
Water flows downhill from
high places like
mountains and hills into
streams, then rivers, and
finally into the ocean. We
call that run-off
- Infiltration is the process
where water seeps into
the ground. Just like a
sponge soaks up water,
so does the soil. When
it rains, some of the
water will infiltrate or
soak into the soil.
The next stage is percolation (also called “groundwater flow
or groundwater discharge). Water moves downward from
surface water to groundwater The water seeps through the
soil and ends up in the water table. It then flows into the
streams, lakes, oceans, and other bodies of water. The
process is then repeated again and again.
