Water
Why is it important?
Water
Earth is 75% water
More plants and animals live in water than on land
People need to drink water to stay healthy
We use it to cook
Protects our organs
Carries oxygen and other nutrients to our cells
It’s the start of The Water Cycle, a major driving force on our planet
We use it for recreation
To transport things – ships and cargo
Assists in plant growth
Controls body and planet temperature
Used to clean things – dishes and our bodies
Rids of body wastes
Exists in three states – solid, liquid and gas and all are beneficial to humans
The Water Cycle
Describes how water moves between the
earth’s surface and the atmosphere.
And how does it do that?
It rains!
How does it rain?
1. The sun heats the ocean.
2. Water evaporates forming water vapor in the air.
3. The vapors cool and condense to become raindrops,
which form clouds.
4. These raindrops fall to the
ground.
5. The rain flows back into
the waters.
6. The water sinks into the
soil to collect underground.
The cycle starts all over again.
It’s The Water Cycle!
Evaporation
The process of becoming a vapor.
1.The sun heats the ocean
2.Water evaporates from warm
air and low pressure areas to
form water vapor in the air.
High Energy:
Evaporating
Medium Energy:
Pulled back into water
Lower Energy:
Remain as liquid
Condensation
to transform from a gaseous state into a liquid state
3. The vapors cool in cold air and condense to become
raindrops, which form clouds.
Precipitation
the falling of any form of water (rain, snow, hail, sleet or mist) to the ground
What might cause the
rain to fall?
A. The ground pulls
them down.
B. The raindrops become
too heavy for the
atmosphere.
C. The clouds push the
drops out.
D. The air does not want
the drops anymore
4. These raindrops fall to the ground.
Runoff
any precipitation on an area that is not absorbed, but instead flows away
from that area
5. The rain flows back into the waters
and down areas of land.
Percolation
the movement of water through soil
6. The water sinks into the soil
to collect underground.
Infiltration
Percolation
Infiltration = percolation
