Have you ever heard someone say “H2O”
when they’re talking about water? Do you
know why? I’ll give you a hint. It’s not
internet slang.

The Earth is sometimes called “The water
planet” because its surface is covered
mostly by water.
<image>
How does water stay on our planet?
Where do we get our water? We’ll answer
these and other questions about water in
this lesson.

The water on Earth is as old as the Earth
itself. The water cycle keeps all the water
going around and around. It never leaves,
and it never runs out.

As all the water on our planet goes
through the water cycle phases, we don’t
gain or lose any. Let’s take a look at what
keeps this cycle moving.

Most of the water on Earth is found in the
oceans, which covers over half of the
Earth’s surface.

Evaporation happens when the water
molecules on the surface change to gas
and become part of the air around it.
<image>
When a water molecule evaporates from
the ocean surface, the next molecule
moves to the surface where it, too, is
exposed to the ocean air and evaporates.

As the water evaporates, the salt in the
oceans is left behind because the salt
molecules are too heavy to evaporate.

As water molecules evaporate from the
ocean, they enter the air as water vapor,
which makes the air more humid.

Water vapor is water in the form of a gas.
It is invisible and can move quickly
because of the wind.

If you’ve ever had a humidifier or vaporizer
in your home it does the same thing.

When you boil water, the steam that rises
above the pot is water vapor.

Wind pushes the water vapor up into the
sky to colder air. The water molecules
move closer together, or condense,
around small dust particles to form clouds.
<image-fade previous white cloud to this
dark cloud>
A cloud is actually made of liquid water
molecules that move and stick together.
That’s how we can tell when it’s about to
rain!

Question C
Stem: What forms when evaporated water molecules in the air condense around small
dust particles?

As more and more water molecules
condense into the cloud, it becomes
heavy.
<image>
Once the cloud becomes heavy, it
releases the water molecules in the form
of precipitation. Down here on the surface
of the planet, we get wet!

<image>
There are many types of precipitation.
http://commons.wikimedia.org/wiki/File:Wa The way the water molecules come down
ll_cloud_with_lightning_-_NOAA.jpg
depends on the temperature of the air.
Rain and drizzle are liquid forms. Snow,
sleet, and hail are freezing forms.
<image>
The water molecules continue the water
cycle as they fall back to Earth. When they
reach the surface they fall back into the
bodies of water or soak into the ground.

Question D
Stem: How do water molecules enter back into the water cycle after clouds have formed?

A water molecule is the smallest unit that
is still water. If you looked at the tiniest
pieces that make up the ocean or a pond,
you would see these water molecules.
http://pixabay.com/en/h2o-water-molecule580992/
<image>
Water exists in different phases of matter
based on the way the molecules behave,
and how close together or far apart they
are.

When water freezes, it expands and
becomes a solid, and the atoms move
farther apart. That’s why ice floats!

This property of the water molecule is very
important to us. Imagine what would
happen if all the glaciers sunk!

The sun shines directly over the ocean
with strong and bright rays. Because there
are no trees or mountains to block the
sun, it receives a full day of sunshine.
<image>
http://www.morguefile.com/archive/display

The top level of the ocean absorbs and
holds more of the sun’s energy than the
rest of the Earth’s atmosphere.

This strong energy from the sun can
cause many water molecules to evaporate
even faster than normal.

This is why the air feels so humid and
moist and might look hazy when you are
at the beach.

ocean?

A.
B.

Water molecules that evaporate and enter
the air affect our weather patterns.

Even if water molecules evaporated from
the ocean, the land on Earth could affect
the weather that we experience.
<image>

If a cloud forms over the ocean, it might
travel to a mountain, moving the moist air
upward, to cooler air. The water molecules
cool and precipitation occurs.
<image>
The temperature of the air determines the
precipitation that comes from the cloud. If
the air is warmer than freezing, it will be
rain.

Otherwise it could be sleet, hail, or snow.

Much of the weather that we experience
happens because of the evaporating water
molecules from the ocean.
<image>
Most of the rain we see on land was
evaporated from water molecules in the
ocean, and carried to land by clouds.

Clouds hold the water vapor until they
become too heavy. When they can’t hold
any more water vapor, we experience
precipitation.
<image>
If the air temperature is freezing, our
precipitation will be one of the frozen
forms. If we have warmer air, we will get
rain!
