The rest of the planet’s water is
fresh water
. That means only
3 percent of the water is free of salt. And about two-thirds of the
fresh water is
solid ice
. That leaves just 1 percent of the planet’s
water as
liquid
fresh water.
Liquid fresh water is found in many places. A lot of the water is
underground. The rest of the fresh water is on the planet’s solid
surface. We see it in lakes and rivers. All the plants and animals on
the blue planet need water to stay alive. The people living there use
water in many ways. They use it for cooking, washing, drinking,
and growing food.
We have observed water in three states on the planet. It is the
only material found naturally on this planet in all three states.
Water can be solid ice, liquid water, and a
gas
called
water vapor
.
Water vapor
is in the air. There is more water in the air than
in all the rivers on the planet. We will find out more about water
vapor for our next report.
As you can see, water is an amazing material. It is in the ocean,
in lakes and rivers, in the ground, and in the air. It is everywhere.
The ocean makes up 97 percent of Earth’s water.
