Earth: Our Watery World

The Water Cycle

As the sun heats Earth’s liquid water, it becomes a gas. Later, this gas turns back to a liquid. It falls from the sky to the ground. This happens over and over. This is the water cycle.

What is my name?

The water in the pot boiled. The liquid water became a gas called water vapor.


Have you ever seen a puddle dry up? ____________ causes the liquid water to become water vapor. You can’t see it, but it’s there in the air.


Some mornings you see dew on plants. Water vapor in the air turned to liquid water. That is condensation at work.

The Water Planet

Water covers most of the Earth’s surface. This is why many people call Earth the water planet. Most of Earth’s water is in oceans. That water is salty. You can’t drink it. You can’t use it to grow plants. People need fresh water to drink, wash, and grow plants.

Planet Earth

The Water Planet

Most of Earth’s freshwater is frozen. It is in big sheets of ice. These are called glaciers. Earth does have some fresh water in rivers and lakes. There is even fresh water underground. People pump it up to the surface.
