Ice on Earth

Not all of Earth's water is liquid. Water can be solid, too! Solid water is called ice.

Some places on Earth, such as the North and South Poles, are very cold. Because of how cold it is, the water is frozen year-round at the North and South Poles. The water there forms ice.

Glaciers

Glaciers are solid pieces of ice that are made from fallen snow that has been packed down over many years.

It can take thousands of years for a massive glacier to form.

Most glaciers are found in Antarctica and Greenland, but they can be found all over the world!

There are also other landforms that exist underwater.
