The Formation and Types of Glaciers

The video explains that snow is frozen water, which melts as the weather warms. In some regions, snow compresses into glaciers, which are large masses of moving ice and snow. Valley glaciers form in high mountain valleys, while continental glaciers, found at the poles, are vast and can be over 4 kilometers thick, holding large amounts of frozen fresh water.

What happens to snow as the weather warms?

• It melts into liquid water.

• It evaporates.

• It turns into ice.

• It remains frozen.

What are glaciers primarily composed of?

• Air and dust

• Ice and snow

• Sand and rocks

• Water and mud

Where are Valley Glaciers typically found?

• In deserts

• In urban areas

• In tropical forests

• In high mountain valleys

What is a key characteristic of Continental Glaciers?

• They cover large areas and hold vast amounts of frozen water.

• They are small and thin.

• They are found in deserts.

• They are only found in tropical regions.

How thick can Continental Glaciers be?

• Only a few meters thick

• Exactly 1 mile thick

• Over 4 kilometers or 2 1/2 miles thick

• Less than 1 kilometer thick
