HOW GLACIERS FORM AND MOVE!

WHAT IS A GLACIER?

• A glacier is a large mass of ice that moves slowly over land.
• There are two types of glaciers *continental and valley glaciers.

FORMING

• Glaciers form only where there is a lot of snow.
• The snow melts.
• When depth of snow reaches more than 30 to 40 meters gravity begins to pull glacier downhill

HOW VALLY GLACIERS MOVE

• Valley glaciers flow at a rate of a few centimeters to meters per day
• Sometimes slides down more quickly than a surge.

HOW CONTINENTAL GLACIERS MOVE

• Continental glaciers spread out like a pancake batter in a way.
• Most of the time they don't move
• They cover a lot of land at one time.

FACTS

• Glaciers have gotten smaller over time
• Glaciers can cause erosion
• Continental glaciers a the biggest
• Valley glaciers are smaller
• The movie Ice Age shows mostly continental glaciers
