An ice age is a time when Earth's climate becomes much colder than normal and huge sheets of ice cover large parts of the land. These enormous sheets of ice are called glaciers. A glacier is a thick mass of ice that forms when snow piles up year after year and gets packed down into solid ice. Throughout Earth's history, there have been several ice ages.

During the most recent ice age, which ended about 10,000 years ago, glaciers covered much of North America, Europe, and Asia. Some of these ice sheets were more than a mile thick! Glacial movement happens when glaciers become so heavy that they slowly slide across the land, kind of like a very slow river of ice. As glaciers moved, they acted like giant bulldozers. They scraped the land beneath them, carved deep valleys, and pushed huge piles of rock and soil ahead of them.

When the climate warmed up and the glaciers melted, they left behind completely changed landscapes. The melting ice created new lakes, formed hills made of the rocks and soil the glaciers had pushed, and left behind wide valleys. Many familiar features we see today were shaped by glaciers. The Great Lakes, many valleys in the northern United States, and rounded hills were all created by glacial activity. This evidence of ice ages shows us that Earth's climate and surface have changed many times throughout history.

Interesting Fact: During the last ice age, so much water was frozen in glaciers that the ocean level was about 400 feet lower than it is today. You could have walked from Asia to North America across a land bridge that is now underwater!
