- A glacier is a large, flowing river of ice that usually moves very slowing.
- When a chunk of ice breaks off a glacier it is called “calving”.
- When that chunk of ice floats in the water it is called an iceberg.
- Most glaciers are found in the polar regions of the world.
- As the glaciers move across the ground they grind against the earth and carves out valleys.
- Large boulders can be frozen inside a glacier or pushed along by a glacier, and moved many miles before it is dropped.
- Glaciers cover about six million square miles of the Earth’s surface, but they are melting at an alarming rate.
- Between 10,000 to 15,000 icebergs are calved each year.
- There are animals, such a polar bears , seals and walruses that use icebergs as a place to rest and hunt for food.
- The Titanic sunk in the Atlantic Ocean because it hit a huge iceberg.
