High Five Facts - Icebergs

The video provides an overview of icebergs, explaining their formation from glaciers and ice shelves, and their various shapes and sizes. It highlights that only a small portion of an iceberg is visible above water, with most of its mass submerged, posing potential dangers to ships. The age of icebergs can be thousands of years, offering insights into Earth's climate history. Icebergs are primarily found in polar regions but can travel far due to ocean currents. They play a crucial role in marine ecosystems by releasing nutrients that support marine life.

What is the process called when icebergs break off from glaciers?

• Erosion
