HOW BIG IS AN ICEBERG?
Most of the iceberg is hidden under the surface of the water. The iceberg in the picture is maybe 900 metres high. What sticks out of the water is only 100 metres.
Icebergs of that size may reach a volume of 1.5 cubic kilometres.
Put an ice cube in a glass of water. How big a part is visible above the surface of the water?
Put a mark on the water level and let the ice cube melt. Does the water level fall or rise or is it unchanged?
When the iceberg floats through the Icefjord it melts from below. It changes form and loses the balance.
Why can an iceberg turn around suddenly?
