How do icebergs form and where do they go?
Icebergs form when chunks of ice calve, or break off, from glaciers, ice shelves, or a larger iceberg. Icebergs travel with the ocean, sometimes smashing up against the shore or getting caught in shallow waters.
When an iceberg reaches warm waters, the new climate attacks it from all sides. On the iceberg surface, warm air melts snow and ice into pools called melt ponds that can trickle through the iceberg and widen cracks. At the same time, warm water laps at the iceberg edges, melting the ice and causing chunks of ice to break off. On the underside, warmer waters melt the iceberg from the bottom up.

Exactly how big are normal ice-bergs?
Only about a quarter of the ice-berg you actually see on top of the water! That's huge! If we were to go under the water, the ice-berg would be at least 3 times the size of the ice-berg you see above water!
Have a look at this wonderful picture to show an example!
Did you know that the famous Titanic went down due to an ice-berg! Thats a pretty cool fact right! The reason the Titanic crashed was because it couldn't actually see the ice-berg because it was underwater!
Why are Ice-bergs Important?
Icebergs can also serve as tools for scientists, who study them to learn more about climate and ocean processes.
Why do scientists study icebergs?
Scientists have noticed that the way icebergs break up when they reach warmer waters reflects the disinagration of Antarctic ice shelves!
