Where did the iceberg come from?
The iceberg that collided with the Titanic in the North Atlanticn most likely came from Greenland. Warm weather causes huge chunks of ice to break off Greenland's glaciers. These icebergs float south with the ocean current and eventually melt when they reach warmer waters.
The largest part of an iceberg is underwater only one-seventh to one-ninth is actually visible above the surface.
The biggest ones tower as much as 400 feet above the surface of the ocean.
