Question

Ice floats in water because it is

Answer 1

Less dense than water. Ice is frozen water, and water, I think, expands on cooling and freezing (it's a very unusual property of water). When placed in water, ice will displace a volume of water equal to its own weight, which is how it floats. Most of the ice will be under the water, though, and in the case of icebergs in the sea, you won't be able to see the full size of the thing. That was part of the problem that the Titanic ship had. It got a very big hole in it from an iceberg, and the hole was below the ships water line. End of Titanic. Excepting that under the sea, the ice may be warming and melting. This makes the iceberg become to heavy, and eventually the thing tips over. I'm told that its a very spectacular sight seeing an iceberg flip over.
