If ice is less dense than water, how come icebergs are mostly submerged rather than only half?

Question

For example, most “full view” iceberg pictures I’ve seen, the iceberg has been vertically oriented – if ice is less dense than water, wouldn’t it at least be horizontal, with more than 10-15% of the mass visible above water?

Answer 1

The amount of ice exposed is directly related to how much less dense ice is vs liquid water. Ice is 10% less dense, therefore 10% of the ice sticks out of the water. The 90% that is underwater is the same mass as the water it is “pushing” out of the way.
