Question

Why does ice float in the water?

Answer 1

The water, which is less dense than the rocks, will float. As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid frozen state than in their liquid state. Water is different because of hydrogen bonding.

Answer 2

due to the weight of ice.
the lighter the weight, the lesser the density and the object will float
