Question

Why does ice melt?And how does it melt?

Answer 1

Energy to melt ice can come from sources besides direct solar energy. Water that is under the ice and that has a temperature above the freezing point causes the bottom surface of the ice to melt. Warm surface waters cause the edges of the ice to melt, particularly in leads and polynyas.

Answer 2

Answer: Ice melts when heat energy causes molecules to break the hydrogen bonds between molecules to form liquid water.
