Question

Why does ice float? How is this important to the thermal conditions on Earth? What are the differences between a solution and a mixture?

Answer 1

See this link.

Explanation:

Water is a remarkable substance with a very special property. In the solid phase it is LESS DENSE than the liquid phase. For most substances, the density of the liquid phase is LESS than the solid phase. And thus ice-bergs float on the surface of the ocean. If this were not the case, ice-bergs would sink in the Arctic, and the Antarctic......and quite likely the whole of the planet's oceans would eventually freeze from the bottom up.

For solution and a mixture.......that's another answer..........
