Transcription: This is video footage of an iceberg floating on the ocean. Now remember why icebergs float. Water has a special property that its molecules are farther apart in its solid phase than they are in its liquid phase. As a result, solid water, ice, is less dense than water. As a result, ice floats on water. Now even though ice is less dense than water, the difference in density isn't great. As a result, when ice is floating, most of that ice actually is underwater. And you can see that in this video. The ice with the green hue is ice that's underwater. It's green because the water is mostly green. S ...
