Floating icebergs
Icebergs are thick masses of ice floating in the ocean. The reason why ice floats and is lighter than water is that a certain mass of ice occupies more space than the same mass of water. This is related to the characteristics of hydrogen bonds. This iceberg is floating off the Otago coastline.
