In Antarctica and the Arctic, the oceans freeze because the temperatures are so low.

Sea water, unlike fresh water continues to increase in density as its temperature decreases towards freezing point.

In fact, Antarctica contains 90% of all the ice on the earth and scientists have calculated that should all this ice melt, sea levels would rise by 60m causing worldwide flooding.��

An accumulation of sea ice can cause an iceberg which floats in the sea because it is less dense than water.

*Do you know?*

over 360 million square kilometres of the earth's surface area are covered by oceans and seas with the Pacific accounting for nearly 36% of the total.
