A Glacier is a mass of ice and snow, which is continuously moving to lower ground or, if afloat, continuously spreading. This flowing movement happens due to its weight, which causes the bottom layer of ice to behave plastically, and can as a result, flow from the middle of the ice sheet and move slowly towards the sea.
The biggest glacier in the world is in Antarctica. The Lambert Glacier is 515 km long and over 50 km wide. It moves along at a rate of about 2.5 cm a day.
