Glaciers are large masses of snow. These are formed when snow remains at one location for a very long time and turns into ice. They have ability to move, hence are called ‘rivers of ice’. The term ‘glacier’ originated from the French word glace (glah-SAY), which means ice. At present, they occupy about 10% of the world’s land. Most of them are located in the polar regions. Some of the glaciers move only a few centimetres a day while some can move about 50 metres a day. The fast-moving glaciers are called galloping glaciers.
