A huge muss of ice fed by snow on a high mountain slowly sliding downhill before It starts melting is called Glacier. A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets.
