context_page_description: A glacier is a large body of ice and snow. It forms because the snow in an area does not all melt in summer. Each winter, more snow is added. The weight of all the snow creates pressure. This pressure turns the lower parts of the snow into ice. After this happens for many years, the glacier will start growing large. It becomes so heavy that gravity causes the ice to move. It flows downwards like water but very slowly. A glacier only moves about 50 metres per year. New snowfalls replace the parts that flow away.
  Glaciers are the largest sources fresh water on Earth. The largest bodies of salt water are the Oceans
