Glaciers

Glaciers Topic 1 Glaciers 1.What is a Glacier' A glacier is a big moving mass of ice; it is formed in high mountains or high latitudes where the amount of snowfall is higher than the melting rate of snow. 2. How do glaciers differ from ice shelves, icebergs and sea ice' Glaciers are huge and they also have a granular structure. Glaciers change the shape and the land though they’re slow but significant movement. Ice shelves are floating masses of ice that are attached on at least one edge of the coast. Sea ice is seasonal ice during, during the summer there is less than in the winter. Icebergs are huge chucks of glaciers; they are also seasonal so they change with the climate. 3. How much glacier ice is on earth' There is over fifteen million square kilometers of glaciers covering the earth’s surface. 4. How do glaciers form' Glaciers are formed when there is more snowfall than evaporation. If the snow from the winter does not melt during the summer the next winter will snow on top of the pervious winters snow, which keeps building up creating glaciers. 5.
