EXPLAIN GLACIER
The glacier is a large mass of ice that forms from the accumulation of snow and moving downward due to gravity, yawning or melt. Drifts of snow gradually becomes very thick, so it would form a layer of ice on the surface of the earth.
Thick layer of frost into plastically material and has a huge gravitational force, so that the ice moves slowly spread to a wider area or down through the mountain slope. Move ice mass is what is called a glacier.
Vast ice sheet that started the Ice Age in North America is referred to as ‘continental glaciers’. The ice sheet thickness is estimated to reach 15,000 feet (4.5 km) from its center. This immense glaciers may have formed and melted at least four times during the Ice Age. The glacier is ice flow that comes from the snow.
Or Ice Age glacial period that took place in other parts of the world have not had time to melt. For example, a large island Greenland (Greenland) is still covered by continental glaciers, including in the outskirts of the largest island in the world. So, the reason why the Earth still has a glacier in certain regions of the Earth are due to the snow in these areas do not have time to melt since the Ice Age.
