WHAT IS A GLACIER?
Glaciers and
the gigantic ice sheet that covers most of the country are a usual sight in Greenland.
A lot of glaciers are rivers of ice that emerge from the ice sheet. When the
ice begins to move, it is a glacier, but when the ice breaks free or falls into
the water it is an iceberg.
Glaciers move because of the force of gravity and meltwater (it acts as a sort of lubricant). The movement of glaciers depends on a number of different climatic factors, over a longer period.

A lot of
people believe that climate change is an important factor in connection with
the fact that glaciers all over the world are withdrawing.
Glaciers are jagged in their contours in contrast to the ice sheet, which is flat in the middle. The ice is moving at different speeds, because of it, glacier crevasses are occurred. It creates attractive pinnacles that rise into the air. In the other hand, it also creates treacherous crevasses that can be concealed by snow. Because of it, you should always go up onto a glacier with an authorized guide.
