Inlandsis Ice-Stream ( Greenland )

"This we know, the Earth does not belong to man, man belongs to the Earth. All things are connected like the blood which unites one family...Whatever befalls the Earth, befalls the sons of the Earth. Man did not weave the web of life; he is merely a strand in it. Whatever he does to the web, he does to himself"

Chief SEATTLE, 1854. (1786-1866)

Inlandsis or ice sheet is a mass of glacier, greater than 50 000 km² (19 305 miles).
The only current inlandsis are Greenland and Antarctic. The Greenland ice cap is the only relic of the last continental glaciation.

Although the surface is cold, the base of an ice sheet is generally warmer, in places it melts and the melt-water lubricates the ice sheet so that it flows more rapidly. This process produces fast-flowing channels in the ice sheet - these are ice streams.

• Did you know?
  The Greenland ice sheet occupies about 82% of the surface of Greenland, and if melted would cause sea levels to rise by 7.2 metres.
