Ice
is constantly on the move. The great weight of the accumulating
ice and snow causes ice to spread slowly outwards toward the
edges of the ice cap. Nearing the sea, the ice is gradually
forced through gaps between the coastal mountains, scouring
a pathway through in the form of glaciers. Once the glaciers
reach the sea, they break off into tremendous icebergs that
crash into the water and drift away. Thus the snow that falls
on Greenland slowly but surely finds its way to the sea, where
it eventually melts and returns to the never-ending water
cycle--perhaps to fall once again as rain or snow on Greenland.
