BBC - Earth The Biography Part3: Ice (2007) UNRATED BRRip 720p x264 AAC-DiVERSiTY.rar


After explaining how snow, crystallized frozen water, turns into ice, we examine it's major role in shaping the earth's surface. Glaciers exert enormous forces, capable of extreme erosion, and often faster then it appears. The polar caps are entirely ice-covered, even permanently hiding Antarctica's island archipelago and world top 10-lake. Climate change is largely about ice advance or retreat, which also vastly contributes to currents modification.
