Document Summary
Water stored as ice in glaciers came from the oceans. Episodes of glaciation ended about 10,000 years ago. Rock records have evidence of older glaciations extending back to 2. 8 billion years ago. A glacier is a large, long-lasting mass of ice, formed on land, that moves downslope under the influence of gravity: develops as snow is compacted and recrystallized. There are 2 types of glaciated terrain: both change landscape: alpine glaciation, found on mountainous regions, continental glaciation, exists where a large part of a continent is covered by glacial ice. The theory of glacial ages: (cid:1005)8(cid:1004)(cid:1004)"s: hypothesis of past extensive continental glaciation of europe was proposed by louis. Ontario, and valley glaciers shaped mountain valleys of banff and labrador. In higher altitudes: climate change is causing very rapid melting of these ice masses, glaciation is most extensive in polar regions, where little melting takes place at any time of the year.
