Transcript of Ice Sheets
They are found in the poles, only three remaining. They are in Greenland and in east and west Antarctica.
Where Ice Sheets are Found
They Form on land due to tens of hundreds of thousands of years of buildup of snow in cold regions of the Earth.
How Ice Sheets Form
They are slow-moving and do not change much season to season, and contain 98% of the worlds fresh water.
Ice Sheet Significance
Also it contains enough H20 for 70 m of sea level to rise.
The two Ice sheets on Earth today cover most of Greenland and Antarctica.
During the last Ice Age Ice sheets covered most of North America and Scandinavia
Ice Sheets are the size of continents (100s to 1,000s of km wide and 1-4 km thick!). They are called Ice Sheets because their width 1,000 times its thickness.
