Document Summary

Continental glacieirs: glaciers that cover large areas of the surface are called continental glaciers. Today there are only two continental glaciers, antarctica and greenland. Approximately 70% of all freshwater is contained in the polar ice caps and greenland. They hold so much of the earth"s fresh (cid:449)ater that if they melted (cid:272)ompletely sea le(cid:448)el (cid:449)ould rise (cid:271)y o(cid:448)er 70 m: however, at one time not long ago (15,000-20,000 years ago) glaciers covered much of. North america and especially the midwest and indiana. Glaciers plowed over indiana from two directions, the north from lake michigan and the northeast from lake erie. These glaciers left very distinctful markings on the surface that can be used to trace their beginnings and progress. Glaciers in indiana: from about 12,000 to 2 million years ago, great, continental glaciers covered much of. These glacial ice sheets were enormous with some being miles thick.
