The glaciers, by slowly moving, dig into the land. Water from a source might begin to flow down that long hole caused by the glacier. This is how a glacier can make rivers.

As glaciers move, they can carve out deep depressions in the land called cirques. When the glacier retreats or melts, these cirques can become filled with water, forming lakes. Glaciers can also create moraines, which are piles of debris that dam up valleys, creating lakes behind them.

How was great lakes formed?
they where formed by giant rocks that fell form the sun
How did glaciers help form the great lakes st Lawrence lowlands?
Glaciation created a rolling landscape on the Great Lakes portion of the lowlands
How do glaciers form?
Glaciers form from the accumulation of snow when it exceeds the melting rate. The pressure of overlying snow causes it to change to solid ice. Eventually, gravity will cause it to move downward or outward from its own weight. Also, melting glaciers can cause glacial lakes to become too full of water and cause them to breach their natural boundaries, flooding the villages below.
What geological evidence do you have here in Alberta that glaciers once covered this province?
While rivers usually form 'V' shaped valleys, glaciers form 'U' shaped valleys. There could also be scratch marks made by the glaciers picking up boulders and scraping them over any exposed bedrock. When the glaciers melted, these rocks and debris were left as moraines, often damming the melt water to form lakes.
Which of these could be formed by glaciers?
Two interesting land forms that were formed by glaciers are called kettles and moraines. The kettles are sometimes very large and form large lakes. The moraines are hills that are found surrounding the kettles. Most are made of sand, gravel and small rocks, although they can have some rather large boulders in them.
Are the Great Lakes the world's largest group of freshwater lakes?
Yes. The Great Lakes are the largest body of freshwater lakes. They were formed by Glaciers that melted. The glaciers came from the north eventually melting to form the Great Lakes.
Did glacier movement form the Great Lakes or the Atlantic Ocean?
The Great Lakers were ultimately formed by glaciers. The Atlantic Ocean was not. It was formed by continental rifting. Glaciers could not form a whole new ocean basin like that.
How did the lakes in the Scandinavian countries and Finland form?
Glaciers.
Are the worlds largest group of freshwater lakes the great lakes?
Yes. The Great Lakes are the largest body of freshwater lakes. They were formed by Glaciers that melted. The glaciers came from the north eventually melting to form the Great Lakes.

How did glaciers help form the geography of the Midwest?
Glaciers helped form the geography of the Midwest because they created the 5 Great Lakes, while they were melting.
How does glacier erosion occur?
Glaciers can cause erosion because they move, though they do so slowly. As they move, often only a few inches a year, they scrape away and can gouge out the land, and then leave behind morass, which can be made up of left behind bits of rock or whatever happened to be in the glacier.
How did new Yorks finger lake form?
movement of glaciers
How did glaciers affect New England's Geography?
The glaciers helped to form many aspects of New England. This includes the mountains and the big lakes that are there.
Why don't glaciers form in Australia?
because austrailia has warm weather and warm weather does not cause glaciers to form
Why do glaciers cause erosion?
Glaciers cause erosion since they are in form of a block of snow which will melt and erode the land. This can be in form of abrasion, freeze-thaw or plucking.
Which agent of erosion was primarily responsible for forming the long U-shaped valleys in the Finger Lakes region of New York State?
ICE in the form of glaciers.
