Glacier speed is not constant across the glacier. The top half of the glacier moves faster than the bottom, presumably because of friction. The sides also flow slower than the middle, also because of friction. The middle of the glacier at the equilibrium line flows fastest, the head and terminus flow slower. Above the equilibrium line the glacier grows faster than it melts; this is called the accumulation zone. Below the equilibrium line, the glacier melts faster than it grows; this is called the ablation zone.
There are continental glaciers in and around the Arctic and Antarctic circles, and covering parts of Greenland and other polar region islands.
Glaciers in North America are primarily found in Alaska and the Pacific Northwest region of the United States, particularly in states like Washington and Montana. Glacier National Park in Montana is home to several prominent glaciers. There are also glaciers in parts of Canada, such as the Canadian Rockies and the Coast Mountains in British Columbia.
Glaciers in Canada are primarily found in the northern territories of Yukon, Northwest Territories, and Nunavut, as well as in the western province of British Columbia. Some glaciers can also be found in the eastern province of Newfoundland and Labrador. These glaciers play a significant role in shaping Canada's landscapes.
A cirque glacier is a small glacier that occupies a cirque or rests against the headwall of a cirque. A cirque is a deep, horseshoe-shaped hollow with steep walls which was created by erosive activity of glaciers.
Glaciers have significantly shaped Ohio's landscape, resulting in features like the Great Lakes, which were formed by glacial erosion and deposition. The state also boasts numerous glacial till plains, which are fertile areas created from the sediments left behind as glaciers retreated. Additionally, the formation of moraines, or ridges of debris, can be observed in various parts of Ohio, marking the former positions of glaciers.
2/3 of the earth is covered by glaciers
Southern Ohio and even parts of Missouri.
The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.
during the ice age
2/3 of the earth is covered by glaciers
During the Pleistocene ice age, glaciers covered large parts of North America, Europe, and Asia. These glaciers were extensive and had a significant impact on the landscape and climate of these continents.

Glaciers can be found in many different parts of Canada. For a few examples, some can be found in the mountains in British Columbia and also on the islands of the Arctic Archipelago.
