No, a glacier canyon is not a real glacier. A glacier canyon is a canyon formed by the movement of a glacier over time, carving out the landscape as it flows.
The rapid movement of a glacier is called a glacier surge. This sudden acceleration in movement can be caused by internal changes within the glacier, such as the release of stored meltwater or changes in the glacier's structure.
Two types of glacial erosion are plucking, where rocks and sediments are plucked from the bedrock by the moving glacier, and abrasion, where the glacier's movement causes it to scrape and polish the underlying bedrock.
The two types of glacial movement are basal sliding, which occurs when the entire glacier slides over the bedrock due to meltwater lubrication, and internal deformation, which involves the ice deforming and flowing like a viscous fluid under its own weight.
Glacier drift refers to the movement of a glacier across the landscape. This movement is caused by the force of gravity pulling the glacier downhill, as well as the internal deformation of the ice. Glaciers can move both slowly and rapidly, shaping the land and contributing to landform formation.
The end or outer margin of a glacier is called the glacier terminus. This is where the glacier ends and begins to melt or calve into the surrounding environment, such as a body of water or land. Changes in the glacier terminus are closely monitored by scientists to understand the health and movement of the glacier.

A ridge-like deposit of sediment at the edge of a glacier is called a "moraine." Moraines are formed from the accumulation of debris and sediment that has been pushed along by the glacier's movement. They can be classified into different types, such as terminal moraines, which mark the furthest advance of the glacier, and lateral moraines, which form along the sides of the glacier.
A confined glacier is a glacier that is confined by topography. For example, a glacier that forms on a mountain. Continental glaciers, by contrast, are not affected. The glaciers on Antarctica and Greenland are continental glaciers. The glaciers at Glacier Bay National Park, or on a mountain are confined glaciers.
The steady movement of the glacier over the centuries carved a valley through the landscape.
Glaciers primarily pluck resistant rock types such as granite, gneiss, and schist. These types of rocks are more likely to fracture and break when exposed to the stresses of glacial movement, allowing the glacier to pluck and transport them as it flows.
Glacier movement is primarily caused by the force of gravity pulling the ice downhill. As a glacier accumulates snow and ice, the weight of the ice causes it to slowly flow under its own mass. Additionally, meltwater at the base of the glacier can help reduce friction with the underlying bedrock, facilitating movement.
A crevasse slip is a type of glacier movement where the upper portion of the glacier slides down relative to the lower portion, causing the opening of crevasses or cracks on the surface. This movement can be triggered by internal glacier stress, changes in temperature, or the presence of water at the base of the glacier. Crevasse slips can pose risks to glacier travelers and mountaineers.
The two types of glacial movement are basal sliding, which occurs when the entire glacier slides over the bedrock due to meltwater lubrication, and internal deformation, which involves the ice deforming and flowing like a viscous fluid under its own weight.
The top part of a glacier is called the "glacier head" or "glacier accumulation zone." This area is where snow accumulates and compacts to form ice, feeding the glacier as it flows downward. The glacier head is crucial for the glacier's overall mass and movement, as it is where new material is added.
