Basically, it's sliding on ice!

The main force that drives glacial flow is?

The main force that drives glacial flow is gravity. As snow accumulates and compresses into ice, it begins to flow downhill under the influence of gravity. This movement is further facilitated by the internal deformation and sliding of the ice over the landscape.


What are 3 types of glacier movement?

Three types of glacier movement are basal sliding, internal deformation, and flow. Basal sliding occurs when the glacier moves over a layer of meltwater at its base. Internal deformation involves the slow movement of ice crystals within the glacier. Flow refers to the overall movement of the glacier downslope due to gravity.


When does glacial movement begin?

Glacial movement begins when the weight of accumulating snow compresses into ice, causing it to flow under its own weight downhill. This typically happens when snowfall exceeds snowmelt for an extended period, allowing the ice to slowly begin its movement.


What does a sliding boundary look like?

A sliding boundary is a type of boundary that allows for relative motion between two plates, typically characterized by horizontal movement in opposite directions along the boundary. It often results in shearing or rubbing of rock material along the boundary, causing earthquakes. Deformation and striations on the rocks can be evidence of sliding boundaries.


What are the two types of glacial movement?

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.
