gravity. And the fact that ice behaves in a plastic (ductile, not brittle) fashion
a pulling motion causes a normal fault
With continents in their present positions, the till deposits do indicate erratic glacier motion. When continents are fitted together, they show much more streamlined motion of the glacier from the southern Africa and the Northern Australia outward.
A moving mountain glacier can carve a U-shaped valley. As the glacier moves downhill, it erodes the sides and bottom of the valley, creating a distinctive U-shaped cross-section. The glacier's immense weight and motion combined with erosion from the ice can shape the landform over time.
gravity
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 is a deep open crack in a glacier. It is formed when a magma chamber under a glacier causes melting and cracking and causes the glacier to slide into the ocean on the magma
There are three nouns. They are pressure, weight, and glacier.

what causes the motion of objects
motion
pressure is put on a glacier and causes a chunk of ice to float of on its own. This is a iceberg.
The ice moving from the glacier causes deposition by the movement made from the ice .
