Periods of rapid glacial movement are referred to as glacial surges. These events are characterized by a sudden increase in glacial velocity, resulting in the movement of large quantities of ice over short periods of time. Glacial surges can drastically reshape the landscape and contribute to changes in local ecosystems.
Post-glacial rebound (sometimes called continental rebound, glacial isostasy, glacial isostatic adjustment) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostasy.
They were created by glacial movement 10.000 years ago, in the last ice age.
Layers of glacial deposits are found at same place in sequence of rocksNote directions of glacial ice movement as indicated by striations or grooves in the rock
The continental shelves were developed in between the glacial periods as the ocean flowed over the continents forming shallow areas along the coasts. The continental shelves developed today were formed like 18000 years ago.
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.

[Glacial] flow
It was a continental drift .
U-shaped valleys are a result of alpine glacial movement. Bedrock is scoured and plucked by continental glaciers. A number of depositional features are a result of the movement and depositing of rock, sand and dust associated with glaciers.

crust
The reason is because of glacial desposits. The other reason is because of ice bergs and continental drift.

Glacial movement starts near the tops of mountains and ridges when the snowfall is heavy enough to start sliding downhill.
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.
