Glaciers on average only move a few inches per day. Some don't move at all. The Jakobshavn Isbræ glacier in Greenland moves 20 to 30 meters a day, while the Byrd Glacier in Antarctica, the biggest in the world, moves 2 - 3 meters a day.
Some may move more quickly if they are affected by seismic invents that may happen near its location.
Depending on when it was formed, the size and speed it is moving it could be either an Avalanche or Glacier. If it is an incredibly old, slow moving, large, ice mass it is likely a Glacier; however if it is a quickly moving, small (relatively), ice mass it is an Avalanche.

A slow-moving conveyor belt system could compare to a glacier. Both gradually move material over long distances, shaping the landscape as they go. They share similarities in their slow, continuous progress and their ability to drastically change the environment over time.
A glacier moving down a mountain is an example of something that moves very slowly. It can take many years for a glacier to travel a short distance due to its slow rate of movement.

A slow melting glacier
A slow-moving river of ice is called a glacier. Glaciers form when snow accumulates and compresses into ice over time, flowing downhill under the force of gravity. Glaciers can carve out valleys, carry debris, and shape the landscape as they move.
A slow moving river of ice is known as a glacier. Glaciers form over time as layers of snow accumulate and compress into ice. Glaciers flow downhill under the force of gravity, shaping the landscape as they move.
A continental glacier can move in all directions and a valley glacier can move in a surge. :)

A slow-moving body of ice is called a glacier. Glaciers form over time as snow accumulates and compacts into ice. They can carve out valleys, shape the landscape, and contribute to rising sea levels as they melt.
