a glacier valley forms from the pieces of ice that the glacier leaves behind when it broken down thats all i realy know
Fiords and glacial lakes
A 'U' shaped valley indicates glacial erosion.
If it is inundated by the sea it is called a "Fjord", if not is just a glacial valley.
A glacial trough is a U-shaped valley carved out by a glacier as it moves downhill. It forms through a process called glacial erosion where the glacier scours and deepens the valley over time by plucking and grinding the bedrock beneath it. The vast weight and movement of the glacier cause it to scrape and shape the landscape into a distinctive U-shaped trough.

A U-Shaped Valley is formed by glacial erosion.
A bowl-shaped depression at the head of a glacial valley is called a cirque or a corrie. It is typically formed by the erosion of a glacier.
A stream valley typically has a V-shape, while a glacial valley has a U-shape. This difference in shape is due to the different erosional processes involved. Stream valleys are eroded mainly by flowing water, while glacial valleys are shaped by the movement of glaciers that scrape and pluck rock and sediment.
A U-shaped valley is considered a glacial landform resulting from the erosive action of a glacier. It is classified as a destructive force as the glacier carves and deepens the valley by plucking, abrasion, and glacial erosion.
