Glaciated valleys are U-shaped, non-glaciated valleys are V-shaped.
A fjord is a valley whose characteristic shape was created by a glacier, so it is a valley after it was glaciated.
A glaciated mountain valley typically has a U-shaped profile with steep, smooth walls and a flat bottom due to the scouring action of the glacier. In contrast, a mountain valley that was not glaciated usually has a V-shaped profile with more rugged and uneven walls, shaped primarily by flowing water and tectonic forces.
A glaciated mountain valley will likely have a U-shaped profile with a broad, flat floor and steep, often striated walls due to the erosion by the glacier. In contrast, a mountain valley that was not glaciated will typically have a V-shaped profile with a narrower, more gently sloping floor and less steep walls shaped primarily by the natural erosional processes of water and weathering.
It's called a "hanging valley". Many waterfalls occur at hanging valleys.

The mountainous regions that have been glaciated, the valleys are no longer narrow. The ice modifies the valley in three ways: the glacier widens, deepens, and straightens the valley.
A glacial valley filled with sea water is a fjord (pronounced ford)
At times, all the world's continents have been glaciated. A feature called 'inselberg' is often accepted as evidence of ancient glaciation unless some other explanation is more credible.

The general mountain range is called the Alps, of which many are high enough to be glaciated.
