u shaped valley..
Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
A glacial valley is formed by the movement of glaciers, which carve out deep U-shaped valleys with steep sides and flat bottoms. A river valley, on the other hand, is formed by the erosion of flowing water over time, resulting in V-shaped valleys with narrower bottoms and less steep sides. Glacial valleys generally have a more pronounced U-shape and are wider compared to river valleys.
Bored or U-shaped valleys in mountain river valleys are primarily formed by glacial erosion. As glaciers advance, they carve out the landscape, widening and deepening valleys through the process of abrasion and plucking. This results in the characteristic U-shape, contrasting with V-shaped valleys formed by river erosion. Over time, the immense weight and movement of the glacier reshape the terrain, leading to the distinctive valley profile.

V-valley refers to a type of valley on a topographic map that has a V-shaped profile, typically formed by erosion from a river or stream. U-valley refers to a valley with a U-shaped profile, typically formed by glacial erosion. V-valleys are more narrow and have steeper sides compared to U-valleys.
The different types of river valleys include V-shaped valleys, U-shaped valleys, and canyon valleys. V-shaped valleys are typically narrow with steep sides, carved by erosion from a river. U-shaped valleys are wider and have more gradual slopes, formed by glaciers. Canyon valleys are deep and narrow with steep sides, often formed by a combination of tectonic activity and erosion.
You can transform a v-shaped valley into a u-shaped valley by a glacier.

A stream-carved valley typically has a V-shape with a narrower and deeper profile due to the erosive force of flowing water. In contrast, a glacial-carved valley has a U-shape with a wider and shallower profile due to the movement of glaciers scooping out the landscape.
A 'V' shaped valley has been formed by a stream or river. A 'U' shaped valley has been formed by the action of a glacier. Therefore, should a glacier form in the mountains, the ice, pushed downhill by the weight of fresh snow constantly being added high above, will gouge out the 'V' shaped river valley and form the 'U' shaped glacial valley.

A U-shaped valley begins as a V-shaped river valley. If the temperature is low enough, a glacier (river of ice) forms inside the valley. As the glacier slowly moves, it scours the valley floor when the temperature rises and the glaciers melts away, a U-shaped valley is left behind.
