A stream is most likely to form a narrow valley in areas with steep topography, such as mountainous or hilly regions. As the stream flows downhill, it erodes the surrounding rock and soil more rapidly, creating a V-shaped valley. This process is enhanced by factors like the geology of the area, which may include harder rock that resists erosion. Over time, the continuous flow of water carves out a narrow and steep-sided valley.
A narrow V-shaped valley.
A stream valley is usually 'V' shaped, formed by erosion from a stream. A glacial valley is usually 'U' shaped, formed by the action of a glacier.
Yosemite Valley in California is a well-known example of a v-shaped valley. It was formed by the erosive action of glaciers over thousands of years, resulting in steep valley walls that come together to form a V shape.

These long narrow glaciers are called valley glaciers. They form when snow accumulates in a valley and slowly turns into ice, flowing downhill under the force of gravity. Valley glaciers are often found between mountains in regions like the Alps and the Andes.
Streams are formed when water cuts through the ground. This water wears away a path which then turns into a stream.
Contour lines will bend and point upstream to form a "V" shape when crossing a stream valley on a topographic map. The V-shape indicates the direction of the stream flow and shows the gradual slope of the valley.
A braided stream is a stream that has small channel capacity with respect to its sediment supply. Basically, there is not sufficient room within the stream valley to deposit all of the sediment and therefore, small islands of sediment form within the stream giving it a braided appearance. Braided streams generally occur at high gradients.

V-shaped valleys are typically formed by the erosive force of a river or stream. They are characterized by steep walls and a narrow channel, with the V-shape often indicating the down-cutting erosion process of the water over time. These valleys often form in mountainous or hilly regions where there is significant vertical erosion by the flowing water.
