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.

What is the best way to describe the shape of a glacial valley?
A glacial valley typically has a U-shaped cross-section, with steep walls and a flat or gently sloping bottom. These valleys often have a wide floor and are characteristic of being carved out by the movement of glaciers.
What causes a glacial valley to be U-shaped Write your answer as a short detailed paragraph.?
A glacial valley becomes U-shaped through the process of glacial erosion. As a glacier moves down a valley, it erodes the land beneath it through a combination of abrasion and plucking. Abrasion occurs when the glacier grinds and sculpts the valley walls and floor, while plucking involves the glacier picking up and removing rock fragments. Over time, these erosional processes create a deep and wide valley with steep, straight sides characteristic of a U-shape.
Is a you shaped valley a slow change?
No, a U-shaped valley is typically formed by the slow movement of a glacier over a long period of time, eroding the valley floor and walls into a U shape. This process is a result of glacial erosion and can take thousands to millions of years to form.
The most prominent features of a narrow V-shaped valley where the stream profile drops rapidly are .?
The most prominent features of a narrow V-shaped valley with a rapidly dropping stream profile are steep valley walls, narrow width of the valley bottom, and a pronounced V shape that indicates erosion by the stream. These valleys often exhibit vertical erosion and can be associated with fast-flowing water and a high energy environment.
What is Difference between glaciar valley and river valley?
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.
Difference in shape of a typical stream carved valley compared to a typical glacial carved valley?
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.
What causes a glacial valley to be u shape?
When the glacier is moving down the side of the valley it scrapes of the rocks. The grinding changes the shape of the valley so that it is rounded.
What is the shape of a valley that is eroded by a stream and a glacier?
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
In high mountains a valley carved by a stream has the shape of a?
a "V"
What shape valley does a glacier leave?
Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
What is the best way to describe the shape of a glacial valley?
A glacial valley typically has a U-shaped cross-section, with steep walls and a flat or gently sloping bottom. These valleys often have a wide floor and are characteristic of being carved out by the movement of glaciers.
How must contour lines bend on a topographic map to indicate a stream valley?
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.
In high mountains a valley carved by a stream has the shape of what?
A valley carved by a stream in high mountains typically has a V-shaped profile, with steep sides and a narrow bottom. This shape is a result of the erosive power of the stream cutting down into the landscape over time, creating a deep, narrow channel.
What is a glacial trough and how does it form?
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.
What shape will a stream valley have if its primary work has been downward erosion cutting toward base level?
The stream valley will likely have a V-shaped profile characterized by steep sides and a narrow channel due to the primary work of downward erosion cutting towards base level. This shape results from the stream's ability to efficiently remove material through hydraulic action, abrasion, and corrosion. As the stream continues to erode downwards, the valley may deepen and widen over time.
Is U-shaped valley erosion or deposition?
U-shaped valley formation is a result of erosion, typically by glaciers. As the glacier moves downhill, it erodes the valley floor and sides, creating the distinct U-shape characteristic of glacial valleys.
