Which cross section best represents the valley shape where a rapidly flowing stream is cutting into the bedrock in mountains area?
A V-shaped cross-section would best represent the valley shape where a rapidly flowing stream is cutting into the bedrock in a mountainous area. The steep sides of the V-shape are characteristic of valleys formed by erosion from fast-flowing streams in mountainous terrain.
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.
How does a glacier-eroded valley differ from a stream-eroded valley?
A glacier-eroded valley will typically have a U-shape with steep sides and a flat bottom, while a stream-eroded valley usually has a V-shape with a narrow channel and wider floodplain. Glacier-eroded valleys are often much larger in scale and can be sculpted by the movement of thick ice over long periods of time, whereas stream-eroded valleys are shaped by the gradual erosion caused by flowing water.
What causes stream and valley erosion?
Stream erosion is mainly caused by the force of flowing water, which carries sediment and particles and can wear away the land it passes through. Valley erosion is a result of various factors, including the flow of water in streams and rivers, weathering of rocks, freeze-thaw cycles, and the movement of glaciers. Over time, these processes can shape and reshape the landscape of a valley.
Is a v- shaped valley formed by erosion or deposition?
A V-shaped valley is primarily formed by erosion, specifically by the action of a river or stream wearing away rock and sediment over time. The force of flowing water scours the landscape, carving out the valley shape. While some sediment may be deposited along the valley floor, the overall formation is due to erosion.
In high mountains a valley carved by a stream has the shape of a?
a "V"
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 is the shape of a valley left behind by a glacier?
The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
What are the rounded basins carved into the sides of mountains by valley glaciers?
Cirques are the rounded basins carved into the sides of mountains by valley glaciers. They are typically characterized by steep walls and a bowl-like shape. The process of glacial erosion forming cirques is known as plucking and abrasion.

A V-shaped cross-section would best represent the valley shape where a rapidly flowing stream is cutting into the bedrock in a mountainous area. The steep sides of the V-shape are characteristic of valleys formed by erosion from fast-flowing streams in mountainous terrain.
How does the shape of a stream valley compare to the shape of a glacial valley?
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 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.
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.
Is the Sacramento valley a you or v shaped valley?
The Sacramento Valley is primarily a flat, broad valley rather than being distinctly U-shaped or V-shaped. It was formed by the sedimentation from rivers and the surrounding Sierra Nevada mountains, resulting in a relatively gentle topography. While certain tributaries may have carved V-shaped valleys, the overall shape of the Sacramento Valley is more representative of a broad basin.
What is formed in the shape of long low land area between hills or mountains?
Valley
