Smaller glacial valleys that join a deeper main valley are often referred to as tributary valleys or hanging valleys. These valleys typically form when smaller glaciers flow into a larger glacier, resulting in a steep drop-off where the tributary meets the main valley. As the main glacier erodes the landscape, it carves out a deeper trough, leaving the smaller valleys elevated, which can create stunning waterfalls when the tributary streams plunge into the main valley below. This geological feature is common in mountainous regions shaped by glacial activity.

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 kind of terrain and landforms would indicate the prior existence a valley glacier?
The presence of U-shaped valleys, which are often wider and deeper than river valleys, indicates the former existence of a valley glacier. Other landforms such as moraines, which are accumulations of debris deposited by the glacier, and cirques, which are bowl-shaped depressions at the glacier's head, also suggest glacial activity. Additionally, features like fjords or hanging valleys can provide evidence of glacial erosion. Scratched and polished bedrock surfaces, known as glacial striations, further indicate the movement of a glacier across the terrain.
Is a valley formed from water or wind or ice?
Valleys can be formed by various factors, including water erosion, glacial activity, and wind erosion. Water eroded valleys are typically created by rivers or streams, while glacial valleys are carved out by moving glaciers. Wind can also contribute to valley formation through processes like deflation or abrasion.
What are the erosional features you might expect to see in an area where valley glaciers exist or have existed?
Erosional features in areas with valley glaciers include U-shaped valleys, cirques (bowl-shaped hollows at the head of glaciers), arêtes (sharp ridge between cirques), and hanging valleys (smaller valleys that join a main glacier valley). Glacial striations (scratches on bedrock caused by moving glacier ice) and moraines (piles of debris deposited by glaciers) are also common erosional features.
What is the differences between v-valley and u-valley?
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.
What are smaller glacial valleys that join the deeper main valley?
They are called hanging valleys. The smaller glacier valleys are the hanging walls that join the deeper main valley called the U-shaped valley.
Glacial valleys shaped differently from river valleys?
u shaped valley..
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.
Which valley are 'U' shaped valley?
A U-Shaped Valley is formed by glacial erosion.
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.
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 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.
What kind of terrain and landforms would indicate the prior existence a valley glacier?
The presence of U-shaped valleys, which are often wider and deeper than river valleys, indicates the former existence of a valley glacier. Other landforms such as moraines, which are accumulations of debris deposited by the glacier, and cirques, which are bowl-shaped depressions at the glacier's head, also suggest glacial activity. Additionally, features like fjords or hanging valleys can provide evidence of glacial erosion. Scratched and polished bedrock surfaces, known as glacial striations, further indicate the movement of a glacier across the terrain.
How are hanging vallies formed?
Hanging valleys are formed when smaller glaciers flowing from tributary valleys join a larger glacier in a main valley. As the larger glacier is more powerful, it erodes the main valley deeper than the tributary valleys. This results in the tributary valleys being left at higher elevations once the glaciers retreat, creating the characteristic "hanging" appearance.
Is a valley formed from water or wind or ice?
Valleys can be formed by various factors, including water erosion, glacial activity, and wind erosion. Water eroded valleys are typically created by rivers or streams, while glacial valleys are carved out by moving glaciers. Wind can also contribute to valley formation through processes like deflation or abrasion.
How do glacial valleys form?
Glacial valleys form through the process of glacial erosion, where the movement of a glacier carves and shapes the valley over time. As the glacier moves downhill, it picks up rocks and sediments, which act as abrasives that wear away the underlying rock. The downward pressure and friction of the glacier further deepen and widen the valley, creating a distinct U-shaped profile.
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.
