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 shapes are the valleys made by fast flowing rivers or glaciers?
Valleys made by fast-flowing rivers tend to have V-shapes, while valleys formed by glaciers typically have U-shapes. The V-shape of river valleys is due to the erosive forces of the water cutting down into the landscape over time. Glaciers carve out U-shaped valleys as their massive weight and movement scrape away at the rock below.
Do glaciers fill valleys?
It does!
How do water gaps and canyons and valleys form?
Water gaps are formed when rivers erode through a mountain range, creating a gap or pass. Canyons are typically formed by the erosion of rivers or glaciers cutting through rock layers over time. Valleys can be formed by various geological processes, including erosion by rivers, glaciers, or tectonic activity.
What landforms are created by glaciers and how?
Glaciers create various landforms such as U-shaped valleys, moraines, drumlins, and fjords through processes like erosion, deposition, and melting. For example, as glaciers move, they erode the land beneath them, forming U-shaped valleys. When glaciers retreat, they leave behind piles of debris called moraines. Drumlins are elongated hills formed by glaciers depositing sediments, and fjords are deep, narrow inlets created by glaciers moving through valleys and subsequently melting.
What are glaciers formed in mountains called?
Glaciers formed in mountains are called mountain glaciers or alpine glaciers. They are found in high-altitude regions and flow downhill through valleys.
What is one land feature formed by glaciers?

What kinds of valleys are there?
There are several types of valleys, including V-shaped valleys formed by erosion from rivers, U-shaped valleys carved by glaciers, rift valleys formed by tectonic activity, and hanging valleys created when smaller tributary valleys flow into larger main valleys.
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.
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.
Alpine glaciers can be found on which landform?
Alpine glaciers are found in mountain valleys
Was Yosemite valley formed by wind?
No. Wind can cause some erosion, but it cannot form valleys. Yosemite valley was formed by glaciers.
What is a description of armchair shaped valleys?
Armchair-shaped valleys are U-shaped valleys that have a distinctive shape resembling an armchair. They are formed by glaciers eroding the landscape, creating steep side walls and a broad, flat bottom. These valleys are often found in mountainous regions where glaciers once existed.
Are U-shaped valleys destructive or constructive?
U-shaped valleys are considered destructive landforms because they are formed by the erosive action of glaciers. Glaciers carve out these valleys by plucking and abrasion, which erode the surrounding rock and soil. The resulting U-shaped valleys often leave behind steep, rocky walls and a flat valley floor, reshaping the landscape in the process.
What land features are formed from ice erosion?
Land features formed from ice erosion include cirques, u-shaped valleys, and fjords. Cirques are bowl-shaped depressions at the head of a glacier, u-shaped valleys are deep valleys with steep sides carved out by glaciers, and fjords are long, narrow inlets with steep cliffs created by glaciers flowing into the sea.
What shapes are the valleys made by fast flowing rivers or glaciers?
Valleys made by fast-flowing rivers tend to have V-shapes, while valleys formed by glaciers typically have U-shapes. The V-shape of river valleys is due to the erosive forces of the water cutting down into the landscape over time. Glaciers carve out U-shaped valleys as their massive weight and movement scrape away at the rock below.
Water passes through what cliffs formed by glaciers?
Water can pass through U-shaped valleys formed by glaciers. These valleys have steep, straight sides that are often polished or have sheer rock faces known as cliffs. This creates an ideal pathway for water to flow or be contained within the valley.
