what are u shaped valleys [why not look here]?

A U-shaped valley is an edifice of geology that has high, steep sides and an elongated or flat valley bottom. These valleys are created by glaciation. They usually contain lakes or rivers, sandtraps along a golf courses, kettle lakes (water hazards), or other natural features.

Glacial erosion forms U-shaped valleys when the rocks are removed from the sides and the bottom of the valley. These valleys are common in mountainous regions all over the world.

Glaciers are responsible for the formation of them.

Glaciers are huge bodies of ice that are formed on mountains, and then move down them. As they degrade the landscape they create U-shaped valleys that have flat floors and steep sides. These valleys are distinct from the river valleys, which typically have the shape of a V. While glacial erosion can happen anywhere, these valleys tend to be more prevalent in mountainous areas. They are so distinct that it is easy to discern whether the landscape was formed by rivers or glaciers.

The process of creating a U shaped valley begins by creating a V shaped river valley. As the glacier degrades the landscape it encroaches on the V-shaped river valley and produces an inverted U shape. The ice also scrubbing the surface of land, causing high and straight walls on the sides of valley. This is known as glaciation and requires a lot of strength to move the earth in this way.

As the glacier continues to erode the landscape, it makes the valley wider and deeper. This is because the glacier has less frictional resistance than the surrounding rocks. As the glacier moves through the valley it also causes abrasion of the rock surfaces. This pulls the weaker rocks away from valley walls, a process known as plucking. These processes work together to smooth, widen and deepen the U-shaped valley.

These processes also cause a small side valley to be left hanging over the main valley. The valley could be filled with ribbon lakes that are formed when water flows through the glacier. The valley is also characterized by striations, ruts, and till on the sides as well as moraines and till on the floor.

The world is full of U-shaped valleys. Most commonly, they are found in mountainous areas like the Andes Mountains, Alps Mountains, Himalaya Mountains, Caucasus Mountains, and Rocky Mountains. In the United States they are usually found in national parks. Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana. In some cases the valleys can extend to coastal areas and become fjords. This is natural process that occurs when the glacier melts, and it could take hundreds of thousands of years for these valleys to be created.

They are deep

U-shaped valleys are distinguished by steep sides that curve at the bottom, and a wide, flat valley floor. They are created by river valleys which have been filled with glaciers during the Ice Age. Glaciers degrade valley floors through cutting and abrasion which causes the valley to widen and expand more evenly than it would with the flow of a river. These kinds of features are prevalent throughout the globe in mountainous areas which include the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

Glacial erosion of a valley in the river can transform it into a u-shaped one by expanding and deepening it. The erosive power of the glacier also causes smaller side valleys to be left hanging above the main valley, which is often characterized by waterfalls. These types of features are referred to as "hanging valleys" because they are suspended above the main valley, when the glacier retreats.

These valleys are typically surrounded by forests and may contain lakes. Some valleys can be used for agriculture while others are flood-prone. Many of these valleys are located in Alaska in the region where melting glaciers are the most evident.

Valley glaciers are huge streams of ice that resemble rivers and slowly move down the slopes of mountains during a glacier. They can be as deep as over 1000 feet and are the dominant form of valley erosion in alpine regions. They consume the rocks that lie at the bottom of the valley, leaving behind depressions and holes filled with water. The lakes that result are large and thin and they can be located in the peaks of a few mountains.

A glacial trough is yet another kind of valley. It is a U shape valley that extends out into the salt water to form a Fjord. They are prevalent in Norway, where they are referred to as fjords, but are also found in other parts of the world. They are created by melting ice and can be seen on maps around the globe. They are distinguished by their steep sides and round sides in a U-shape. The walls of the troughs are typically made of granite.

The slopes are steep

A U-shaped valley is a geological feature that has steep sides, high sides, and a flat base. Glaciers are the cause of many of these valleys. They are frequent in mountainous regions. This is because glaciers are slow-moving rivers of ice that move downhill, scouring the earth as they move. Scientists once thought that glaciers couldn't carve valleys due to being so soft. But now, we know they are able to.

Glaciers form distinctive u-shaped valleys through the processes of abrasion as well as plucking. These processes widen, increase the slope and deepen V-shaped river valleys to a U shape by eroding. They also change the slopes of the valley floor. These changes take place at the front of the glacier when it moves into the valley. This is the reason why the U shaped valley is often wider at the top and narrower at the bottom.

Sometimes, U-shaped valleys can be filled with lakes. These lakes are known as kettle lakes and they form in hollows that were eroded out of the rock by the glacier or dammed by moraine. The lake may be a temporary one when the glacier melts, or it could remain after the glacier has receded. They are often found in conjunction with cirques.

A flat-floored Valley is another type of valley. This is a valley formed by streams that degrade the soil, however it isn't the same steep slope as the U-shaped valley. They are generally located in mountainous areas and are often older than other types.

There are different types of valleys in the globe. Each one has its own distinct appearance. The most popular is a V-shaped valley but other types include U-shaped valleys as well as rift valleys. A rift valley develops in places where crust of the earth is separating. These are usually narrow valleys that have steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.

They are wide

Unlike V-shaped valleys, U-shaped valleys have broad bases. They are typically found in mountains and are formed by glaciers. Glaciers are huge blocks of snow and ice which erode the landscape as they slide downhill. They erode valleys through friction and erosion. This process is known as the scouring. As they degrade the landscape, the glaciers create distinct shapes that resemble an u shaped sleeper sectional-shaped letter. These valleys are referred to as U-shaped valleys and can be found in many locations around the globe.

The formation of these valleys takes place when glaciers erode existing river valleys. The glacier's slow motion and weight is able to erode the valley sides and floor, creating a distinctive U shape. This process, known as glacial erosive erosion, has resulted in some of the most stunning landscapes on Earth.

These valleys are often called glacial troughs or trough valleys. They are found all over the globe, and are especially found in areas that have glaciers and mountains. They can range in sizes ranging from a few meters to hundreds of kilometers. They also differ in depth and length. The deeper the valley, the greater the variation of temperature will be.

A ribbon lake or fjord is formed when a U-shaped valley is filled with water. The ribbon lakes develop in depressions where glaciers eroded less resistant rocks. They can also develop in valleys where the glacier was halted by a wall of moraine.

In addition to ribbon lakes, U-shaped valleys can also be filled with glacial features, such as hanging valleys, erratics, and moraine dams. Erratics, or huge boulders, are deposited by glaciers as it moves. The erratics are often used to define the boundaries of glaciated regions.

Hanging valleys are smaller side valleys left 'hanging' above the main valley formed by the glacier. These valleys are not as deep as the main valley and they contain less ice. They are formed by tributary glaciers and are often overshadowed by waterfalls.
