what are u shaped valleys (more information)?

A U-shaped valley is a geomorphological formation that has steep, high sides and a flat or rounded valley bottom. They result from glaciation, and are usually filled with lakes, rivers, sand traps on golf courses, kettle lakes (water hazards), and other such natural features.

Glacial erosion causes u shaped sectional double chaise-shaped valleys, caused by the plucking of rocks from the bottom and side of the valley. These valleys are found in mountainous regions across the globe.

They are created by glaciers.

Glaciers are huge u shaped sectional bodies of ice that are formed on mountains and then move down them. As they erode the landscape they create U-shaped valleys with flat floors and steep sides. These valleys differ from the river valleys, which typically have the shape of an X. While glacial erosion can happen anyplace but these valleys tend to be more common in mountainous regions. They are so distinctive that you can tell whether the landscape has been shaped by glaciers or by rivers.

The formation of a U shaped valley begins by forming an V formed river valley. As the glacier melts and encroaches on the V-shaped valley of the river and creates an inverted U-shape. The ice also scratches the surface of the land, causing high and straight walls along the sides of the valley. This process is referred to as glaciation and requires an enormous amount of strength to scour the earth this way.

As the glacier continues to erode the landscape, it makes the valley larger and deeper. This is because the glacier has a lower frictional resistance compared to the rocks around it. As the glacier moves through the valley it also causes abrasion to the surfaces of the rocks. This pulls the weaker rocks away from the valley walls, a process known as plucking. These processes combine to increase the width, depth and smooth the U-shaped valley.

This can cause a small u shaped sectional valley to 'hang' above the main one. This valley is often filled with ribbon lakes, that are formed by the flow of water that flows through the glacier. The valley is also distinguished by striations, ruts and striations on the sides and the floor, as also moraines and till on the floor.

The world is full of U-shaped valleys. They are prevalent in mountainous regions, including the Andes, Alps, Caucasus, Himalaya and Rocky Mountains. In the United States, they are usually found in national parks. Examples include Glacier National Park and the Nant Ffrancon Valley in Wales. 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 can take hundreds of thousands of years for these valleys to be formed.

They are deep

U-shaped valleys have steep sides that curve into the bottom and broad, flat valley floors. They are created by river valleys that have been filled with glaciers during the Ice Age. Glaciers degrade the valley floor through abrasion and plucking and cause the valley to deepen and widen more equally than a river would. These types of features are found in mountainous regions all over the globe including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The erosion of glaciers in a valley can change it into a U-shaped valley by enlarging and deepening it. The erosive force of the glacier also causes smaller side valleys to be left hanging above the main valley which is often characterized by waterfalls. These are referred to as "hanging valleys", because they are hung over the main valley, when the glacier retreats.

These valleys could be enclosed by forests and contain lakes. Some valleys can be used for agriculture while others are flood-prone. A majority of these valleys are in Alaska which is where glacial melt is at its most intense.

Valley glaciers are massive streams of ice that resemble rivers and slowly move down mountain slopes during a glaciation. They can be as deep as over 1000 feet, and are the most prevalent form of valley erosion in regions of alpine. They consume the rocks that lie at the bottom of the valley, causing depressions and holes filled with water. The lakes that result are large and thin and they can be found in the peaks of certain mountains.

Another type of valley, called a glacial trough, is a U-shaped valley that extends into salt water and forms a Fjord. These are common in Norway in Norway, where they are known as fjords. However, they are also found in other areas of the world. They are created by melting glaciers, and can be seen on maps of the world. They are characterized by steep sides and rounded sides with an U-shape. The trough walls are usually carved out of granite.

They are sloping

A u shaped sofa with ottoman-shaped valley is a geomorphological feature that has steep sides, high sides and a flat base. They are very frequent in mountainous regions and are usually formed by glaciers. This is because glaciers move slowly downhill and then scour the land. Scientists used to believe that glaciers could not carve a valley because they were so soft, but now we know they do create these forms.

Glaciers form distinctive U-shaped valleys as a result of the processes of abrasion as well as plucking. Through erosion these processes may widen, steepen, and deepen V shape river valleys. The valley's slopes bottom are also altered. These changes take place at the top of a glacier as it traverses a valley. This is why the top of a U-shaped valley is usually wider than the bottom.

U-shaped valleys can be filled with lakes. These lakes are known as kettle lakes. They are formed in hollows that were created out of the rock by the glacier or drained by the moraine. The lake may be a temporary feature, when the glacier melts, or it may remain even after the glacier has receded. They are often associated with cirques.

Another type of valley is a flat-floored valley. This is a valley formed by streams that degrade the soil, however it isn't the same slope as an U-shaped valley. They are generally located in mountainous areas and are more affluent than other types.

There are many different types of valleys around the world and each has a unique appearance. The most well-known is a V-shaped valley, but other types include U-shaped valleys and rift valleys. A rift valley forms in places where the earth's crust is splitting apart. They are usually narrow valleys with steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good illustration of this.

They are wide

In contrast to V-shaped valleys U-shaped valleys have broad bases. Glaciers are responsible for creating these valleys, which are typically found in mountain ranges. Glaciers are huge blocks of snow and ice that degrade the landscape as they slide downhill. They erode valleys through friction and abrasion. This erosion is called Scouring. The glaciers break up the landscape in a distinctive U-shaped pattern. These valleys, often referred to as U-shaped Valleys, can be found in a variety of places around the world.

The formation of these valleys happens when glaciers degrade existing river valleys. The weight of the glacier and its slow movement erode the valley's sides and floor and create a distinctive U-shaped shape. This process, known as glacial erosive erosion has resulted in some of the most stunning landscapes on Earth.

These valleys can also be called trough valleys or glacial troughs. They are common throughout the globe, but are particularly found in regions with glaciers and mountains. They can vary in dimensions from a few meters to several hundred kilometers. They can also vary in length and depth. The fluctuations in temperature will be higher the deeper the valley.

A fjord or ribbon lake is formed when a U-shaped valley is filled with water. The ribbon lakes form in the depressions in which the glacier cut the rock that was less resistant. They also can develop in valleys in which the glacier was stopped by a moraine wall.

In addition to U-shaped valleys, the ribbon lakes can also contain glacial features, such as hanging valleys, erratics, and moraine dams. Erratics are massive rocks that were deposited by glaciers during their movement. The erratics can be used to define the boundaries between glaciated areas.

These smaller valleys are left 'hanging" above the main valley that was created by the glacier. They aren't as deep as the main valley and they have less ice. They are formed by glaciers that tributary to the main valley and are often overshadowed by waterfalls.
