what are u shaped settee shaped valleys (http://legendawiw.ru/forum/index.php?action=profile;u=182994)?

A U-shaped valley is a geomorphological formation with high, steep sides and a rounded or flat valley bottom. These valleys are formed by glaciation. They often contain lakes, rivers, sandtraps on golf course kettle lakes (water hazards), or other natural features.

The erosion of glaciers creates U-shaped valleys, caused by the plucking of rocks from the bottom and side of the valley. These valleys can be seen in mountainous areas around the globe.

They are formed by glaciers.

Glaciers are massive bodies of ice which form 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 river valleys which are usually shaped in the shape of an X. While glacial erosion can happen anywhere but these valleys tend to be more prevalent in mountainous areas. In fact, they are so distinct that you can determine if the landscape was created by glaciers or rivers.

The formation of a U shape valley begins by creating the V shape river valley. As the glacier degrades the landscape, it expands into the V-shaped river valley, and forms an inverted U-shaped shape. The ice also scrubbing the land's surface, causing high and straight walls along the sides of the valley. This process is referred to as glaciation and it requires an enormous amount of strength to scour earth this way.

As the glacier continues to degrade the landscape, it also makes the valley bigger and deeper. The ice is less frictional than the rocks. As the glacier moves through the valley it also causes abrasion of the surfaces of the rocks. This pulls weaker rocks away from the valley walls through a process called plucking. These processes combine to increase the width, depth and smooth the U-shaped valley.

This also causes a small valley to 'hang above the main one. The valley may be filled with ribbon lakes that are created when water flows through the glacier. The valley is also distinguished with striations, ruts and till on the sides, as well as moraines and till on the floor.

The world is filled with u shaped leather sofas-shaped valleys. They are typically located in mountainous regions 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 these valleys extend to coastal locations and then become fjords. This is a natural process that occurs when the glacier melts. It could take thousands of years to form these valleys.

The ocean's depths are deep

U-shaped valleys are distinguished by steep sides that curve towards the bottom and a wide flat valley floor. They are formed by river valleys which have been filled with glaciers during the Ice Age. Glaciers erode valley floors by cutting and abrasion which causes the valley to expand and expand more evenly than with a river. These features are found around the globe in mountainous areas including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The glacial erosion of a valley may transform it into a U-shaped valley by expanding and deepening it. The force of erosion from the glacier can also cause smaller side valleys which are usually characterized by waterfalls, to rise above the main valley. These types of valleys are known as "hanging valleys" because they are suspended above the main valley when the glacier retreats.

These valleys are typically covered by forests, and can contain lakes. Some valleys are dry and used for farming, while others are flooded and can be visited as part of a hiking or kayaking excursion. Many of these valleys are in Alaska, the place where glacial melting is most prominent.

Valley glaciers are huge flowing ice like rivers that slowly move down mountain slopes during a glaciation. They can extend to depths of over 1000 feet and are the predominant form in the alpine regions of valley erosion. They eat away the rocks that lie at the bottom of the valley, leaving behind depressions and holes filled with water. The lakes that result are narrow and long and are found on the tops of certain mountains.

Another kind of valley, a glacial trough is a U-shaped valley which extends into saltwater and forms the Fjord. They can be found everywhere in the world including Norway and are referred to as Fjords. They are created by melting glaciers, and can be seen on a map of the world. They are characterized by their steep sides and rounded sides that form the U-shape. The walls of the troughs are typically made of granite.

They are steep

A u shaped sectional chaise shaped valley is a type of formation with steep, high sides and a rounded bottom. Glaciers are responsible for many of these valleys. They are prevalent in mountainous regions. It is because glaciers move slowly downhill and scour the land. Scientists used to believe that glaciers couldn't create valleys because they were so soft, but now we know that they can create these forms.

Glaciers form distinctive u-shaped valleys by using the processes of plucking and abrasion. These processes broaden, steepen and deepen V-shaped valleys to the U shape through erosion. They also change the slopes of the valley floor. These changes happen at the front of the glacier when it turns into a valley. This is the reason why the top of a sectional u shaped couch-shaped valley is typically wider than the bottom.

Sometimes, U-shaped valleys can be filled with lakes. These kettle lakes form in hollows eroded by the glacier or surrounded by the moraine. The lake may be a temporary feature as the glacier melts or it may remain even after the glacier has receded. These lakes are usually found along with cirques.

A flat-floored Valley is another type of valley. It is a type of valley created by streams that break up the soil, however it doesn't have as steep of a slope as the U-shaped valley. They are usually located in mountainous areas and can be much older than other types.

There are many different types of valleys across the globe, and each has a distinct appearance. The most common kind of valley is the V-shaped one, but there are also rift and U-shaped valleys. A rift valley forms where the earth's surface splits apart. These are usually narrow valleys with steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.

They are wide

U-shaped valleys are characterized by their broad bases, unlike V-shaped ones. Glaciers are the primary cause of these valleys, which are typically found in mountain ranges. Glaciers are massive blocks of snow and ice that erode the landscape as they move downhill. They degrade valleys by friction and erosion. This erosion is known as Scouring. As they degrade the landscape, the glaciers create distinct shapes that resemble the letter U. These valleys, also known as U-shaped Valleys, are able to be found in numerous places around the world.

The valleys are formed when glaciers erode the valleys of rivers. The glacier's slow motion and weight degrades the valley sides and floor creating a distinct U shape. This process is referred to as glacial erosion, and has led to some of the most beautiful landscapes on Earth.

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

A fjord or ribbon lake is formed when a U-shaped valley is filled with water. The ribbon lakes are formed in depressions where glaciers eroded less resistant rock. They can also form within a valley, in which the glacier is stopped by the wall.

U-shaped valleys can also contain other glacial features like moraine dams, hanging valleys, and erratics. Erratics are massive rocks that were left behind by glaciers during their movement. The erratics are often used to define the boundaries of glaciated regions.

Hanging valleys are smaller side valleys that are left 'hanging' above the main valley that was created by the glacier. They aren't as deep as the main valley, and they are ice-free. They are formed by tributary glaciers, and are usually covered by waterfalls.
