what are u shaped valleys, Read the Full Document,?

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

The process of erosion caused by glacial erosion creates U-shaped valleys, caused by the plucking of rocks from the bottom and side of the valley. These valleys can be found in mountainous regions all over the globe.

They are created by glaciers.

Glaciers are massive masses of ice that form and move down mountains. When they degrade the landscape, they create U-shaped valleys with flat floors and steep sides. These valleys are different from river valleys that are typically shaped like the letter V. Although glacial erosion can occur in many places but these valleys are characteristic of mountain areas. They are so distinct that you can tell if the landscape was created by glaciers or by rivers.

The formation of a U-shaped gorge begins with an existing V-shaped river valley. As the glacier erodes the landscape it encroaches on the V-shaped river valley and creates an inverted U-shaped. The ice also scoures the surface of the land, causing the valley's sides to have high and straight walls. This process is known as glaciation and it requires the use of a lot of force to break up the earth this way.

As the glacier continues to degrade the landscape, it makes the valley deeper and wider. The glacier's ice is less frictional than the rocks. As the glacier moves through the valley it also causes abrasion to the surfaces of the rocks. This pulls weaker rocks away from valley walls, a process known as plucking. These processes are used together to broaden, smoothen and deepen the U-shaped valley.

This also causes a small u shape sofa valley to 'hang' above the main one. The valley may be filled with ribbon lakes formed when water rushes 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.

U-shaped valleys are commonplace everywhere in the world. Most commonly, they are found in mountainous regions like the Andes Mountains, Alps Mountains, Himalaya Mountains, Caucasus Mountains, and Rocky Mountains. In the United States, they are typically found in national parks. Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana. In some instances, valleys can extend to the ocean and transform into fjords. This is a natural phenomenon that occurs when the glacier melts. It could take thousands of years to form these valleys.

The depths of the ocean are deep

U-shaped valleys have steep sides that curve towards the base, and large flat valley floors. They are formed by river valleys which have been filled with glaciers during the Ice Age. Glaciers degrade the valley floor by plucking and abrasion, which cause the valley to get deeper and broaden more evenly than a river would. These features are found around the globe in mountainous regions, including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The erosion of glaciers in the valley could transform it into a U-shaped valley by enlarging and deepening it. The erosive power of the glacier also causes smaller side valleys to hang above the main valley, which is often identified by waterfalls. These are referred to as "hanging valleys" because they are suspended above the main valley when the glacier recedes.

These valleys are often covered in forest and may contain lakes. Some valleys can be used for agriculture while others are flood-prone. Many of these valleys can be found in Alaska, the place where melting glaciers is the most evident.

Valley glaciers are huge flowing ice like rivers that slowly creep down mountain slopes during a glaciation. They can extend to depths of 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 narrow and long and can be found on the peaks of certain mountains.

A glacial trough is yet another kind of valley. It is a U shaped valley that extends into salt water to create the fjord. They can be found all over the world and include Norway and are referred to as Fjords. They are created by melting the ice and can be found on maps of the world. They are typically characterized by their rounded sides, which resemble an U shape in cross-section as well as steep sides. The trough walls are usually constructed from granite.

The slopes are steep.

A U shape valley is a geological formation with steep, high sides and a rounded bottom. They are very frequent in mountainous areas and are usually formed by glaciers. This is because glaciers are slow-moving rivers of ice which move downhill, scouring the land as they move. Scientists used to believe that glaciers could not create valleys because they were too soft. However, now we know that they are able to.

Glaciers form distinctive u-shaped valleys through the processes of abrasion and plucking. These processes widen, increase the slope and deepen V-shaped river valleys to a U shape by eroding. The slopes of the valley bottom are also altered. These changes occur in the front of the glacier as it is pushed into the valley. This is why the top of a U-shaped valley is usually larger than the lower.

Sometimes, u shaped sectional coffee table-shaped valleys can be filled with lakes. These lakes are called kettle lakes and they form in hollows that were eroded out of the rock by the glacier or dammed by moraine. The lake could be a temporary feature as the glacier melts or remains after the glacier recedes. These lakes are usually located alongside cirques.

Another kind of valley is a flat-floored valley. This is a valley formed by streams that erode the soil, however it doesn't have as steep of a slope as the U-shaped valley. They are often located in mountainous areas and can be a lot older than other kinds of valleys.

There are many types of valleys in the world. Each one has its own unique appearance. The most well-known kind of valley is a V-shaped, but there are also U-shaped and rift valleys. A rift valley is formed in areas where the earth's crust is splitting apart. These are typically narrow valleys with steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good example of this.

They are broad

U-shaped valleys are characterized by their broad bases, unlike V-shaped ones. They are most often found in mountains and are formed by glaciers. Glaciers are massive blocks of snow and ice which erode the landscape as they slide downhill. They erode valleys through friction and abrasion. This is referred to as scouring. When they begin to erode the landscape, the glaciers create distinct shapes that resemble an sofa bed u shape-shaped letter. These valleys, also known as U-shaped valleys, can be found in many locations around the globe.

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

These valleys can also be called trough valleys or glacial troughs. They are found all over the globe, but are particularly found in regions with 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, the greater the variation of temperature will be.

If a U-shaped gorge is filled with water, it develops into a ribbon lake or fjord. The ribbon lakes form in depressions where glaciers have eroded less resistant rock. They also can be formed in valleys where the glacier was stopped by a wall of moraine.

In addition to U-shaped valleys, the ribbon lakes may also have glacial features such as hanging valleys, erratics, and moraine dams. Erratics are massive rocks that were deposited by glaciers during their movement. They are commonly used to mark the boundaries of glaciated regions.

Hanging valleys are smaller side valleys hanging above the main valley that was created by the glacier. These valleys are not as deep as the main valley and they are ice-free. These valleys are created by tributary ice, and are usually covered by waterfalls.
