A U-shaped valley is a geomorphological formation with high, steep sides and a rounded or flat valley bottom. They result from glaciation and are frequently filled with lakes, rivers and sand traps found on golf courses, kettle lakes (water hazards) and other natural features.
Glacial erosion creates U-shaped valleys as rocks are removed from the sides and the bottom of the valley. These valleys are found in mountainous regions around the globe.
Glaciers are responsible for forming them
Glaciers are large bodies of ice that are formed on mountains and then move down them. As they erode they create U shaped valleys that have flat floors and steep sides. These valleys differ from river valleys that are usually shaped in the shape of a V. While glacial erosion can happen everywhere, these valleys tend to be more common in mountainous regions. They are so distinct that you can tell whether the landscape was formed by glaciers or rivers.
The formation of a U-shaped valley starts with an existing V-shaped river valley. As the glacier erodes the landscape, it encroaches upon the V-shaped river valley and creates an inverted
u shaped sectional with sleeper-shaped shape. The ice also damages the surface of the ground, causing the sides of the valley to have straight and high walls. This process is known as glaciation and it requires a lot of strength to move the earth in this way.
As the glacier continues to degrade the landscape it also makes the valley more and more wide. This is due to the fact that ice has a lower frictional resistance than the surrounding 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 in a process called plucking. These processes are combined to widen, deepen and smooth the U-shaped valley.
These processes also cause a small side valley to hang above the main valley. This valley is sometimes filled with ribbon lakes which are formed by the rushing of water through the glacier. The valley is also marked with striations, ruts and till on the sides as well as moraines and till on the floor.
The world is full of U-shaped valleys. They are prevalent in mountainous areas, 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 these valleys extend to coastal areas and become Fjords. This is a natural process that occurs when the glacier melts. It can take thousands of years to build these valleys.
They are deep
U-shaped valleys have steep sides that curve towards the base, and broad flat valley floors. They are formed in valleys of rivers that were filled by glaciers during the ice age. The glaciers erode the valley's floor through abrasion and plucking, which cause the valley to grow deeper and broaden more evenly than a river would. These kinds of features can be seen in mountainous regions around the world including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.
The erosion of glaciers in the valley could transform it into a U-shaped valley by expanding and deepening it. The glacier's erosive force can also cause smaller side valleys which are usually characterized by waterfalls, to float above the main valley. These features are called "hanging valleys" because they are suspended above the main valley when the glacier recedes.
These valleys are usually located in forests and could contain lakes. Some valleys can be used for farming, while others are flooded. Many of these valleys are in Alaska in the region where glacial melting is most prominent.
Valley glaciers are massive river-like flows that slowly slide down mountain slopes. They can extend to depths of over 1000 feet, and are the predominant type of alpine terrains that suffer from valley erosion. They eat the rocks that lie at the bottom of the valley, leaving behind depressions and holes that are filled with water. The lakes that result are wide and thin, and can be located in the peaks of some mountains.
A glacial trough is a different type of valley. It is an U shaped valley that extends into salt water to create an Fjord. These are typical in Norway and are known as fjords. However, they are also found in other areas of the world. They are formed by melting glaciers, and can be seen on maps of the world. They are characterized by their steep sides and rounded sides that form an U-shape. The walls of troughs are typically constructed from granite.
The slopes are steep
A U shaped valley is a type of formation with steep, high sides and a rounded bottom. They are quite frequent in mountainous regions and are usually formed by glaciers. This is due to glaciers being slow moving rivers of ice which move downhill, scouring land as they move. Scientists used to believe that glaciers couldn't create a valley because they are so soft, but now we know that they do create these forms.
Glaciers form distinctive u-shaped valleys using the processes of plucking as well as abrasion. These processes broaden, steepen and deepen V-shaped river valleys to the U shape through erosion. The valley's slopes bottom are also altered. These changes take place at the front of the glacier when it turns into a valley. This is the reason why a U form valley is typically wider at the top than at the bottom.
Sometimes, U-shaped valleys may be filled with lakes. The kettle lakes are formed in hollows that have been eroded by the glacier, or blocked by the moraine. The lake could be a temporary feature when the glacier melts or remains even after the glacier has receded. These lakes are often located alongside cirques.
A flat-floored Valley is a different kind of valley. It is a type of valley created by streams that degrade the soil, however it doesn't have the same slope as a U-shaped valley. They are typically found in mountainous regions and are often older than other types.
There are many types of valleys around the globe. Each one has its own distinctive appearance. The most popular type of valley is the V-shaped one, but there are also rift and U-shaped valleys. A rift valley is formed in areas where the crust of the earth is breaking apart. They are usually narrow valleys that have steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.
They are wide
In contrast to V-shaped valleys U-shaped valleys have broad bases. They are usually found in mountain ranges and are shaped by glaciers. Glaciers are massive blocks of snow and ice which erode the landscape as they slide downhill. They degrade valleys by friction and erosion. This is referred to as the scouring. As they degrade the landscape, glaciers create an unusual shape that resembles a letter U. These valleys, also referred to as U-shaped Valleys, are able to be found in a variety of locations across the globe.
The formation of these valleys occurs when glaciers erode existing valleys of rivers. The weight of the glacier and its slow movement erode the valley floor and sides creating a unique U-shaped shape. This process, referred to 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, and are especially found in regions that have glaciers and mountains. They can vary in size from a couple of meters to hundreds of kilometers. They also can vary in depth and length. The fluctuations in temperature will be greater the deeper the valley.
