5 Killer Quora Answers On What Are U Shaped Valleys

What Are U Shaped Valleys?

A U-shaped Valley is an ancient geological formation with steep, high sides as well as flat or rounded valley bottom. They result from glaciation, and are usually home to lakes, rivers and sand traps found on golf courses kettle lakes (water hazards) and other natural features.

The erosion of glaciers creates U-shaped valleys by plucking rocks from the bottom and side of the valley. These valleys are found in mountainous regions around the world.

They are created by glaciers.

Glaciers are massive bodies of ice which form on the tops of mountains and then slide down them. When they degrade the landscape, they create U-shaped valleys that have flat floors and steep sides. These valleys are different from the valleys of rivers, which are usually shaped like the letter V. While glacial erosion may occur in many places however, these valleys are distinctive of mountain regions. They are so distinct that it is easy to discern whether the landscape was created by rivers or glaciers.

The formation of a U-shaped gorge begins with an existing V-shaped river valley. As the glacier erodes it, it expands into the V-shaped valley of the river, and forms a U-shaped inverted shape. The ice also scrubbing the surface of land creating straight and high walls along the sides of the valley. This process is referred to as glaciation and requires an enormous amount of strength to break up the earth in this manner.

As the glacier continues to degrade the landscape, it makes the valley bigger and deeper. This is due to the fact that ice has a lower frictional resistance compared to the rocks around it. As the glacier moves through the valley it also causes abrasion on the rock surfaces and pulls the weakend rocks away from the valley walls in a process known as plucking. These processes work together to widen, deepen and smooth the U-shaped valley.

This also causes the small valley to "hang' above the main one. This valley is often filled with ribbon lakes which are formed by the rushing of water through the glacier. The valley is also characterized with striations and ruts, till on the sides as well as moraines and till on the floor.

The world is filled with u shaped sectional grey-shaped valleys. They are typically found in mountainous areas, such as 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 instances the valleys can extend to coastal areas and become fjords. This is a natural process that happens when the glacier melts, and it could take many thousands of years for these valleys to be formed.

They are deep

U-shaped valleys are characterized by steep sides that curve towards the bottom and wide, flat valley floor. They are formed by valleys of rivers that were filled by glaciers during the Ice Age. Glaciers erode valley floors by cutting and abrasion, which makes the valley widen and expand more evenly than it would with the flow of a river. These features can be found in mountainous regions all over the globe, including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The glacial erosion of the valley could transform it into a U-shaped valley, by enlarging and deepening it. The erosive force of the glacier can cause smaller side valleys to be left hanging above the main valley which is usually marked by waterfalls. These are referred to as "hanging valleys" due to the fact that they hang over the main valley, when the glacier retreats.

These valleys could be enclosed by forests and contain lakes. Some valleys are used for farming, while others are filled with water. A majority of these valleys are in Alaska which is where glacial melt is at its most intense.

Valley glaciers are huge streams of ice that resemble rivers and slowly slide down the slopes of mountains during a glaciation. They can be as deep as 1000 feet, and are the most prevalent form in alpine areas of valley erosion. They devour the rocks on the bottom of a valley, leaving behind depressions or holes that are then filled with water. The resulting lakes are large and thin and they are found in the peaks of some mountains.

Another kind of valley, called a glacial trough is a U-shaped valley that extends into saltwater and forms the Fjord. They can be found all over the globe, including Norway, where they're called Fjords. They are created by melting glaciers and are visible on a map of the globe. They are characterized by steep sides and rounded sides with an U-shape. The walls of the troughs are usually made from granite.

The slopes are steep

A U-shaped valley is an important geological feature that has steep sides, high sides and a rounded base. Glaciers are the reason for many of these valleys. They are common in mountainous areas. This is because glaciers are slow-moving rivers of ice that move downhill, scouring the earth as they go. Scientists used to believe that glaciers couldn't carve valleys because they were so soft. However, now we know that they are able to.

Glaciers cut distinctive u-shaped valleys by using the techniques of plucking and abrasion. Through erosion these processes may broaden, steepen, and deepen V formed river valleys. They also alter the slopes of the valley floor. These changes take place at the front of a glacier when it moves through a valley. This is why the U shaped valley is often wider at the top and narrower at the bottom.

U shaped valleys are sometimes filled with lakes. These lakes are known as kettle lakes. They are formed in hollows which were eroded 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 after the glacier has receded. They are often associated with cirques.

Another kind of valley is a flat-floored one. 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 typically found in mountainous areas and can be a lot older than other types of valleys.

There are many different types of valleys across the globe and each has a unique appearance. The most popular is a V-shaped valley, but there are other varieties, including U-shaped valleys and rift valleys. A rift valley forms where the earth's surface is splitting into two. They are usually narrow valleys that have steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good example of this.

They are broad

U-shaped valleys are distinguished by their broad bases unlike V-shaped ones. Glaciers are the primary cause of these valleys, which are generally found in mountain ranges. Glaciers are massive blocks of snow and ice which erode the landscape as they slide downhill. They degrade valleys by crushing the rocks with friction and abrasion. This erosion is called the scouring. As they erode the landscape, the glaciers form an unusual shape that resembles an U-shaped letter. These valleys, also known as U-shaped Valleys, can be found in a variety of locations around the globe.

These valleys are formed by glaciers that erode valleys of rivers. The glacier's slow motion and weight erodes the valley's floor and sides and creates a distinctive U shape. This process is known as glacial erosion and has resulted in some of the most breathtaking landscapes on Earth.

These valleys are often called trough valleys or glacial troughs. These valleys are found throughout the world, but especially in areas with mountains and glaciers. They range in dimensions from a few meters to hundreds of kilometers. They can also vary in depth and length. The fluctuations in temperature will be greater the deeper the valley.

If a U-shaped gorge is filled with water, it creates a ribbon lake or fjord. The ribbon lakes are formed in the depressions in which the glacier cut the rock with less resistance. They can also develop in valleys in which the glacier was stopped by a wall of moraine.

U-shaped valleys can also contain other glacial features, such as hanging valleys, moraine dams and Erratics. Erratics are massive boulders that were dumped by the glacier during its movement. The erratics can be used to define the boundaries between glaciated regions.

These smaller valleys hang" above the main valley that was created by the glacier. They aren't as deep than the main valley and they contain less ice. They are created by tributary glaciers and are usually covered by waterfalls.
