Five Killer Quora Answers To What Are U Shaped Valleys

what are u shaped valleys (read this post from Bookmarkspedia)?

A U-shaped valley is an ancient geological formation with steep, high sides and a flat or rounded valley bottom. These valleys are created by glaciation. They usually contain lakes rivers, sandtraps, sandtraps on golf courses kettle lakes (water hazards) or other natural features.

The process of glacial erosion creates U-shaped valleys when rocks are removed from the sides and bottom of the valley. These valleys can be seen in mountainous areas around the world.

Glaciers are responsible for forming them

Glaciers are massive bodies of ice which form on the tops of mountains and then slide down them. As they erode, they create u shaped sectional with sleeper shape valleys with flat floors and steep sides. These valleys are different from river valleys that are generally shaped like the letter V. While glacial erosion may be seen in a variety of places, these valleys are especially distinctive of mountain regions. They are so distinct that it is easy to discern whether the landscape was shaped by glaciers or rivers.

The formation of a U shaped valley begins by creating an V shape river valley. As the glacier degrades the landscape, it expands into the V-shaped river valley, and forms an inverted U-shaped. The ice also scratches the surface of the land, which causes the sides of the valley to have straight and high walls. This process is referred to as glaciation, and it takes the use of a lot of force to scour earth in this manner.

As the glacier continues to degrade the landscape, it also makes the valley bigger and deeper. This is due to the fact that glacier has a lower frictional resistance than the rocks around it. As the glacier moves through the valley it also causes friction on the rock surfaces and pulls the rocks that are weak away from the valley walls through a process called plucking. These processes are combined to widen, deepen and smooth the U-shaped valley.

This process can cause a small u shaped sofa valley to ‘hang’ above the main one. This valley is sometimes filled with ribbon lakes that are formed by the rushing of water through the glacier. The valley is also distinguished by striations and ruts on the sides and the floor, as well as till and moraines on the floor.

The world is filled with U-shaped valleys. Most commonly, they are found in mountainous areas 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 Glacier National Park and the Nant Ffrancon Valley in Wales. In some cases valleys can extend to the coast and turn into fjords. This is an natural process that occurs when the glacier melts and it can take many thousands of years to get these valleys formed.

They are deep

U-shaped valleys have steep sides that slop in at the base and broad flat valley floors. They are formed by rivers valleys which have been filled with glaciers during the Ice Age. Glaciers erode the valley floor through abrasion and plucking, which cause the valley to get deeper and broaden more evenly than a river would. These types of features are common throughout the globe in mountainous regions including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The erosion of a river valley can transform it into a u-shaped one by deepening and enlarging it. The force of erosion from the glacier can also create smaller side valleys, that are typically characterized by waterfalls, to float above the main valley. These types of features are referred to as “hanging valleys” because they hang over the main valley, as the glacier retreats.

These valleys may be covered in forest and may contain lakes. Some valleys are dry and used for farming, whereas others are flooded and may be visited as part of a kayaking or hiking excursion. Many of these valleys can be found in Alaska which is the region where melting glaciers is the 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 most prevalent type of alpine terrains that suffer from valley erosion. They consume the rocks that lie at the bottom of the valley, causing depressions and holes filled with water. The lakes that result are long and thin, and they are located in the peaks of certain mountains.

A glacial trough is yet another kind of valley. It is a U shape valley that extends into salt water to form a fjord. They can be found all over the globe including Norway and are referred to as fjords. They are created by melting the ice and can be found on maps around the globe. They are usually distinguished by rounded sides that mimic an U shape in cross-section as well as steep sides. The trough walls are generally carved out of granite.

They are sloping

A U form valley is a formation of geology with high, steep sides and a smooth bottom. They are common in mountainous regions and are usually formed by glaciers. This is due to glaciers being slow-moving rivers of ice which move downhill, scouring the earth as they move. Scientists once believed that glaciers wouldn’t be able to carve valleys because they were too soft. But now, we know they are able to.

Glaciers cut distinctive u-shaped valleys using the processes of plucking and abrasion. These processes broaden, steepen and deepen V-shaped valleys to a U shape through erosion. The valley’s slopes bottom are also altered. These changes occur at the front of a glacier when it traverses the valley. This is the reason why the top of a U-shaped valley is typically wider than the bottom.

Sometimes, U-shaped valleys may be filled with lakes. The kettle lakes are formed in hollows eroded by the glacier, or dammed by the moraine. The lake may be a temporary feature, as the glacier melts or it could remain after the glacier receding. They are usually located in conjunction with cirques.

Another type of valley is a flat-floored one. This valley is formed by streams which erode the soil. However, it does not have a steep slope as a U-shaped valley. They are typically found in mountainous areas and are often older than other kinds of valleys.

There are many different types of valleys in the world and each has a unique appearance. The most popular is a V-shaped valley however, other forms include u shaped sectional modern-shaped valleys as well as the rift valleys. A rift valley is one that develops in places where earth’s crust is splitting apart. These are often narrow valleys that have steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.

They are broad

U-shaped valleys are characterized by their wide bases, unlike V-shaped ones. Glaciers are the primary cause of these valleys, which are usually located in mountain ranges. Glaciers are massive blocks of snow and ice that erode the landscape as they slide downhill. They degrade valleys by friction and the abrasion. This erosion is known as Scouring. The glaciers degrade the landscape in a distinctive U-shaped pattern. These valleys, also known as U-shaped valleys, can be found in many locations across the globe.

The formation of these valleys takes place when glaciers degrade existing valleys of rivers. The weight of the glacier and its slow motion erodes the valley floor and sides and create a distinctive U-shaped shape. This process, also known as glacial erosion, has resulted in some of the most stunning landscapes on Earth.

These valleys are often referred to as glacial troughs or trough valleys. They are common throughout the globe, and are especially found in areas that have glaciers and mountains. They can vary in size from a couple of meters to hundreds of kilometers. They also differ in depth and length. The deeper the valley is the more intense the fluctuation of temperature will be.

If a U-shaped gorge is filled with water, it develops into a ribbon lake or fjord. The ribbon lakes develop in depressions where glaciers have eroded less resistant rocks. They can also form within valleys, where the glacier has been stopped by walls.

U-shaped valleys could also include other glacial features like moraine dams, hanging valleys and the erratics. Erratics, or huge boulders, are formed by glaciers as the latter moves. The erratics can be used to mark the boundaries between 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 contain less ice. They are created by tributary glaciers and are often capped by waterfalls.
