Five Killer Quora Answers To What Are U Shaped Valleys
what are u shaped valleys [this hyperlink]?
A U-shaped valley is an edifice of geology that has steep, high sides as well as an elongated or flat valley bottom. These valleys are created by glaciation. They are often filled with lakes rivers, sandtraps, sandtraps on golf courses kettle lakes (water hazards) or other natural features.
The erosion of glaciers creates U-shaped valleys by plucking rocks from the bottom and side of the valley. These valleys can be seen in mountainous areas around the world.
They are formed by glaciers
Glaciers are huge bodies of ice that 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 are distinct from the valleys of rivers that are typically designed to look like the letter V. While glacial erosion can occur in many locations, these valleys are especially typical of mountain regions. They are so distinct that you can determine if the landscape was created by glaciers or rivers.
The formation of a U-shaped valley begins with an existing V-shaped river valley. As the glacier is eroding the landscape, it encroaches upon the V-shaped river valley and produces an inverted U-shaped shape. 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 known as glaciation and requires a great deal of strength to scour the earth this manner.
As the glacier continues to erode the landscape, it also makes the valley more and more wide. The ice is less frictional than the rocks. As the glacier moves down the valley it also causes friction on the rock surfaces and pulls the weakend 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 can cause small u shaped couch valleys 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 marked by striations and ruts along the sides and bottom, as in addition to moraines and till on the floor.
U-shaped valleys can be found all over the world. 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 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 locations and then become Fjords. This is natural process that occurs when the glacier melts and it can take tens of thousands of years for these valleys to be created.
The ocean's depths are deep
U-shaped valleys are distinguished by steep sides that curve at the bottom and wide flat valley floor. They are formed by rivers valleys that were filled with glaciers during the Ice Age. The glaciers erode the valley's floor by abrasion and plucking, which cause the valley to get deeper and widen more equally than a river would. These types of features are found in mountainous regions across the world including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.
Glacial erosion of a river valley may transform it into a u-shaped one by deepening and enlarging it. The force of erosion from the glacier can also cause smaller side valleys, that are typically marked by waterfalls, to rise above the main valley. These features are known as "hanging valleys" because they are suspended above the main valley, as the glacier retreats.
These valleys are typically surrounded by forests and may contain lakes. Some valleys are dry and are used for farming, while others are flooded and may be explored as part of a hiking or kayaking excursion. Many of these valleys can be found in Alaska which is the region where melting glaciers are the most prominent.
Valley glaciers are huge streams of ice that resemble rivers and slowly move down the slopes of mountains during a glaciation. They can extend to depths of over 1000 feet, and are the dominant form in alpine areas of valley erosion. They eat away the rocks at the bottom of the valley, leaving behind depressions and holes filled with water. The lakes that result are wide and long and are located on the peaks of certain mountains.
Another type of valley, called a glacial trough is a U-shaped valley that extends into salt water and forms the Fjord. They are everywhere in the world including Norway, where they're called Fjords. They are created by melting the ice and can be found on maps of the world. They are usually distinguished by rounded sides that resemble a u shaped sectional with chaise shape in cross-section and steep sides. The walls of troughs are typically made of granite.
The slopes are steep
A U-shaped valley is an important geological feature with steep sides, high sides, and a rounded bottom. They are quite frequent in mountainous areas and are usually formed by glaciers. This is because glaciers are slow moving rivers of ice that travel downhill, scouring the land as they go. Scientists once thought that glaciers could not create valleys because they were too soft. However, now we know that they can.
Glaciers form distinctive u-shaped valleys using the techniques of plucking and abrasion. Through erosion these processes can widen, steepen, and deepen V shape valleys in rivers. They also change the slopes of the valley floor. These changes take place at the top of a glacier when it moves through the valley. This is why a U shaped valley is often larger at the top than at the bottom.
u shaped sofa sectional-shaped valleys are often filled with lakes. These lakes are called kettle lakes. They are formed in hollows which were eroded out of the rock by the glacier, or were dammed by moraine. The lake could be a temporary feature when the glacier melts or may remain when the glacier recedes. They are typically located alongside cirques.
A flat-floored Valley is another type of valley. The valley is created by streams which erode the soil. However it does not have a steep slope like a U-shaped one. They are typically found in mountainous areas and can be a lot older than other types of valleys.
There are a variety of valleys around the world, and each has a distinct appearance. The most well-known type of valley is the V-shaped, but there are some rift valleys that are U-shaped as well as. A rift valley is one that is formed in areas where the crust of the earth is separating. These are typically narrow valleys with steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.
There are many kinds of common.
U-shaped valleys are distinguished by their wide bases, unlike V-shaped ones. Glaciers are the primary cause of these valleys, which are usually found in mountain ranges. Glaciers are massive blocks made of snow and ice that erode the landscape as they slide downhill. They degrade valleys by crushing rocks with friction and abrasion. This erosion is called Scouring. When they begin to erode the landscape, glaciers create distinct shapes that resemble the letter U. These are referred to as U-shaped valleys and can be found in a variety of locations across the world.
These valleys form by glaciers that erode the valleys of rivers. The glacier's weight and slow movement can cause erosion of the valley's sides and floor, creating a distinctive u shaped sectional small-shaped shape. This process, known as glacial erosive erosion, has created some of the most beautiful landscapes on Earth.
These valleys are also called trough valleys, or glacial troughs. These valleys can be found throughout the globe, but are most often found in areas with mountains and glaciers. They can vary in dimensions from a few meters to hundreds of kilometers. They also differ in length and depth. The fluctuation in temperature will be greater the deeper the valley.
When a U-shaped valley gets filled with water, it forms a ribbon lake or fjord. The ribbon lakes form in depressions where glaciers cut away less resistant rocks. They also can form in a valley where the glacier was stopped by a moraine wall.
In addition to U-shaped valleys, the ribbon lakes can also contain glacial features, such as hanging valleys, erratics, and moraine dams. Erratics, or huge boulders, are created by a glacier as it moves. The erratics are frequently used to define the boundaries of glaciated regions.
These smaller valleys are left 'hanging" above the main valley that was created by the glacier. These valleys are not as ice-filled and are not as deep. They are formed by tributary glaciers and are often overshadowed by waterfalls.
