what are u shaped valleys (read this blog post from jejucordelia.com)?

A sofa u shaped-shaped valley is an 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 sectional-shaped valleys as rocks are removed from the sides and bottom of the valley. These valleys are found in mountainous regions all over the globe.

They are formed by glaciers

Glaciers are huge bodies of ice that form and slide down mountains. As they erode they create U shape valleys with flat floors and steep sides. These valleys differ from the valleys of rivers, which are usually designed to look like the letter V. While glacial erosion can occur in many places however, these valleys are distinctive of mountain regions. They are so distinct that you can tell whether the landscape was shaped by glaciers or rivers.

The formation of a U-shaped valley begins with an existing V-shaped river valley. As the glacier degrades the landscape it encroaches on the V-shaped river valley and produces an inverted U-shaped. The ice also scratches the surface of the land, which causes the sides of the valley to have high and straight walls. This is known as glaciation, and it takes the use of a lot of force to move the earth in this manner.

As the glacier continues to erode the landscape it also makes the valley wider and deeper. The glacier's ice is less frictional than the rocks. As the glacier moves through the valley it also causes scratches on the rocks and pulls the weakend rocks away from the valley wall through a process called plucking. These processes help to broaden, smoothen and deepen the U-shaped valley.

This process also causes small valleys to "hang above the main one. The valley could be filled with ribbon lakes created when water flows through the glacier. The valley is also marked by 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 most common in mountainous areas, including the Andes, Alps, Caucasus, Himalaya 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 instances the valleys can extend to coastal locations and then become fjords. This is a natural phenomenon that occurs when the glacier melts. It can take thousands of years to create these valleys.

They are deep

U-shaped valleys have steep sides that curve into the bottom and wide flat valley floors. They are formed by river valleys that were filled with glaciers during the Ice Age. The glaciers erode the valley's floor by plucking and abrasion and cause the valley to deepen and broaden more evenly than a river could. These types of features are found in mountainous regions all over the world, including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The erosion of the glacier in a valley can change it into a U-shaped valley by expanding and deepening it. The erosive force of the glacier also causes smaller side valleys to hang above the main valley, that is typically marked by waterfalls. These are referred to as "hanging valleys" because they are suspended above the main valley when the glacier recedes.

These valleys are typically covered by forests, and can contain lakes. Some valleys can be used for agriculture while others are flood-prone. A large number of these valleys are located in Alaska which is where glacial melt is the most evident.

Valley glaciers are massive flowing ice like rivers that slowly move down the slopes of mountains during a glacier. They can extend to depths of more than 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, leaving behind depressions and holes that are filled with water. The lakes that result are long and narrow, and can be located on the peaks of certain mountains.

Another kind of valley, called a glacial trough is a U-shaped trough that extends into salt water and creates the fjord. They are found all over the world, including Norway which is where they're known as fjords. They are created by melting ice and can be seen on maps around the globe. They are usually characterized by rounded sides that resemble a U shape in cross-section and steep sides. The trough walls are generally carved out of granite.

They are a bit steep

A U-shaped valley is a geological feature that has steep sides, high sides and a rounded bottom. Glaciers are responsible for many of these valleys. They are frequent in mountainous regions. This is due to glaciers being slow-moving rivers of ice which move downhill, scouring the land as they move. Scientists once believed that glaciers couldn't carve valleys because they were so soft. But now, we know that they can.

Glaciers create distinctive u-shaped valleys by using the processes of plucking as well as abrasion. Through erosion these processes can widen, steepen, and deepen V shape river valleys. The slopes of the valley bottom are also altered. These changes take place at the front of the glacier when it turns into the valley. This is the reason why the U form valley is typically wider at the top than at the bottom.

U-shaped valleys are often filled with lakes. These kettle lakes form in hollows caused by erosion of the glacier or surrounded by the moraine. The lake could be a temporary feature while the glacier melts or may remain even after the glacier has receded. They are usually located in conjunction with cirques.

A flat-floored valley is another type of valley. It is formed by streams that erode the soil. However it does not have a steep slope like the U-shaped ones. They are typically located in mountainous areas and can be a lot older than other types of valleys.

There are many types of valleys around the world. Each has its own distinct appearance. The most common is a V-shaped valley but there are other varieties, including U-shaped valleys as well as the rift valleys. A rift valley forms where the earth's surface is splitting into two. They are usually 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 broad bases unlike V-shaped ones. They are most often found in mountain ranges and are shaped by glaciers. Glaciers are massive blocks of snow and ice that degrade the landscape as they move downhill. They erode valleys by crushing rocks through friction and the abrasion. This is referred to as scouring. As they erode the landscape, glaciers create an unusual shape that resembles the letter U. These valleys are referred to as u shaped leather sofas-shaped valleys and are found in many locations around the world.

The formation of these valleys takes place when glaciers degrade existing river valleys. The glacier's slow movements and weight degrades the valley's floor and sides and creates a distinctive U shape. This process, known as glacial erosive erosion, has created some of the most beautiful landscapes on Earth.

These valleys are often called glacial troughs or trough valleys. They are common throughout the globe, but are particularly found in areas with glaciers and mountains. They can vary in dimensions from a few meters to hundreds of kilometers. They also differ in depth and length. The deeper the valley is, the larger the fluctuation of temperature will be.

A fjord or ribbon lake is formed when a U-shaped gorge fills with water. The ribbon lakes form in depressions where glaciers have eroded less resistant rock. They can also develop in valleys where the glacier was stopped by a wall of moraine.

U-shaped valleys can also contain other glacial features, like moraine dams, hanging valleys and erratics. Erratics are massive boulders that were deposited by the glacier during its movement. The erratics are often used to mark the boundaries of glaciated regions.

Hanging valleys are smaller side valleys that are left 'hanging' above the main valley created by the glacier. These valleys contain less ice and aren't as deep. These valleys are cut by tributary ice and are often covered by waterfalls.
