Five Killer Quora Answers To What Are U Shaped Valleys

What Are U Shaped Valleys?

A U-shaped valley is a geological formation with high, steep sides and a rounded or flat valley bottom. They are the result of glaciation and are frequently filled with lakes, rivers and sand traps found on golf courses kettle lakes (water hazards) and other natural features.

The process of glacial erosion creates U-shaped valleys when the rocks are removed from the sides and bottom of the valley. These valleys are found in mountainous regions around the globe.

Glaciers are responsible for forming them

Glaciers are massive bodies of ice that are formed on mountains and then move down them. When they degrade the landscape, they create U-shaped valleys that have flat floors and steep sides. These are different from the river valleys, which are usually shaped in the shape of the shape of a V. While glacial erosion can occur anywhere, these valleys tend to be more prevalent in mountainous areas. They are so distinct that you can tell whether the landscape has been shaped by glaciers or rivers.

The formation of a u shaped sofa -shaped valley starts by creating an V shape river valley. As the glacier erodes the landscape it encroaches on the V-shaped river valley and creates an inverted U shape. The ice also scratches the surface of the land, causing the valley's sides to have high and straight walls. This process is known as glaciation and it requires the use of a lot of force to move the earth this way.

As the glacier continues to degrade the landscape it also makes the valley more and more wide. The glacier's ice is less frictional than the rocks. As the glacier moves through the valley it also causes abrasion to the rock surfaces. This pulls the weaker rocks away from the valley walls in a process called plucking. These processes are used together to smooth, widen and deepen the U-shaped valley.

These processes also cause a tiny side valley to be left 'hanging' above the main valley. The valley may be filled with ribbon lakes created when water flows through the glacier. The valley is also distinguished with striations and ruts, till on the sides, as well as moraines and till on the floor.

The world is full of U-shaped valleys. They are most often found in mountainous regions 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 Glacier National Park and the Nant Ffrancon Valley in Wales. In certain instances, valleys can extend to the coast and turn into 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 slop in at the base and wide 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 by abrasion and plucking, which cause the valley to grow deeper and expand more evenly than a river would. These features are found around the globe in mountainous regions including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The glacial erosion of a valley may transform it into a U-shaped valley, by deepening and expanding it. The glacier's erosive force can also cause smaller side valleys, which are often identified by waterfalls, to float above the main valley. These are referred to as "hanging valleys", because they are suspended above the main valley, as the glacier recedes.

These valleys are usually covered by forests, and can contain lakes. Some valleys are dry and utilized for farming, while others are swamped and can be visited as part of a kayaking or hiking excursion. Many of these valleys are located in Alaska which is the region where glacial melting is most evident.

Valley glaciers are massive river-like flows that slowly slide down the slopes of mountains. They can be as deep as 1000 feet and are the predominant form in alpine areas of valley erosion. They eat the rocks at the bottom of the valley, causing depressions and holes that are filled with water. The resulting lakes are wide and thin, and can be found in the peaks of some mountains.

Another type of valley, called a glacial trough is a U-shaped valley that extends into salt water and forms a fjord. They can be found everywhere in the world including Norway which is where they're known as Fjords. They are created by melting ice and are visible on maps of the world. They are usually distinguished by rounded sides that mimic an leather sectional u shaped shape in cross-section and steep sides. The walls of troughs are usually made from granite.

The slopes are steep

A U-shaped valley is a geomorphological feature that has steep, high sides and a flat base. They are very 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 go. Scientists used to believe that glaciers couldn't carve valleys due to being so soft. But now, we know that they are able to.

Glaciers create distinctive u-shaped valleys through the processes of plucking and abrasion. These processes broaden, steepen and deepen V-shaped valleys into the U shape by eroding. They also change the slopes of the valley floor. These changes take place in the front of a glacier when it traverses the valley. This is why the U shaped valley is often wider at the top and narrower at the bottom.

Sometimes, U-shaped valleys can 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 may be a temporary feature, as the glacier melts, or it may remain after the glacier has receded. They are typically associated with cirques.

Another type of valley is a flat-floored one. This is a valley formed by streams that degrade the soil, but it isn't the same slope as the U-shaped valley. They are usually found in mountainous areas and can be much older than other types.

There are many different types of valleys in the world and each one has a unique appearance. The most well-known type of valley is the V-shaped one, however there are also U-shaped and rift valleys. A rift valley is one that is formed in areas where the crust of the earth is separating. These are typically narrow valleys that have steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good illustration of this.

They are broad

Contrary to V-shaped valleys, U-shaped valleys have broad bases. Glaciers are the primary cause of these valleys, which are typically found in mountain ranges. Glaciers are huge blocks of snow and ice that alter landscapes as they move downwards. They cause valleys to be eroded by friction and erosion. This erosion is called Scouring. The glaciers erode the landscape in a distinctive U-shaped pattern. These are referred to as U-shaped valleys and are found in a variety of locations across the globe.

The formation of these valleys happens when glaciers degrade existing valleys of rivers. The glacier's slow motion and weight erodes the valley's sides and floor and creates a distinctive U shape. This process, referred to as glacial erosive erosion has resulted in some of the most stunning landscapes on Earth.

These valleys are also called trough valleys, or glacial troughs. These valleys are found all over the world, but especially in areas with mountains and glaciers. They can range in dimensions from a few meters to several hundred kilometers. They also differ in depth and length. The deeper the valley, the larger the fluctuation of temperature will be.

When a U-shaped valley is filled with water, it develops into a ribbon lake or fjord. The ribbon lakes are formed in depressions where glaciers eroded less resistant rock. They can also form within a valley where the glacier has been stopped by the wall.

In addition to U-shaped valleys, ribbon lakes can also contain glacial features such as hanging valleys, erratics and moraine dams. Erratics are massive boulders that were deposited by glaciers during their movement. The erratics are often used to mark the boundaries of glaciated regions.

Hanging valleys are smaller side valleys that are hanging above the main valley created by the glacier. These valleys are not as deep as the main valley, and they contain less ice. These valleys are carved out by tributary ice and are often overshadowed by waterfalls.
