5 Killer Quora Answers On What Are U Shaped Valleys

What Are U Shaped Valleys?

A U-shaped valley is an edifice of geology that has high, steep sides and flat or rounded valley bottom. These valleys are created by glaciation. They often contain lakes rivers, sandtraps, sandtraps on golf course, kettle lakes (water hazards) or other natural features.

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

Glaciers are responsible for forming them.

Glaciers are massive bodies of ice that are formed on the tops of mountains and then slide down them. As they erode, they create U -shaped valleys that have flat floors and steep sides. These valleys are distinct from river valleys that tend to be shaped in the shape of an X. While glacial erosion can occur anywhere, these valleys tend to be more common in mountainous areas. In fact, they are so distinct that you can tell whether the landscape was created by glaciers or rivers.

The formation of a U-shaped gorge begins with an existing V-shaped river valley. As the glacier erodes the landscape it encroaches on the V-shaped river valley and produces an inverted U shape. The ice also scoures the surface of the land, causing the sides of the valley to have high and straight walls. This process is known as glaciation and requires the strength of a lot to move the earth in this manner.

As the glacier continues to erode the landscape, it makes the valley wider and deeper. This is due to the fact that ice has a lower frictional resistance than the surrounding rocks. As the glacier moves through the valley, it also causes abrasion to the surfaces of the rocks. This pulls the weaker rocks away from the valley walls in a process called plucking. These processes work together to increase the width, depth and smooth the U-shaped valley.

This process 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 distinguished by striations and ruts along the sides and bottom, as well as till and moraines on the floor.

The world is filled with U-shaped valleys. They are common in mountainous regions, including the Andes, Alps, Caucasus, Himalaya and Rocky Mountains. In the United States they are usually located in national parks. Examples include Glacier National Park and the Nant Ffrancon Valley in Wales. In some instances valleys can extend to the coast and turn into fjords. This is a natural process 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 in at the base and wide flat valley floors. They are formed by river valleys which have been filled with glaciers during the Ice Age. Glaciers erode the valley floor by abrasion and plucking which causes the valley to get deeper and widen more equally than a river would. These types of features are found in mountainous regions all over the globe including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The erosion of glaciers in a valley may transform it into a U-shaped one by enlarging and deepening it. The force of the glacier's erosion can also cause smaller side valleys that are typically identified by waterfalls, to float above the main valley. These types of valleys are known as "hanging valleys" because they are hung above the main valley when the glacier retreats.

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

Valley glaciers are massive river-like flows of ice that slowly creep down the slopes of mountains during a glaciation. They can reach depths over 1000 feet, and are the dominant form in the alpine regions of valley erosion. They devour the rock on the bottom of a valley leaving the area with depressions or holes, which are then filled with water. The lakes that result are wide and long and are located on the peaks of certain mountains.

Another kind of valley, called a glacial trough is a U-shaped trough which extends into saltwater and creates an Fjord. They are prevalent in Norway, where they are referred to as fjords, but are also found in other regions of the world. These are formed by melting the ice and can be found on maps of the world. They are distinguished by steep sides and rounded sides in an U-shape. The walls of the troughs are usually made from granite.

The slopes are steep.

A U-shaped valley is a geomorphological feature with steep sides, high sides and a rounded base. Glaciers are responsible for many of these valleys. They are frequent in mountainous areas. This is due to glaciers' slow movement downhill and then scour the land. Scientists once believed that glaciers could not create valleys because they were too soft. However, now we know they can.

Glaciers create distinctive U-shaped valleys by the process of abrasion as well as plucking. Through erosion these processes may broaden, steepen, and deepen V shape valleys of rivers. They also alter the slopes of the valley floor. These changes take place at the front of the glacier as it moves into a valley. This is why the U shaped valley is often wider at the top than at the bottom.

Sometimes, U-shaped valleys may be filled with lakes. These are referred to 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 could be a temporary feature as the glacier melts, or it may remain even after the glacier has receded. They are usually found in conjunction with cirques.

Another type of valley is one with a flat floor. The valley is created by streams which erode the soil. However it does not have a steep slope as the U-shaped ones. They are usually found in mountainous areas and can be much older than other types.

There are a variety of valleys across the globe, and each has its own distinct appearance. The most well-known kind of valley is the V-shaped, but there are some rift valleys that are U-shaped as well as. A rift valley is formed when the earth's surface is breaking 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

In contrast to V-shaped valleys U-shaped valleys have broad bases. They are typically found in mountain ranges and are shaped by glaciers. Glaciers are huge blocks of ice and snow that erode landscapes as they move downwards. They erode valleys through friction and abrasion. This is referred to as the scouring. When they begin to erode the landscape, the glaciers create a distinctive shape resembling a letter U. These valleys are known as U-shaped valleys and can be found in a variety of locations across the globe.

These valleys are formed when glaciers degrade valleys of rivers. The glacier's slow movement and weight is able to erode the valley's floor and sides creating a distinct U shape. This process, also known as glacial erosive erosion, has resulted in some of the most stunning landscapes on Earth.

These valleys are sometimes referred to as glacial troughs or troughs. They are found all over the globe, but are particularly found in areas with glaciers and mountains. They can vary in sizes ranging from a few meters to hundreds of kilometers. They also differ in depth and length. The deeper the valley, the larger the fluctuation of temperature will be.

If a U-shaped gorge is filled with water, it forms a ribbon lake or fjord. The ribbon lakes form in depressions where glaciers eroded less resistant rocks. They can also form in a valley where the glacier was stopped by a wall of moraine.

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

These smaller valleys hang" above the main valley created by the glacier. These valleys are not as deep than the main valley and they are ice-free. They are formed by tributary glaciers and are usually overshadowed by waterfalls.
