what are u shaped valleys [visit this weblink]?

A U-shaped Valley is a geological formation that has steep, high sides as well as flat or rounded valley bottom. These valleys are formed by glaciation. They usually contain lakes, rivers, sandtraps on golf course kettle lakes (water hazards) or other natural features.

Glacial erosion creates U-shaped valleys when the rocks are removed from the sides and the bottom of the valley. These valleys are found in mountainous regions all over the globe.

They are formed by glaciers

Glaciers are massive bodies of ice that are formed on mountains, and then move down them. As they erode, they create U shaped valleys that have flat floors and steep sides. These are distinct from river valleys, which are usually shaped like the letter V. While glacial erosion can occur in many places however, these valleys are typical of mountain regions. They are so distinct that you can determine if the landscape was formed by glaciers or rivers.

The formation of a U-shaped valley starts with an existing V-shaped river valley. As the glacier erodes and encroaches on the V-shaped valley of the river, and forms an U-shaped inverted form. The ice also scour the surface of the land, causing high and straight walls along the sides of the valley. This is known as glaciation and it requires an enormous amount of strength to scour earth in this manner.

As the glacier continues to chip away at the landscape, it makes the valley deeper and wider. The glacier's ice is less abrasive than the 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 valley walls, a process known as plucking. These processes are combined to widen, deepen and smooth the U-shaped valley.

These processes also cause a tiny side valley to be left 'hanging' above the main valley. The valley could be filled with ribbon lakes that are formed when water flows through the glacier. The valley is also marked by striations, ruts and striations on the sides, as also moraines and till on the floor.

The world is filled with U-shaped valleys. They are prevalent in mountainous areas, including the Andes, Alps, Caucasus, Himalaya 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 cases the valleys can extend to coastal locations and transform into Fjords. This is a natural phenomenon that occurs when the glacier melts. It could take thousands of years to create these valleys.

The ocean's depths are deep

U-shaped valleys have steep sides that slop towards the base, and large, flat valley floors. They are formed by river valleys that were filled with glaciers during the Ice Age. The glaciers erode valley floors via cutting and abrasion which makes the valley widen and expand more evenly than with rivers. These types of features are common throughout the world in mountainous areas including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The erosion of glaciers in a valley may transform it into a U-shaped valley, by expanding and deepening it. The glacier's erosive force can also create smaller side valleys, which are usually characterized by waterfalls, to float above the main valley. These features are known as "hanging valleys" due to the fact that they are hung over the main valley when the glacier recedes.

These valleys are often covered in forest and may contain lakes. Some valleys are dry and are utilized for farming, while others are flooded and can be visited as part of a hike or kayaking trip. A large number of these valleys are in Alaska which is where glacial melt is most pronounced.

Valley glaciers are huge u shaped sofa flowing ice like rivers that slowly creep down the slopes of mountains during a glaciation. They can reach depths over 1000 feet and are the predominant form in alpine areas of valley erosion. They eat the rocks that lie at the bottom of the valley, leaving behind depressions and holes filled with water. The lakes that result are wide and long, and can be found on the peaks of certain mountains.

A glacial trough is a different type of valley. It is a U form valley that extends out into the salt water to form the Fjord. They can be found all over the world including Norway which is where they're known as Fjords. They are created by melting the ice and can be found on maps of the world. They are characterized by steep sides and rounded sides in the U-shape. The trough walls are generally constructed from granite.

They are a bit steep

A U shaped valley is a type of formation with steep, high sides and a smooth bottom. They are frequent in mountainous areas and are usually carved by glaciers. This is because glaciers move slowly downhill and then scour the land. Scientists used to believe that glaciers couldn't create valleys due to the fact that they are so soft but now we know they can create these shapes.

Glaciers form distinctive small u shape sofa-shaped valleys through the processes of abrasion as well as plucking. Through erosion these processes can broaden, steepen, and deepen V shape valleys of rivers. The slopes of the valley bottom are also altered. These changes occur in the front of the glacier as it turns into the valley. This is the reason why the sofa u shaped shaped valley is often wider at the top than at the bottom.

U-shaped valleys are often filled with lakes. These lakes are known as kettle lakes. They form in hollows that were created out of the rock by the glacier or dammed by moraine. The lake may be a temporary feature while the glacier melts, or it remains even after the glacier has receded. These lakes are usually found in conjunction with cirques.

A flat-floored valley is another type of valley. This valley is formed by streams which erode the soil. However it does not have a steep slope as the oversized u shaped sectional-shaped ones. They are often found in mountainous areas and can be a lot older than other kinds of valleys.

There are various types of valleys in the world. Each has its own distinctive appearance. The most well-known is a V-shaped one, but there are other varieties, including U-shaped valleys as well as the rift valleys. A rift valley occurs when the earth's surface is splitting apart. They are typically narrow valleys that have steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good example of this.

They are wide

In contrast to V-shaped valleys U-shaped valleys have broad bases. They are usually found in mountains and are formed by glaciers. Glaciers are huge blocks of snow and ice that erode the landscape as they slide downhill. They cause valleys to be eroded by friction and abrasion. This erosion is known as scouring. As they erode the landscape, the glaciers create an unusual shape that resembles a letter U. These valleys, often referred to as U-shaped valleys, can be found in many locations around the globe.

These valleys are formed when glaciers degrade valleys of rivers. The glacier's weight and slow movement can cause erosion of the valley floor and sides, creating a distinctive U-shaped shape. This process is known as glacial erosion, and has resulted in some of the most breathtaking landscapes on Earth.

These valleys may also be called trough valleys, or glacial troughs. They are found all over the globe, but are particularly found in regions that have glaciers and mountains. They can vary in size from a few meters to hundreds of kilometers. They also differ in length and depth. The deeper the valley the more intense the fluctuation of temperature will be.

A ribbon lake or fjord is formed when a U-shaped valley is filled with water. The ribbon lakes form in depressions where glaciers have eroded less resistant rock. They can also form in a valley in which the glacier is stopped by walls.

In addition to ribbon lakes, u shaped couch recliner-shaped valleys can also contain glacial features, such as hanging valleys, erratics, and moraine dams. Erratics are huge boulders that were dumped by the glacier during its movement. They are commonly used to mark the boundaries of glaciated areas.

These smaller valleys are left hanging" above the main valley that was created by the glacier. They aren't as deep as the main valley and they contain less ice. They are carved by tributary glaciers, and are usually covered by waterfalls.
