Five Killer Quora Answers On What Are U Shaped Valleys

what are u shaped valleys - source web page -?

A U-shaped valley is an edifice of geology that has steep, high sides as well as flat or rounded valley bottom. They are the result of glaciation and are frequently home to lakes, rivers and sand traps found on golf courses kettle lakes (water hazards), and other such natural features.

The erosion of glaciers creates U-shaped valleys by plucking rocks from the side and bottom of the valley. These valleys are common in mountainous regions all over the world.

They are created by glaciers

Glaciers are massive masses of ice that form and move down mountains. When they melt 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 a V. Although glacial erosion can happen anywhere however, these valleys tend be more prevalent in mountainous areas. They are so distinct that it is easy to tell whether the landscape was created by rivers or glaciers.

The formation of a U-shaped gorge begins with an existing V-shaped river valley. As the glacier melts, it encroaches upon the V-shaped valley of the river, and forms an inverted U-shape. The ice also damages the surface of the land, which causes the valley's sides to have straight and high walls. This process is referred to as glaciation, and it takes an enormous amount of strength to scour earth in this manner.

As the glacier continues to degrade the landscape, it makes the valley wider and deeper. This is because the ice has less frictional resistance than the surrounding rocks. As the glacier moves down 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 combine to broaden, 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 may be filled with ribbon lakes created when water flows through the glacier. The valley is also characterized by striations and ruts along the sides and bottom, as well as till and moraines on the floor.

U-shaped valleys are found across the globe. They are common in mountainous regions, 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 areas and transform into fjords. This is a natural process that happens when the glacier melts and it can take tens of thousands of years for these valleys to be created.

They are deep

U-shaped valleys have steep sides that curve into the bottom and wide flat valley floors. They are formed in river valleys that have been filled by glaciers during the ice age. Glaciers degrade the valley floor through abrasion and plucking, which cause the valley to deepen and broaden more evenly than a river could. These types of features are found in mountainous regions around the world including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

Glacial erosion of a valley in the river can transform it into a u-shaped valley, deepening and enlarging it. The force of erosion from the glacier can also create smaller side valleys, that are typically marked by waterfalls, to rise above the main valley. These features are called "hanging valleys" because they hang above the main valley when the glacier recedes.

These valleys are typically covered by forests, and can contain lakes. Some valleys are dry and are used for farming, whereas others are flooded and can be visited as part of a kayaking or hiking trip. A large number of these valleys are in Alaska in the region where glacial melt is most pronounced.

Valley glaciers are massive river-like flows of ice that slowly creep down the slopes of mountains during a glaciation. They can extend to depths of more than 1000 feet and are the most common type of valley erosion in regions of alpine. They consume the rock on the bottom of a valley leaving the valley with holes or depressions that are then filled with water. The lakes that result are narrow and long and can be found on the tops of certain mountains.

A glacial trough is yet another kind of valley. It is a U form valley that extends out into the salt water to create a Fjord. These are typical in Norway, where they are called fjords, but are also found in other parts of the world. They are created by melting glaciers and are visible on maps of the globe. They are distinguished by their steep sides and rounded sides in the U-shape. The walls of troughs are usually made from granite.

The slopes are steep

A U shape valley is a formation of geology with high, steep sides and a smooth bottom. They are very frequent in mountainous areas and are usually carved by glaciers. This is due to glaciers being slow moving rivers of ice which move downhill, scouring the land as they move. Scientists once thought that glaciers wouldn't be able to carve valleys due to being so soft. However, now we know they can.

Glaciers create distinctive u shaped settees-shaped valleys using the techniques of plucking and abrasion. These processes widen, steepen and deepen V-shaped river valleys to a U shape through erosion. They also change the slopes of the valley floor. These changes occur at the front of a glacier as it moves through the valley. This is the reason why a U shape valley is usually wider at the top than at the bottom.

Sometimes, U-shaped valleys may 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 can be a temporary feature when the glacier melts, or can remain after the glacier recedes. They are often associated with cirques.

A flat-floored Valley is another kind of valley. It is a valley that is formed by streams that degrade the soil, but it doesn't have as steep of a slope as an U-shaped valley. They are usually found in mountainous areas and can be older than other types of valleys.

There are many types of valleys in the world. Each has its own unique appearance. The most popular is a V-shaped one, however, other forms include sofa u shape-shaped valleys as well as rift valleys. A rift valley occurs when the earth's surface is splitting apart. They are typically narrow valleys with steep sides. The Nant Ffrancon valley in Snowdonia, Wales is a good illustration of this.

There are a variety of common.

U-shaped valleys are characterized by their broad bases unlike V-shaped ones. Glaciers are responsible for creating these valleys, which are generally located in mountain ranges. Glaciers are massive blocks of snow and ice that alter landscapes as they slide downwards. They degrade valleys by friction and abrasion. This is referred to as the scouring. The glaciers break up the landscape in a distinctive u shaped couch with recliners-shaped design. These valleys, also referred to as U-shaped Valleys, can be found in a variety of locations around the globe.

The formation of these valleys takes place when glaciers alter existing valleys of rivers. The glacier's slow movements and weight is able to erode the valley's floor and sides, creating a distinctive U shape. This process is known as glacial erosion, and has resulted in some of the most breathtaking landscapes on Earth.

These valleys are sometimes called trough valleys or glacial troughs. They are found throughout the globe, but are particularly found in regions with glaciers and mountains. They range in size from a few metres to several hundred kilometers. They can also vary in length and depth. The deeper the valley is, the larger the fluctuation of temperature will be.

When a U-shaped valley gets filled with water, it forms a ribbon lake or fjord. The ribbon lakes are formed in depressions where glaciers cut away less resistant rocks. They can also form within valleys, in which the glacier is stopped by walls.

Aside from ribbon lakes, U-shaped valleys may also have glacial features such as erratics, hanging valleys and moraine dams. Erratics, also known as massive boulders, are deposited by a glacier as it moves. The erratics can be used to define the boundaries between glaciated areas.

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