5 Killer Quora Answers On What Are U Shaped Valleys

what are u shaped valleys (http://www.stes.tyc.Edu.tw/xoops/modules/profile/userinfo.php?uid=2016624)?

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

The erosion of glaciers creates U-shaped valleys, caused by the plucking of rocks from the bottom and side of the valley. These valleys can be found in mountainous regions across the world.

They are created by glaciers

Glaciers are massive masses of ice that form and slide down mountains. As they erode they create U -shaped valleys that have flat floors and steep sides. These valleys differ from the valleys of rivers that are generally shaped like the letter V. Although glacial erosion can occur in many places but these valleys are distinctive of mountain regions. In fact, they are so distinct that you can determine if the landscape was formed by glaciers or by rivers.

The formation of a U-shaped gorge begins with an existing V-shaped river valley. As the glacier is eroding the landscape, it expands into the V-shaped river valley, and forms an inverted U shape. The ice also scratches the surface of the ground, causing the sides of the valley to have straight and high walls. This process is called glaciation and requires an enormous amount of strength to scour the earth this manner.

As the glacier continues to chip away at the landscape it also makes the valley more and more wide. The glacier's ice is less abrasive than the rocks. As the glacier travels down the valley, it creates abrasion on the rock surfaces and pulls the weakend rocks away from the valley walls in a process referred to as plucking. These processes combine to widen, deepen and smooth the U-shaped valley.

These processes also cause a small u shaped sofa side valley to be left 'hanging over the main valley. This valley is sometimes filled with ribbon lakes, which are formed by water rushing through the glacier. The valley is also distinguished with striations, ruts and till on the sides as well as moraines and till on the floor.

U-shaped valleys are found all over the world. They are most common in mountainous regions, such as the Andes, Alps, Caucasus, Himalaya and Rocky Mountains. In the United States they are usually located in national parks. Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana. In certain instances, these valleys extend to coastal areas and transform into fjords. This is an natural process that occurs when the glacier melts and it could take hundreds of thousands of years for these valleys to be created.

The ocean's depths are deep

U-shaped valleys are characterized by steep sides that curve at the bottom, and a wide, flat valley floor. They are formed by river valleys that have been filled by glaciers during the Ice Age. Glaciers erode valley floors by the process of abrasion and ploughing, which makes the valley widen and deepen more evenly than with rivers. These features can be found in mountainous regions all over the world including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The erosion of a river valley may transform it into a u shaped reclining sectional-shaped valley by expanding 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 features are called "hanging valleys" because they hang above the main valley when the glacier recedes.

These valleys are usually located in forests and could contain lakes. Some valleys can be used for farming, while others are flood-prone. Many of these valleys are in Alaska which is the region where melting glaciers is the most evident.

Valley glaciers are massive flowing ice like rivers that slowly creep down mountain slopes during a glaciation. They can be as deep as over 1000 feet, and are the most prevalent form of valley erosion in regions of alpine. They devour the rocks at the bottom of a valley and leave the valley with holes or depressions that are then filled with water. The lakes that result are long and narrow and are found on the tops of certain mountains.

Another type of valley, called a glacial trough, is a U-shaped valley which extends into saltwater and creates the Fjord. They are found everywhere in the world and include Norway, where they're called Fjords. These are formed by melting ice and can be seen on maps of the world. They are usually distinguished by rounded sides that resemble an U shape in cross-section as well as steep sides. The walls of troughs are typically made of granite.

They are steep

A U shaped valley is a geological formation with steep, high sides and a rounded bottom. They are quite frequent in mountainous regions and are often carved by glaciers. This is due to glaciers being slow moving rivers of ice which move downhill, scouring land as they go. Scientists used to think that glaciers wouldn't be able to carve valleys because they were so soft, but now we know that they can create these forms.

Glaciers create distinctive u-shaped valleys using the processes of plucking as well as abrasion. Through erosion these processes may broaden, steepen, and deepen V shaped river valleys. They also alter the slopes of the valley floor. These changes happen at the front of a glacier as it traverses a valley. This is the reason why the top of U-shaped valleys is usually larger than the lower.

Sometimes, U-shaped valleys may be filled with lakes. These are referred to as kettle lakes and they form in hollows that were created out of the rock by the glacier, or were dammed by moraine. The lake can be a temporary feature as the glacier melts, or it may remain after the glacier recedes. These lakes are usually found in conjunction with cirques.

Another kind of valley is one with a flat floor. It is formed by streams that erode the soil. However, it does not have a steep slope as a U-shaped one. They are typically located in mountainous areas and are often older than other kinds of valleys.

There are many different types of valleys around the world and each one has its own distinct appearance. The most well-known type of valley is the V-shaped one, but there are also rift and U-shaped valleys. A rift valley is formed in areas where the earth's crust 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. Glaciers are the main cause of these valleys, which are typically located in mountain ranges. Glaciers are massive blocks of snow and ice that alter landscapes as they move downwards. They erode valleys through friction and abrasion. This erosion is called the scouring. As they erode the landscape, glaciers create a distinctive shape resembling the letter U. These valleys, also referred to as U-shaped valleys, can be found in many locations around the globe.

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

These valleys are often called glacial troughs or trough valleys. These valleys are found all over the globe, but are most often found in regions with glaciers and mountains. They range in dimensions from a few meters to several hundred kilometers. They also vary in length and depth. The fluctuation in temperature will be higher the deeper the valley.

When a U-shaped valley is filled with water, it develops into a ribbon lake or fjord. The ribbon lakes develop in the valleys where the glacier eroded the rock that was less resistant. They also can form in a valley where the glacier was stopped by a moraine wall.

U-shaped valleys can also contain other glacial features, like hanging valleys, moraine dams, and Erratics. Erratics are massive rocks that were left behind by glaciers during their movement. They are commonly used to mark the boundaries of glaciated areas.

Hanging valleys are smaller side valleys hanging above the main valley formed by the glacier. They aren't as deep as the main valley, and they contain less ice. They are carved by glaciers that tributary to the main valley and are usually capped by waterfalls.
