what are u shaped valleys (highwave.kr`s statement on its official blog)?

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

Glacial erosion causes U-shaped valleys, caused by the plucking of rocks from the sides and bottom of the valley. These valleys are common in mountainous regions across the world.

Glaciers are the primary reason for forming them

Glaciers are massive bodies of ice which form on mountains and then move down them. When they melt 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 locations but these valleys are characteristic of mountain areas. They are so distinct that it is easy to tell whether the landscape was created by glaciers or rivers.

The process of creating a U shape valley begins by creating a V shaped river valley. As the glacier melts it, it expands into the V-shaped valley of the river and creates an inverted U-shape. The ice also scour the land's surface creating straight and high walls on the sides of valley. This process is known as glaciation and requires a great deal of strength to move the earth in this manner.

As the glacier continues eroding the landscape, it also makes the valley wider and deeper. The ice is less frictional than the rocks. As the glacier moves through the valley, it creates scratches on the rocks and pulls the weaker rocks away from the valley wall in a process known as plucking. These processes help to smooth, widen and deepen the U-shaped valley.

This process can cause a small valley to 'hang above the main one. The valley could be filled with ribbon lakes that are formed when water flows through the glacier. The valley is also characterized by striations, ruts, and till on the sides, as well as moraines and till on the floor.

The world is filled with U-shaped valleys. They are most often found in mountainous areas, such as the Andes Mountains, Alps Mountains, Himalaya Mountains, Caucasus Mountains, and Rocky Mountains. In the United States, they are often located in national parks. Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana. In some cases valleys can expand to coastal areas and become fjords. This is an natural process that occurs when the glacier melts and it can take many thousands of years for these valleys to be formed.

They are deep

U-shaped valleys have steep sides that slop into the bottom and large flat valley floors. They are created in valleys in rivers that were filled by glaciers during the glacial era. Glaciers degrade the valley floor by abrasion and plucking which causes the valley to deepen and broaden more evenly than a river could. These features can be found in mountainous regions across the world including the Andes Mountains, Alps Mountains, Himalayas Mountains, Rocky Mountains and New Zealand.

The erosion of glaciers in the valley could transform it into a u shaped sectional couch-shaped valley by enlarging and deepening it. The force of erosion from the glacier can also create smaller side valleys, which are usually identified by waterfalls, to hang above the main valley. These are referred to as "hanging valleys", because they are hung over the main valley, as the glacier retreats.

These valleys could be covered in forest and may contain lakes. Some valleys are dry and are used for farming, whereas others are flooded and can be explored as part of a kayaking or hiking trip. Many of these valleys can be found in Alaska which is the region where melting glaciers are the most prominent.

Valley glaciers are massive, like river-like flows that slowly slide down mountain slopes. They can extend to depths of more than 1000 feet and are the most common type of valley erosion in the alpine regions. They consume the rocks that lie at the bottom of the valley, causing depressions and holes that are filled with water. The lakes that result are wide and thin, and can be found in the peaks of some mountains.

Another kind of valley, called a glacial trough, is a U-shaped valley that extends into salt water and creates an Fjord. They can be found all over the globe and include Norway which is where they're known as Fjords. These are formed by melting ice and are visible on maps around the globe. They are characterized by steep sides and rounded sides with the U-shape. The walls of troughs are typically constructed from granite.

They are sloping

A U form valley is a geological formation with steep, high sides and a rounded bottom. Glaciers are the cause of many of these valleys. They are frequent in mountainous regions. This is due to glaciers being slow-moving rivers of ice which move downhill, scouring land as they move. Scientists used to think that glaciers wouldn't be able to carve valleys due to the fact that they are so soft, but now we know they do create these forms.

Glaciers cut distinctive u shaped sectional small-shaped valleys by using the processes of plucking and abrasion. Through erosion these processes can broaden, steepen, and deepen V shaped valleys of rivers. The valley's slopes bottom are also altered. These changes take place in the front of a glacier as it moves through the valley. This is why the U form valley is typically wider at the top than at the bottom.

U-shaped valleys can be filled with lakes. These are referred to as kettle lakes. 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 while the glacier melts, or it remains when the glacier recedes. They are typically found in conjunction with cirques.

Another kind of valley is a flat-floored one. The valley is created by streams which erode the soil. However, it does not have a steep slope like a U-shaped one. They are often located in mountainous areas, and can be older than other kinds of valleys.

There are many different types of valleys around the world and each one has a distinct appearance. The most well-known is a V-shaped one, but there are other varieties, including U-shaped valleys and rift valleys. A rift valley occurs when the earth's surface is splitting apart. These are typically narrow valleys with steep sides. This is evident in the Nant Ffrancon Valley, located in Snowdonia.

They are broad

U-shaped valleys are characterized by their wide bases, unlike V-shaped ones. Glaciers are responsible for creating these valleys, which are typically located in mountain ranges. Glaciers are huge u shaped sectional blocks made of snow and ice that degrade landscapes as they slide downwards. They erode valleys by crushing rocks with friction and the abrasion. This process is referred to as the scouring. The glaciers erode the landscape in a distinctive U-shaped pattern. These valleys, also referred to as U-shaped valleys, can be found in many places around the world.

These valleys form by glaciers that erode the valleys of rivers. The glacier's weight and slow movement erode the valley's sides and floor creating a unique U-shaped shape. This process, also known as glacial erosive erosion, has resulted in some of the most stunning landscapes on Earth.

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

When a grey u shaped sectional-shaped valley is filled with water, it creates a ribbon lake or fjord. The ribbon lakes develop in the valleys where the glacier eroded the rock with less resistance. They can also develop in valleys in which the glacier was stopped by a moraine wall.

Apart from U-shaped valleys, the ribbon lakes can also be filled with glacial features like hanging valleys, erratics, and moraine dams. Erratics are massive rocks that were left behind by the glacier during its movement. The erratics are used to define the boundaries between glaciated regions.

Hanging valleys are smaller side valleys that are hanging above the main valley formed by the glacier. These valleys aren't as deep as the main valley and they have less ice. These valleys are carved out by tributary ice, and are usually topped by waterfalls.
