A Brief History History Of What Are U Shaped Valleys

Description

What Are U Shaped Valleys?

A U-shaped valley is a geological formation with high, steep sides and a rounded 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.

Glacial erosion creates U-shaped valleys as rocks are removed from the sides and the bottom of the valley. These valleys are found in mountainous regions around the world.

Glaciers are responsible for forming them.

Glaciers are huge bodies of ice that form and slide down mountains. As they erode the landscape they form U-shaped valleys with flat floors and steep sides. These valleys are distinct from river valleys which tend to be shaped in the shape of a V. While glacial erosion can occur everywhere however, these valleys tend be more prevalent in mountainous regions. They are so distinct that you can tell whether the landscape has been shaped by glaciers or rivers.

The formation of a U-shaped valley starts with an existing V-shaped river valley. As the glacier degrades the landscape, it encroaches upon the V-shaped river valley and creates an inverted U-shaped shape. The ice also scratches the surface of the land, causing the sides of the valley to have straight and high walls. This process is referred to as glaciation, and it requires an enormous amount of strength to move the earth in this manner.

As the glacier continues to erode the landscape, it makes the valley bigger and deeper. The glacier’s ice is less frictional than the rocks. As the glacier moves through the valley, it also causes abrasion of the surfaces of the rocks. This pulls the less durable rocks away from the valley walls through a process called plucking. These processes are used together to broaden, smoothen and deepen the U-shaped valley.

This can cause a small valley to ‘hang above the main one. This valley is often filled with ribbon lakes, that are formed by the rushing of water through the glacier. The valley is also marked by striations, ruts and striations on the sides and bottom, as in addition to moraines and till on the floor.

U-shaped valleys are found everywhere in the world. They are prevalent in mountainous areas, including the Andes, Alps, Caucasus, Himalaya and Rocky Mountains. In the United States, they are typically found in national parks. Examples include Glacier National Park and the Nant Ffrancon Valley in Wales. In certain instances these valleys extend to coastal locations and transform into Fjords. This is a natural phenomenon that occurs when the glacier melts. It can take thousands of years to form these valleys.

They are deep

They are created in valleys in rivers that were filled by glaciers during the ice age. Glaciers degrade the valley floor by plucking and abrasion and cause the valley to grow deeper and expand more evenly than a river would. These kinds of features are prevalent throughout the globe in mountainous areas including the Andes, Alps, Himalayas, Rocky Mountains, and New Zealand.

The erosion of a valley in the river can transform it into a u-shaped valley, deepening and enlarging it. The erosive power of the glacier can also cause smaller side valleys to be left hanging above the main valley, which is often characterized by waterfalls. These types of features are referred to as « hanging valleys » due to the fact that they are hung over the main valley, as the glacier recedes.

These valleys are often enclosed by forests and contain lakes. Some valleys are dry and are used for farming, whereas others are flooded and may be explored as part of a kayaking or hiking excursion. Many of these valleys are in Alaska which is where glacial melt is at its most intense.

Valley glaciers are huge flowing ice like rivers that slowly creep down mountain slopes during a glaciation. They can reach depths over 1000 feet, and are the predominant form in the alpine regions of valley erosion. They eat away at the rock on the bottom of a valley and leave the valley with holes or depressions that are then filled with water. The lakes that result are wide and long and can be located on the peaks of certain mountains.

Another type of valley, a glacial trough is a U-shaped valley that extends into saltwater and forms an fjord. These are typical in Norway, where they are known as fjords. However, they are also found in other regions of the world. These are formed by melting the ice and can be found on maps around the globe. They are usually characterized by rounded sides that resemble an U shape in cross-section as well as steep sides. The walls of the troughs are generally made of granite.

The slopes are steep
