What Are U Shaped Valleys A Ushaped valley is an geological formation with steep high sides and a flat or rounded valley bottom These valleys are formed by glaciation They often contain lakes rivers sandtraps on golf courses kettle lakes water hazards or other natural features Glacial erosion causes Ushaped valleys when rocks are ripped from the bottom and side of the valley These valleys are found in mountainous regions all over the globe They are created by glaciers Glaciers are huge bodies of ice that form and move down mountains As they degrade the landscape they create Ushaped valleys that have flat floors and steep sides These valleys are different from the valleys of rivers which are usually designed to look like the letter V While glacial erosion can occur in many places however these valleys are typical of mountain regions In fact they are so distinctive that you can tell if the landscape has been shaped by glaciers or by rivers The formation of a Ushaped valley starts with an existing Vshaped river valley As the glacier is eroding the landscape it encroaches on the Vshaped river valley and produces an inverted Ushaped The ice also scour the lands surface creating straight and high walls along the sides of the valley This process is called glaciation and it requires a great deal of strength to scour the earth in this way As the glacier continues to erode the landscape it also makes the valley deeper and wider The ice is less frictional than the rocks As the glacier moves down the valley it also causes friction on the rock surfaces and pulls the rocks that are weak away from the valley walls in a process referred to as plucking These processes are used together to widen smoothen and deepen the Ushaped valley This also causes small valleys to hang above the main one The valley may be filled with ribbon lakes that are formed when water flows through the glacier The valley is also marked with striations and ruts till on the sides as well as moraines and till on the floor The world is filled with Ushaped valleys They are prevalent in mountainous regions including the Andes Alps Caucasus Himalaya and Rocky Mountains In the United States they are typically found in national parks Examples include the Nant Ffrancon valley in Wales and Glacier National Park in Montana In some instances valleys can expand to the coast and turn 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 formed They are deep Ushaped valleys are distinguished by steep sides that curve at the bottom and a wide flat valley floor They are formed by river valleys that have been filled with glaciers during the Ice Age Glaciers erode the valley floor by abrasion and plucking which cause the valley to grow deeper and expand more evenly than a river would These features can be found in mountainous regions across the globe including the Andes Mountains Alps Mountains Himalayas Mountains Rocky Mountains and New Zealand The erosion of a valley in the river can transform it into a ushaped valley by increasing its depth and expanding it The erosive force of the glacier can also cause smaller side valleys to hang above the main valley which is often characterized by waterfalls These types of features are referred to as hanging valleys because they hang over the main valley when the glacier retreats These valleys could be covered in forest and may contain lakes Some valleys can be used for farming while others are flooded A large number of these valleys are in Alaska in the region where glacial melt is at its most intense Valley glaciers are massive like riverlike flows that slowly slide down the slopes of mountains They can extend to depths of over 1000 feet and are the dominant form in alpine areas of valley erosion They devour the rock on the bottom of the valley and leave the area with depressions or holes which are then filled with water The lakes that result are wide and long and can be located on the peaks of certain mountains Another kind of valley called a glacial trough is a Ushaped valley that extends into saltwater and creates a Fjord These are common in Norway in Norway where they are referred to as fjords but are also found in other parts of the world They are formed by melting glaciers and can be seen on maps of the world They are distinguished by their steep sides and round sides that form a Ushape u shaped sectional small of troughs are generally made of granite They are steep A U form valley is a geological formation with high steep sides and a smooth bottom They are frequent in mountainous regions and are usually carved by glaciers It is due to glaciers slow movement downhill and scour the land Scientists used to believe that glaciers couldnt carve valleys due to being so soft However now we know that they can Glaciers create distinctive ushaped valleys through the processes of abrasion and plucked Through erosion these processes may widen steepen and deepen V shape river valleys They also alter the slopes of the valley floor These changes take place in the front of the glacier as it moves into a valley This is the reason why the U shaped valley is often larger at the top than at the bottom U shaped valleys are sometimes filled with lakes These lakes are known as kettle lakes They form in hollows that were eroded out of the rock by the glacier or were dammed by the moraine The lake may be a temporary one as the glacier melts or it may remain after the glacier has receded They are often associated with cirques Another type of valley is a flatfloored valley This valley is formed by streams that degrade the soil However it does not have a steep slope as a Ushaped one They are usually found in mountainous areas and are often older than other types There are many different types of valleys around the world and each one has a unique appearance The most popular is a Vshaped valley however other forms include Ushaped valleys and rift valleys A rift valley is one that develops in places where crust of the earth is breaking apart They are usually narrow valleys with steep sides This is evident in the Nant Ffrancon Valley located in Snowdonia They are broad Ushaped valleys are distinguished by their broad bases unlike Vshaped ones They are most often found in mountain ranges and are shaped by glaciers Glaciers are massive blocks of snow and ice that alter landscapes as they move downwards They erode valleys through friction and abrasion This process is referred to as scouring The glaciers degrade the landscape in a distinctive Ushaped design These valleys often referred to as Ushaped valleys can be found in numerous locations across the globe The formation of these valleys occurs when glaciers erode existing valleys of rivers The glaciers slow movements and weight erodes the valleys floor and sides creating a distinct U shape This process known as glacial erosion has resulted in some of the most stunning landscapes on Earth These valleys can also be called trough valleys or glacial troughs They are found all over the globe and are especially found in regions that have glaciers and mountains They can range in size from a few meters to several hundred kilometers They can also vary in depth and length The deeper the valley the larger the fluctuation of temperature will be A fjord or a ribbon lake is formed when a Ushaped valley is filled with water The ribbon lakes develop in depressions where glaciers cut away less resistant rock They can also form in valleys in which the glacier is stopped by walls Ushaped valleys could also include other glacial features like moraine dams hanging valleys and erratics Erratics which are massive boulders are created by glaciers as it moves The erratics are often used to mark the boundaries of glaciated regions Hanging valleys are smaller side valleys that are hanging above the main valley that was created by the glacier They are less icecovered and arent as deep They are carved by tributary glaciers and are usually overshadowed by waterfalls
