What Are U Shaped Valleys A Ushaped Valley is an ancient geological formation with steep high sides as well as flat or rounded valley bottom These valleys are formed by glaciation They often contain lakes or rivers sandtraps along a golf course kettle lakes water hazards or other natural features Glacial erosion creates Ushaped valleys when rocks are removed from the sides and bottom of the valley These valleys can be found in mountainous regions around the world Glaciers are the primary reason for forming them 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 valleys are distinct from river valleys that are usually shaped in the shape of an X Although glacial erosion can happen anyplace however these valleys tend be more prevalent in mountainous regions They are so distinct that you can tell if the landscape was created by glaciers or by rivers The process of creating a U shape valley begins by forming a V shaped river valley As the glacier recedes it encroaches upon the Vshaped valley of the river and creates an Ushaped inverted form The ice also scrubbing the surface of the land causing high and straight 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 way As the glacier continues to degrade the landscape it also makes the valley bigger and deeper The glaciers ice is less abrasive than the rocks As the glacier moves through the valley it also causes abrasion to the rock surfaces This pulls weaker rocks away from valley walls through a process called plucking These processes combine to broaden deepen and smooth the Ushaped valley This process can cause small valleys to hang above the main one The valley may be filled with ribbon lakes which are formed when water rushes through the glacier The valley is also characterized with striations and ruts till on the sides as well as moraines and till on the floor Ushaped valleys can be found all over the world They are prevalent in mountainous areas including 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 valleys can extend to the coast and turn into Fjords This is a natural process that happens when the glacier melts and it can take many thousands of years for these valleys to be formed The oceans depths are deep Ushaped valleys are distinguished by steep sides that curve at the bottom and a wide flat valley floor They are created by river valleys that have been filled with glaciers during the Ice Age The glaciers erode the valleys floor by plucking and abrasion which cause the valley to deepen and expand more equally than a river would These features are found around the globe in mountainous regions including the Andes Alps Himalayas Rocky Mountains and New Zealand The erosion of glaciers in the valley could transform it into a Ushaped one by deepening and expanding it The force of the glaciers erosion can also cause smaller side valleys which are usually marked by waterfalls to rise above the main valley These are referred to as hanging valleys because they are hung above the main valley as the glacier recedes These valleys are usually covered by forests and can contain lakes Some valleys are used for farming while others are flooded Many of these valleys are located in Alaska in the region where glacial melt is the most evident Valley glaciers are massive flowing like rivers that slowly slide down mountain slopes They can reach depths of over 1000 feet and are the dominant form of valley erosion in alpine regions They eat away the rocks at the bottom of the valley causing depressions and holes filled with water The lakes that result are wide and long and can be found on the peaks of certain mountains A glacial trough is another type of valley It is a U shape valley that extends out into salt water to create the fjord They are all over the world including Norway which is where theyre known as fjords These are formed by melting ice and are visible on maps around the globe They are usually characterized by rounded sides that mimic the shape of a U shape in crosssection as well as steep sides The walls of troughs are typically made of granite They are sloping A U shape valley is a type of formation with high steep sides and a smooth bottom They are very frequent in mountainous regions and are usually formed by glaciers This is due to glaciers slow movement downhill and then scour the land Scientists once believed that glaciers could not create valleys because they were so soft But now we know that they are able to Glaciers form distinctive ushaped valleys through the processes of plucking as well as abrasion Through erosion these processes can widen steepen and deepen V shaped valleys of rivers The slopes of the valley bottom are also altered cool training take place in the front of the glacier as it is pushed into a valley This is the reason why the top of Ushaped valleys is usually wider than the bottom Ushaped valleys can 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 may be a temporary feature while the glacier melts or can remain when the glacier recedes These lakes are often located alongside cirques Another type of valley is one with a flat floor This valley is formed by streams that degrade the soil However it does not have a steep slope like a Ushaped one They are usually found in mountainous areas and can be older than other kinds of valleys There are many different types of valleys in the world and each has its own distinct appearance The most common is a Vshaped valley but there are other varieties including Ushaped valleys and rift valleys A rift valley develops in places where crust of the earth is breaking apart These are often narrow valleys with steep sides This is evident in the Nant Ffrancon Valley located in Snowdonia There are a variety of common Ushaped valleys are characterized by their broad bases unlike Vshaped ones They are usually found in mountains and are formed by glaciers Glaciers are huge blocks made of ice and snow that erode landscapes as they move downward They degrade valleys by crushing the rocks with friction and the abrasion This erosion is known as the scouring The glaciers degrade the landscape in a distinctive Ushaped pattern These valleys also referred to as Ushaped Valleys are able to be found in numerous locations across the globe The valleys are formed by glaciers that erode the valleys of rivers The glaciers slow movement and weight is able to erode the valleys sides and floor and creates a distinctive U shape This process also known as glacial erosive erosion has resulted in some of the most beautiful landscapes on Earth These valleys are sometimes referred to as glacial troughs or trough valleys They are found all over the globe but are particularly found in regions with glaciers and mountains They range in dimensions from a few meters to hundreds of kilometers They can also vary in length and depth The fluctuation in temperature will be higher the deeper the valley When a Ushaped valley is filled with water it develops into a ribbon lake or fjord The ribbon lakes develop in the depressions in which the glacier cut the less resistant rock They also can develop in valleys where the glacier was halted by a wall of moraine In addition to Ushaped valleys the ribbon lakes can also contain glacial features such as hanging valleys erratics and moraine dams Erratics also known as massive boulders are created by a glacier as it moves They are commonly used to mark the boundaries of glaciated regions These smaller valleys are left hanging above the main valley created by the glacier They are less icecovered and arent as deep They are carved by glaciers that tributary to the main valley and are usually covered by waterfalls
