What is Yardang in Geography ? What does Yardang mean ? How is a Yardang formed ? What are the external forces that are effective in the formation of Yardang? Is Yardang a form of wind etching?
Geographic formations called Yardang are quite common in Central Asia.
Non-hard and easily abraded stones such as clay, marl and sandstone are effective in the formation of Yardang. Yardang is formed by wind erosion. Examples are most common in the Central Asia region in the world.
Rough, recessed, grooved surfaces formed by resistant rocks are called Yardang. Yardang is formed by the abrasion and transportation of loose materials such as clay, marl, sandstone on the slopes by the winds.
Yardang is a geographical term used to refer to the hills running parallel to the wind direction. It is a form of wind etching. Winds, one of the external forces, are effective in its formation.
Yardangs are seen in deserts, in areas dominated by arid and semi-arid climatic conditions. In places where Yardang is seen, vegetation is quite undersized.
It is a form of wind erosion that is generally seen in arid climatic areas and its shape may vary according to the region. It occurs as a result of sweeping non-hard stones such as sandstone.
Yardangs are hill formations that can be seen in many parts of the world. The main factor affecting the formation of Yardang is winds. The fact that the materials swept by the wind is loose is the second important factor in its formation. Geography dictionary is the main source you can refer to for information about Yardang.
U-profile grooves are formed in parallel with the wind direction as a result of worn parts of the sedimentary rocks by wind. These grooves are called Yardang.
In places where Yardang is seen, there are many hardness differences between the layers. While soft layers wear very easily, hard layers do not wear easily. This landform appears in deserts.
Yardang is seen in the deserts of Central Asia, in the Uighur Autonomous Region, in the Western Desert in Egypt, in Turkestan.
Yardang occurs after sandstorms. But this process of formation is a relatively long process. Yardang can reach up to 6 meters in height.
The Swedish explorer Sven Hedin first used the word Yardang as a geographical term. Yardang is essentially a Turkish word.
If the wind blows constantly from the same direction in one place, it may cause the formation of giant channels. These giant channels are in the form of steep stacks and are called Yardang.
Yardang is Turkish world which means a sharp irregular ridge of compact sand lying in the direction of the prevailing wind in exposed desert regions, formed by the wind erosion of adjacent material that is less resistant.
Yardang is a streamlined protuberance carved from bedrock by wind abrasion by dust and sand, and the deflation process.
The term Yardang originates from the Turkish language which means a steep bank, and it was Sven Ander Hedin, a Swedish explorer who introduced it to the English language in 1903.
Yardangs are found in the deserts, and the largest concentrations of mega-yardangs are found in Sahara Desert near the Tibesti Mountains. There are other notable Yardangs in Phoenix Arizona at the Papago Park, which is a rock formation with a hole. There is another Yardang in Arizona near the town of Window Rock. This Yardang is made up of a 60 meter sandstone with a large hole in the middle. Geologists have also suggested that the Great Sphinx of Egypt was a Yardang.
Yardang is a streamlined hill carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion, dust and sand, and deflation.
