Xinjiang Gobi desert
How is the Gobi formed
When the train to Xinjiang passes through the junction of Gansu Province and Xinjiang, it will pass through the Gobi Desert called "8-mile Gobi". Looking around, the endless gravel beach shines in the sunlight. Whenever a strong wind passes, yellow sand rolls and blocks the sun. The whole area is deserted and desolate.
So, how was the Gobi Desert formed? Scientists believe that over the past two million years, especially in the middle, late and Pleistocene periods since hundreds of thousands of years, the topography of western China has been rising and the dry climate zone has been expanding. Under the action of the sun and wind, loose rock masses such as sandstone, silty mudstone and glutenite deposited on the surface of these areas are constantly weathered and denuded into a large number of clastic materials.
these mixed-size debris disintegrated from the mountain and began to pile up at the foot of the mountain. Under the action of flood, it was washed to the distant foothills, forming a large area of alluvial plain.
During the dry season, the fine sand and dust in the clastic materials on the alluvial plain are blown into the sky under the action of strong winds, and the dust is blown to areas thousands of miles away, forming the Loess Plateau; And those fine sands are carried nearby by the wind, forming a desert. Gravel with relatively large particle size was left in place, forming the present Gobi desert landform.
Which city is the Gobi Desert in Xinjiang?
Gobi Desert is everywhere in Xinjiang.
the Gobi desert is a landform on the edge of the desert. It is mainly composed of gravel and coarse sand.
Its main characteristics are excellent permeability, lack of water on the surface and few plants. Only some drought-tolerant plants such as Tamarix and Alhagi grow, and it is often windy. The main reason for its formation is flood alluvial.
When there is a flood, especially in mountainous areas, due to the gradual weakening of the flood energy, the following landform features are formed in the flood-hit areas: large pieces of rocks are piled up at the nearest mountain pass, and the rocks gradually become smaller outside the mountain; Then came rocks the size of fists and fingers. Due to years of sun, rain and wind erosion, the edges and corners are gradually rounded and become what we call stones (scientific name is gravel).
in this way, the Gobi desert was formed. And those finer sand and mud are alluvial and float farther, forming a distant desert.

The gravels with relatively large particle size were left in place, forming the present Gobi desert landform. Poplar is the most common tree in northwest China, where there is grass, there is the shadow of poplar.
Poplar doesn't pay much attention to the living conditions. On the roadside and beside the ridge, as long as there is loess, she can survive. She doesn't chase after rain or lust for sunshine. As long as she can give a little water to the hardened land, a branch of poplar will take root and sprout.

The finer sand and mud are alluvial and float further, forming a big desert farther away.
how did the Gobi desert in Xinjiang come into being?
The formation of Taklimakan Desert is directly related to the uplift of Qinghai-Tibet Plateau.
8 million years ago, the Indian plate continued to drift northward, resulting in a strong tectonic movement-Himalayan movement. The uplift process of the Qinghai-Tibet Plateau has gone through several different stages. Every uplift makes the plateau landform evolve. Ten thousand years ago, the plateau rose faster, rising at an average annual rate of 7 cm, making it the "roof of the world" on the earth today.
The formation of the Qinghai-Tibet Plateau has greatly reduced the precipitation in southern Xinjiang and turned the climate into dryness. In winter, the westerly jet near the ground in China moves south, and its northern branch airflow will be weakened by the blocking force of the Qinghai-Tibet Plateau near the ground, making the climate in the vast areas of northern China cold and dry; In summer, because the southwest monsoon from the Indian Ocean rarely crosses the Qinghai-Tibet Plateau and enters the northwest of China, the climate in Gansu and Xinjiang will be dry. The continuous drought has made the Taklimakan area a vast desert today.
