Why are some rocks in the desert like mushrooms

The desert is a very magical zone, in the desert there is no grass, but there will be an oasis, in the desert, you often see a lot of strange stones, most of the stone shapes are very similar to mushrooms, it looks really cute, so what is the main formation of stone mushrooms in the desert?

In the place where the wind and sand are strong, if the horizontal joints and bedding of the exposed rock are very developed, it is easy to be eroded by the wind into a peculiar shape, especially if the lower lithology of an isolated protruding rock is soft, after long-term differential erosion, it may form a mushroom shape with a top larger than the bottom, which is called a wind erosion mushroom.

Wind erosion mushrooms are first formed from wind erosion columns. The wind erosion column is mainly developed in the bedrock area with vertical joints, and after long-term wind erosion, it forms isolated columnar rocks, so it is called wind erosion column. It can stand alone or in groups.

The abrasion is strong due to the high amount of sand in the air flow near the surface. If coupled with the difference in the lithology of the bedrock, the wind erosion column is often eroded into a rock with a large top and a small base, which resembles a mushroom, which is called a wind erosion mushroom.

Wind erosion mushrooms are generally an epiphytic form of wind erosion castles and other landforms developed in bedrock areas. It is easily distributed in the Yadan landform. Yadan landform is a wind erosion landform, refers to the wind erosion, abrasion of the surface of the surface of the formation of the shape, mainly wind erosion and rain erosion, the surface due to tens of millions of years of wind and sun, so that the surface of the flat sandstone layer to form wind erosion wall wall, wind erosion mushroom, wind erosion column, wind erosion ridge groove and wind erosion depression, residual mound, castle and other landform forms, Yadan landform to the wind erosion landform near Lop Nur Yadan area is the most typical and named.

The Yadan landform or wind-eroded mushrooms are very strange in the eyes of ordinary people, but they are common in the eyes of geologists - they are just the result of hundreds of millions of years of geological evolution.

Some of the rocks in the desert have very strange shapes, and from a distance, they look like large mushrooms standing one after another. The formation of these mushroom-shaped rocks is closely related to the high winds in the desert. There are fewer obstacles in the desert, so there are often strong winds, and the heavier sand grains are difficult to be blown very high by the wind, and can only be swept not far above the ground, so when the wind blows with the sand grains, the lower part of the rock is more abrasive after the friction of the wind with a large number of sand grains, while the upper part of the rock, because the sand particles brought by the wind are relatively small, the abrasion is not too serious.

Over time, the rock becomes coarse at the top and small at the bottom.

Rock bucket reedite, is a solid mineral or a mixture of minerals, rocks under the surface of the sea, called reefs, reefs and sand. It is a collection of one or more minerals, with a certain structure and structure, and a few containing the remains or remains of living beings (i.e., fossils). Rocks are classified according to their genesis, structure, and chemical composition, and are mainly divided into three categories:

Sedimentary rocks, magmatic reefs (also known as igneous rocks), metamorphic rocks. Its material composition, structure, structure, classification and naming, formation conditions, distribution law, genesis, metallogenic relationship and rock evolution process have become the main content of geologists' research and an important basic discipline in geological science. Petrological hollows have become an important part of geological science in the desert.

It turns out that some rocks in the desert have strange shapes, and they look like three-dimensional mushrooms from a distance. The formation of these mushroom-shaped rocks is closely related to the high winds in the desert. There are relatively few wind-blocking materials in the desert, and the north wind tends to blow very high, and the coarse sand grains are difficult to be blown very high by the north wind, and can only be scratched at a great distance.

Therefore, when the wind blows through the lower part of the rock, a large amount of wind brings the friction of the sand particles, and the friction of the wind and sand is relatively large, and the corrosion is not very serious. On the top of the rock, because the wind blows less sand grains, the corrosion is not very serious. For a long time, the rock becomes coarse at the top and small mushroom-like at the bottom.

Stone mushrooms in the desert are mainly formed by wind erosion.

Wind erosion Wind entrainment of sand and gravel hitting the bottom of the stone, is the bottom of the continuous smaller, the formation of large at the top and small at the bottom.

Weathering, the temperature difference in the desert area is larger, and the rainfall is less, the weather is mainly sunny, the temperature difference between day and night will make the rock change physically, a cold and a shrinkage will change the spacing between the rock molecules, so that the rock slowly cracks, coupled with the wind generated by the temperature difference between day and night, the wind is mixed with fine sand, which will make the bottom of the rock wear a little bit, and over time it will form a mushroom stone.

Stone mushrooms in deserts are mainly formed by wind erosion.

In places where the wind and sand are strong, if the horizontal joints and bedding of the rocks on the surface of the exposed ground are very developed, they are easy to be eroded by the wind into a peculiar shape. In particular, if the lower part of the rock is softer and the lower part is eroded, it may form a mushroom shape with a larger top than the bottom, which is called a mushroom rock.

Mushroom rocks mostly occur in layered rocks, and during weathering, the rocks collapse, forming isolated columnar rock masses. On this basis, after the polishing and carving of the sand, the mushroom rock is gradually formed. The reason why it can form a mushroom shape that is large at the top and small at the bottom is not only related to the difference in the softness and hardness of each layer of the rock, but also directly related to the height of the wind and sand flow.

Read well. Because it was blown by the wind, and struck by sand and stones. This is what it looks like.

In the place where the wind and sand are strong, if the horizontal joints and bedding of the rock on the surface of the ground are very developed, it is easy to be eroded by the wind into a peculiar shape, especially an isolated protruding rock, if the lower lithology is soft, after long-term erosion, it may form a mushroom shape with the top larger than the bottom, which is called mushroom rock.

In arid areas, the formation of many terrains, such as the formation of mushroom rocks, is similar to the erosion process of flowing water, and everyone has experienced wind-blown sandstorms, especially in the northern regions, this phenomenon is more common. In dry areas, due to the wind near the ground containing more sand grains, the abrasive force is stronger, so that the rock forms a mushroom-like shape with a large top and a small bottom, which is called"Wind erosion mushrooms".And the air flow containing a large number of sand grains, when the wind speed decreases, the sand particles are deposited to form sand dunes.

Sand dunes can bury villages, roads, pastures, and bring quicksand hazards.
