The second largest desert in the world, if all the sand was hollowed out, what would be underneath the desert?

Deserts do not exist innately. Many deserts were once oceans before they were formed, and there was a lot of sediment in the ocean. When the terrain of the desert was lower than other places, the seawater flowed through the mud carried here. The sand will settle. Over time, more and more sediment will accumulate, slowly forming a desert.

What kind of world is there under the yellow sand of the desert?

The bottom of the desert is mostly rocks, and some deserts are salt flats with no vegetation at all. There are sometimes valuable mineral deposits in the desert, and many oil reserves, gas and other resources have also been discovered in modern times. However, due to the relatively backward economy and scarce water resources in desert areas, many oil fields have not been effectively exploited.

For example, the Sahara Desert was not like this tens of thousands of years ago. It was a paradise of life with widespread oases. The Taklimakan Desert was not a desert more than 1 million years ago, but an oasis with flourishing plants, numerous lakes, and a humid climate. Nowadays, many rock paintings left by ancient humans can be found in the Sahara Desert, which contain a large number of animal remains. ; Mainly because the earth's plates are in constant motion. In the past, the environment here was suitable for plant growth, so there are many remains of animals and plants.

There are also rich resources under the desert

There is a lithosphere at the bottom of the desert. The sand in the desert is very fine particles, so if we dig away the sand on the surface of the desert , we will see a very ordinary bedrock layer, which is simply stone. If you dig down, you will see some slightly larger gravels. The stones will get bigger as you go down. If you keep digging, you will see the bedrock layer of the earth.

In addition to these stones, there is also an ancient city under the desert. On the ancient Silk Road, there were many cities and kingdoms in the desert areas, and there were many ancient tombs at the bottom of the desert. Although the ancients chose to be buried in Feng Shui treasures after their death, some people also chose to be buried in the desert, and finally under some deserts. There may be mineral resources such as oil.

What scientists have confirmed is that there is a crust under the desert

First of all, the first point is that scientists have verified and discovered through actual verification that there is a crust under the desert. The earth's crust is an important material that covers the entire earth's surface. And this material is also a very strong one that keeps the earth able to maintain deserts. Deserts are also an important material that blocks the earth's crust, so underneath the desert is the earth's crust.

Secondly, another point is that I personally estimate that there may be some soil under the desert. This soil may be a native product of these desert areas, but these deserts may be due to subsequent desertification or wind blowing. Some products brought. Therefore, it is extremely difficult for many plants to live in this area after covering these soils. After all, this tight desert directly hinders the survival of plants on it.

Can the Sahara Desert be wiped out?

In fact, the desert is also a natural landscape, and it will exist even without humans. There is no need for us to fight against nature. Perhaps in millions of years, as the plates move, the area we are now in may become a desert, and the desert may become an oasis.

But this does not mean that we are letting the desert go unchecked. We must control the sandstorms and soil desertification caused by the desert.
