What kind of world is under the desert sand?
Most deserts are 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, natural gas and other resources have been discovered in modern times. However, many oil fields have not been effectively developed due to the backward economy and lack of water resources in desert areas.
For example, the Sahara desert was not like this tens of thousands of years ago, but an oasis of life. Taklimakan Desert was not a desert 1 10,000 years ago, but an oasis with lush plants, numerous lakes and humid climate. Nowadays, many rock paintings left by ancient humans can be found in the Sahara desert, which are all animal remains; Mainly because the earth plate is constantly moving, the environment here used to be suitable for plant growth, so there are many remains of animals and plants.
There are abundant resources under the desert.
There is a lithosphere at the bottom of the desert, and the sand in the desert is very fine particles, so if we dig out the sand on the surface of the desert, we will see a very common bedrock, which is simply a stone. If you dig down, you will see some slightly larger pebbles. The deeper you dig, the bigger the stone is. If you keep digging, you will see the bedrock of the earth.
Besides these stones, there are ancient cities under the desert. On the ancient Silk Road, there are also many cities and kingdoms in the desert, and there are many ancient tombs at the bottom of the desert. Although the ancients chose to be buried in the land of feng shui after their death, some people chose to be buried in the desert, which may contain mineral resources such as oil.
Scientists have confirmed that there will be crust under the desert.
First of all, the first point is that scientists have found through practice that there is a crust under the desert, which is an important material covering the whole surface. This material is also to enable the earth to maintain the desert, which is also a very powerful weight, and the desert is also an important material covering the earth's crust, so below the desert is the earth's crust.
Secondly, I personally estimate that there may be some soil under the desert, which may be the original product of these desert areas, but these deserts may be some products brought by desertification or wind. Therefore, from now on, it is extremely difficult to cover the soil and make many plants want to survive in this area. After all, this dense desert directly prevents plants from living on it.
Can the Sahara desert be destroyed?
In fact, the desert is also a natural landscape. Even without human beings, the desert will exist, and we don't need to fight against nature. Maybe millions of years later, with the movement of the plate, the area where we are now may also become a desert, and the desert will also become an oasis.
But it's not because we leave the desert alone. We should control sandstorms and soil desertification caused by deserts.
