"How deep is the desert in the Sahara?"
This is an interesting challenge, because the Sahara Desert is so vast that it is impossible to imagine the depth of the desert from a visual point of view.
However, such a desert is a hot land for human beings, which has experienced millions of years of vicissitudes, and there are not only classic desert landforms, but also rich desert history.
So, if we hollow out all the sand of the Sahara Desert, what will be left underneath?
1. The Sahara Desert.
The Sahara Desert is the largest desert in the world and the third largest desert in the world, after the Kobe Desert in the United States and the Mongolian Desert in Asia.
With an area of about 9.32 million square kilometers, the Sahara Desert covers almost the entire northwest of the North African continent except for the edge of the Atlantic Ocean.
The formation of the Sahara Desert can be traced back to 2.5 million years ago, which is very long, and the Sahara Desert has been evolving in these 2.5 million years.
The dunes and rivers that sustain the desert are rich in prehistoric water remains, and possibly even the remains of paleontology, all of which bear witness to the rich history of the Sahara Desert.
In ancient times, the area of the Sahara Desert was not as large as it is now, and this area was located at the junction of a green desert and an oasis zone, known as the "desert oasis ecotone".
In this area, there are not only vast deserts, but also some aquatic plants, and some places with a similar climate to oases, where some animals and plants have found suitable living environments.
However, since then, the size of the desert has been expanding, and the size of the oasis has been decreasing, and this change has long since made the Sahara Desert no longer the prosperous and rich land it once was.
On the contrary, it has become an endless desert, a dead land devoid of any life, and as a result, the climate here has become extremely harsh, with perennial high temperatures and dry temperatures, and almost no precipitation.
On the edge of the Sahara Desert, there are indeed some oasis, but compared to the Sahara Desert, they are just a grain of rice in a basket, but they are only vassals of the Sahara Desert.
Therefore, geographically, the Sahara Desert has long been a major part of the local terrain, which, like other desert landforms, is one of the most numerous terrains on the planet, and its cool environment has become a chasm that is difficult to cross.
Second, the deepest part.
So, how deep is the desert in the Sahara?
This is actually not a very easy question to answer, because the depth of the desert is so great that it is difficult to see the bottom of it from the ground.
In addition, the depth of the desert also has a great relationship with where we are, and there is no definite answer to this question until now.
Until now, there are still many people living in the Sahara Desert, and in order to live, they have to destroy the desert to find land to live on, so we can't get a definite answer from here.
However, while we don't know how deep the Sahara desert is, there are ways to get an approximate estimate of the Sahara desert.
Of all the deserts, the Sahara Desert is the deepest, which is indisputable, and not only the desert, but also the rivers that maintain the ecology of this desert are the longest, which is also a major feature of the Sahara Desert.
The desert of the Sahara Desert is generally tens of meters, or even hundreds of meters deep, which is indeed deep enough for a desert, but for the Sahara Desert, this is far from enough.
In the deepest part of the Sahara Desert, the depth of the desert can even reach hundreds of meters, or even thousands of meters, and this number has a lot to do with the geological structure of the area where it is located.
Beneath the desert of the Sahara Desert, there are hidden relics of ancient water systems in the oasis area, and in these ancient water system ruins, there may be many remains of ancient creatures, however, we cannot find these things by any means.
Therefore, the depth of the desert, this problem, has also become an unsolvable mystery, those ancient water system remains, and the remains of ancient creatures, have also become a rainbow in the desert, untouchable.
But isn't that a challenge?
Human beings have always lived in curiosity and a desire to explore, so the foot of the Sahara Desert has also become a challenge for countless explorers, but so far, no one has been able to reach the deepest part of the desert.
3. What is hidden under the desert?
Desert sand is a very ordinary thing for us, however, in fact, the sand of the Sahara Desert is very different from the sand we usually see.
Because the desert of the Sahara Desert is generally tens of meters, or even hundreds of meters deep, therefore, there will be many layers of sand, so there will be a big difference between the sand in the ground and the sand on the surface.
On the surface of the Sahara Desert, sand is generally composed of sand and some fine sand, and their biggest feature is that it is very loose and contains some other impurities, so it can be said that these sands are the most common sands.
However, if the desert is dug up, the sand under the desert will change a lot, and these sands will be divided into several different levels.
The first level is fine sand, which is very similar to the sand on the surface, so it can be said that they are all components of the desert, but the difference between them lies in the size of the grains of this sand.
Fine sand tends to be very small, which is the biggest difference between it and surface sand, however, this fine sand tends to be the top layer of the desert, so it is also called "surface fine sand".
Under the fine sand, there will be a layer of colored fine sand, this kind of sand, which is very similar to fine sand, but its particles will also be mixed with some larger minerals, so it will appear to have some color, this kind of sand, will generally be buried by the thickness of the desert.
In addition, there is a layer of coarse sand, which is different from fine sand and colored fine sand, and its particles tend to be larger, so it will also appear coarse.
Underneath the coarse sand, there is also a layer of gravel, which is often the lowest part of the desert, because the particles in the gravel tend to be relatively large, so it can also be very hard, which makes it impossible for people to dig it up.
In addition, there are some rare hard rocks, which tend to be buried under the desert and are untouchable to us, so we cannot study them.
epilogue
Deserts, one of the most challenging landscapes on Earth, not only have extremely harsh environments, but also countless unknowns.
At the foot of the Sahara Desert, there may be hidden relics of ancient civilizations, and perhaps precious fossils, which are one of the great charms of the Sahara Desert.
Therefore, we cannot fully excavate the sand of the Sahara Desert, which is a part of nature and allows us to feel the magic of nature.
The sands of the Sahara Desert may provide important clues about the history of human beings, as well as the evolution of living things, and so on, which we want to know.
However, the environment of the desert is very harsh for human beings, and it is also a big warning for us, that is, we should respect nature, protect the environment, and not let there be another Sahara Desert on the earth.
