How deep is the Sahara Desert about? What s hidden under the sand?

The Sahara Desert is about a few hundred meters deep, and there are many rich water resources hidden under the sand, as well as oil and other resources.

Approximately 320 meters deep. Abundant groundwater resources and animal fossils. cultural relics and much more.

According to research, the reach from the top of the desert to the rock can reach about 320 meters, and under the sand of the desert, there is nothing special except that the sand is rock.

This is too many to count, covering an area of about 9.32 million square kilometers, located in northern Africa. The climatic conditions of the region are very harsh, and it is one of the most inhospitable places on earth for living things.

During the last ice age, the Sahara was not yet a desert, the climate was similar to that of East Africa, and about 30,000 ancient petroglyphs were found in the desert area, about half of which were in the N'Ajar plateau in southern Algeria, depicting river animals, such as crocodiles.

Prehistoric period. The prehistoric period is around the time of the Pleistocene. The Sahara was not very dry, but a vast alluvial plain of rivers. No signs of human activity were found at this stage, hence the name prehistoric, and there were rock art images in North Africa at that time.

The buffalo period lasted from about 10,000 years ago to about 8000 BC. Its petroglyphs are mainly found in southeastern Algeria, Chad and Libya. They were painted between about 10,000 BC and 8000 BC, rhinoceros.

The figures often wear round helmets, use clubs, axes, bows and arrows, and throw sticks to strike their prey, but no javelins are seen.

Let the sand density be 1450 kg m, the area of the Sahara Desert is 9.06 million square kilometers, the height is 320 m, and the side length is 9518 km, using the formula equal to m than v, v=20836234520000000000km, there are about 2 10 grains, that is, 2 billion trillion trillion grains.

Answer: If the sand density is 1450 kg m and the area of the Sahara Desert is 9.06 million square kilometers, the height is 320 meters, and the side length is 9518 km, using the formula equal to m ratio v, v = 20836234520000000000km, there are about 2 10 grains, which is 2 billion trillion grains.

It's too painful to ask.

There is as much sand in the Sahara Desert as there are stars in the sky Do you say yes?? Hehe.

Sahara.

ofThe average thickness is meters, but in the heart of the desert a little thicker, probablyThere will be several meters thick, in fact, underneath the sandIt's also land, of course, possiblyAnd oil andMineral ResourcesThose.

The Sahara Desert isThe largest sandy desert

The area of the area is about 9.32 million square kilometers.

It is not a place suitable for living things, the climate here is very harsh, and it is also the largest sandy desert in the world. The average thickness of the long-term accumulation is up to meters, of course, the center may be far more than meters, after all, after the wind and rain, it will only accumulate thicker and thicker. In fact, they are all curious about what is under the desert, as far as my personal opinion is concerned, it may also be the land, after all, it is the most primitive product on the earth, but there are also mineral resources, and you can only know by digging it out.

Sahara DesertMineral resources are abundantFinish.

With the development of the desert, people have gradually lived around the desert, and the mineral resources of the desert are very rich. It also facilitates neighboring countries, Libya and Algeria in North Africa.

At present, it has become the world's oil producer, which is the indelible achievement of the Sahara Desert, although the value of the desert is very slow, but such value is incomparable, once the resources are found, the value is endless! Now roads have been slowly built around the desert, making it easier for cars to enter.

Conditions for the formation of deserts

The first condition for the formation of a desert is the lack of water, no precipitation, coupled with long-term windy and sandy weather, the desert is slowly formed. The desert is also a major feature, that is, this kind of area is very hot, because there is no rain for a long time, the temperature is also very high, there is no living organism to survive, and it is also very heat-resistant and dry-resistant vegetation that can live, which is very small, after all, soil erosion, plants have less basic survival.

In fact, now that science is becoming more and more developed, I still hope that there will be fewer and fewer desert areas, after all, there will be no wind and dust storms without deserts. Of course, I hope that the public will take care of plants, only in this way can soil erosion be reduced.

Perhaps over time, it is possible for the Sahara to return to oasis status, and we are very much looking forward to the day when it is far away, but there is hope.

It's particularly thick, and it's changing, because the sand is flowing. New rocks may form underneath the sand due to their weight.

The Sahara Desert is particularly thick, and the average thickness is in meters, which is higher than the average one-story building. If it is in the middle of the desert, it can be several stories high. The sand of the Sahara Desert is rocks and mud, but there are also a lot of mineral resources.

It's very thick, it's thousands of meters deep, and there are some huge minerals hidden underneath, and these things are not allowed to be developed now, so most people don't dare to take them, even if they know that the things down there are very good.

The sand of the Sahara Desert is very thick and has reached a depth of 10 meters. There may be some ancient tombs hidden under the sand.

This statement is quite interesting. Harnessing deserts is a common aspiration of mankind. I think the desert can be governed, but not forested, but grassland.

In order to turn the desert into a grassland, it is a direction that can be worked on to prevent sandstorms to the greatest extent without damaging the natural environment. To achieve grasslandization, it is necessary to artificially change the natural phenomenon that the evaporation of the desert is greater than the amount of rainfall, to collect as much rainwater as possible, to use the groundwater in the desert without or in a planned way, and to develop a new technology that can irrigate more areas of grassland with the least amount of water, so that the desert can hopefully be managed.

And I'm working on this technology.

The desert is very thick, and the desert is also very large, which has caused a lot of trouble to many animals, and there is still sand under the sand, and no one knows what is under the sand at present.

Beneath the sand of the Sahara Desert, scientists have found evidence of a prehistoric giant lake. The Nile was formed about 250,000 years ago when the Nile crossed a low channel near Wadi Tushka and flooded the Sahara East, creating a lake that covered more than 42,000 square miles at its peak.

Ted Maxwell, a geologist at the National Air and Space Museum, and colleagues recently discovered evidence of the lake while studying Egyptian radar data from the Space Shuttle's radar terrain mission. Geologists pieced together the outlines of an ancient giant lake using images of wind-blown sediments, sediments from tap water, and bedrock seen by radar beneath desert sand. Extreme drought in Egypt has improved radar's ability to see features clearly.

Buried passages can be detected up to 50 feet below the desert surface.

Using fossil fish found in deposits about 250 miles west of the Nile at an altitude of 810 feet as a marker of the lake's highest coastline, scientists estimate that the Nile once flooded Egypt's entire Kisebba-Tushka depression, creating a massive lake. Scientists determined that the location of the Paleolithic human settlements near the Egyptian Pillars and Tafavi was equivalent to a lake covering about 42,000 square miles, placing these settlements in desirable near-water areas.

The location and elevation of another set of archaeological sites near Bir Kiseiba, 93 miles west of the Nile, indicate that the lake is located at 623 feet above sea level, making it the second lowest level of the lake and covering about 18,600 square miles. Geologists also used the elevation of the Tushka River as a base water level to calculate the size of the second lake, through which water from the Nile once flowed into the desert.

The newly discovered lakes add to the evidence of numerous early and mid-Pleistocene lakes in North Africa that may have supported human migration patterns, the researchers said.
