What Scientists Just Uncovered Under The Sahara Desert SHOCKS The Entire World!

Endless sand landscapes, scorching sun and total absence of people around, this is how one of the most famous

desert

s in the

world

, the Sahara, is drawn in the imagination, it seems that the golden dunes have always been here, but when you look it is not like that. . In the Sahara there are infinite sands and silent dunes. You want to know

what

is underneath millions of tons of sand. In this issue, I promise to take a trip to the past and discover if this part of the African continent has always been an arid and lifeless

desert

. hides under the sands of the Sahara, let's find out that the name Sahara comes from a common Arabic word that in translation simply means desert, contrary to popular belief, the Sahara desert is not the largest on Earth, the Antarctic desert has primacy , but among the usual deserts with heat of sand and dunes, the Sahara is actually the largest.

The desert covers almost a third of the

entire

African continent and covers more than 8.5 million square kilometers of land area. The Sahara extends for 10 African countries and is surrounded by the Atlantic Ocean, the Red Sea and the Mediterranean Sea. With each passing year, the desert expands relentlessly towards the south, claiming an additional 5 to 10 kilometers annually, while the common perception of the Sahara is the of towering sand dunes, cacti and a lack of flora and fauna, actually only 20 percent. of its terrain is covered with sand the predominant landscape is made up of rocky plateaus although this region is not really rich in animals there are still around 4,000 species among which are mammals gerbils gerbils antelopes jackals dune cats and mongooses most of these Inhabitants are nocturnal and during the day they hide in shelters from the scorching sun.

This is because the desert temperature regime is prone to large fluctuations. During the day the average air temperature reaches 35 degrees, but the sun heats the sand more than twice as much, creating a feeling of being in a hellish frying pan. The Sahara Desert is a dry and hot climate with rare precipitation that averages only 75 millimeters of rain per year the highest temperature recorded is almost 58 degrees while the temperature at night quickly drops to almost zero degrees with frost On the mountain plateaus with temperatures as low as -18 degrees despite the harsh climate, The desert is home to a variety of flora including more than 30 species of endemic plants, such as Fern Ficus Acacia cacti and date palms.

Temperature changes have a destructive effect on rocks, causing them to crack and gradually turn into sand which replenishes the desert sand layer. Sand dunes in the Sahara can reach up to 200 meters and some dunes produce sounds that merge into a strange melody due to grains of sand oscillating under the influence of the wind in unusual areas of the Sahara also contain transparent pieces of weathered glass which are believed to have formed from meteorite impacts millions of years ago. Mirages are another fascinating feature of the Sahara, while the only river that flows across the desert borders is the Nile, although rainfall is scarce, there are permanent lakes such as the Aeonianga. group of lakes in the Sahara despite the harsh climate the Sahara is rich in unique geological and biological features that continue to fascinate

scientists

and explorers alike how many people traveling through the desert have suddenly seen oases with water and palm trees thinking they are approximately two or three kilometers from them, in fact, sometimes it is necessary to walk 500 kilometers or more to the nearest water a mirage is an optical phenomenon in the atmosphere a refraction of the flow of light occurs at the boundary between layers of air that They differ in density and temperature.

In the Sahara, more than 150,000 mirages are observed. Maps have even been created of the places where they can be seen. The difference with reality is that along with a truly visible image of an object, its reflection in the atmosphere is visible, the main The wonder of the Sahara and one of the main mysteries of the planet is located in Mauritania and is called rigid structure. It is an annular structure with a diameter of 50 kilometers and dating back several hundred million years for a long time, the eye of the desert. It served as a landmark for the astronauts because it is perfectly visible from orbit and is the only obvious landmark in the vast expanse of a nondescript desert.

There are several hypotheses explaining this phenomenon, according to one of which the appearance of a ring structure is the result. of erosion the highest point of the Sahara is the Emikusi peak which rises three kilometers 400 meters above sea level Rich deposits of gas and oil have been discovered in the territory of the Sahara desert under the influence of the winds of the monstrous sand storms are born in the south, which then hit neighboring countries and sometimes rage for several days. For example, every year strong winds knock down clouds full of sand raised in the Sahara in the African island country of Cape Verde, creating a lot of inconvenience for residents. despite the harsh conditions in which around 2 million people live. in the Sahara mainly Berbers and two are eggs in medieval times trade caravans traveled through the desert, the largest of which, according to Arab historians, was made up of almost 12,000 camels to discover the most important secrets, we must delve deeper In the very heart of this desert there is a treasure of the Sahara beneath many dunes there is very little water on the surface of the desert due to the lack of rainfall but under the sands of the Sahara there are vast pools of underground water it is thanks to these pools that Oasis In the Sahara, areas rich in vegetation can be found.

Most of the oases here arise in places where water from underwater rivers comes to the surface. Some countries located on the territory of the Sahara groundwater are dedicated to the extraction of this value. invaluable The most fertile liquid in this sense is the northeastern part of the desert, where Sudan, Chad, Egypt and Libya are located. The aquifer in Libya is the largest. Groundwater has been extracted here since the 1970s and in 1983 work began on a huge project with the aim of supplying drinking water to the dehydrated settlements of Libya, in 1996 regular water supply was established for all cities. important in the country.

This great system called the Great Artificial River supplies six and a half million cubic meters of drinking water. Every day in 2008 it was entered in the Guinness Book of Records, recognizing it as the largest irrigation project. The great artificial river consists of 1,300 wells more than 500 meters deep as well as numerous water pipes and reservoirs. All this would be impossible without the presence. of an aquifer under the Sahara Sands, it should be noted that this desert is much more generous with its inhabitants than it might seem at first glance, but in reality the Sahara has not always been as we know it today, it is difficult to believe.

But about 8,000 years ago in the place of the Sahara there was a green forest with lush vegetation, white grass, meadows and clear lakes. The Sahara has its own Stonehenge, called naptiplaya. This structure consists of two three-meter stones weighing several tons aligned in circles. At five rows, Nap di Playa is older than Stonehenge by more than four and a half thousand years, making it one of the oldest archaeological sites in history in the central Sahara. Archaeologists have discovered ancient rock carvings that indicate that primitive people lived during these times. Parts probably in these places there were many settlements of people who cultivated the land and raised livestock there was also a huge river Taman rasad that flowed into the Atlantic Ocean was discovered in 2015 using three-dimensional satellite images they also found the edges of Lake Chad, which in ancient times It was much wider and deeper than now and, according to experts, it was considered the largest on the planet.

Within 10 to 12 years people will have the opportunity to see the Sahara green again. Scientists have different assumptions about why the region turned green. In an arid desert, some blame the cattle that absorbed such a large amount of plants that they did not have time to grow and reflect the sunlight and therefore the sun began to burn the earth and the remaining vegetation. Others, on the contrary, claim that grazing and distillation have extended the life of the Sahara for 500 years and others are sure that the culprit is the Earth's axis, which changes its tilt every twenty thousand years.

Its displacement affects the intensity of sunlight. The history of the Sahara dates back to the Mesozoic Era when it was an ocean called thethis. teeming with giant ancestors of whales, snakes, turtles and dinosaurs, the breakup of the continent caused the oceans to disappear and now fossilized remains of these ancient creatures, including one of the
