Sahara Desert facts for 2020

Shahara desert facts

The title of the world's warmest desert is occupied by the Sahara Desert in Africa. But the Sahara is not the largest desert in the world. The largest desert in the world is Antarctica. It is the third largest desert in the world in terms of size. Generally, an area with low annual rainfall is called a desert. The Sahara Desert was a lush green forest about 20,000 years ago.

The Sahara Desert, which covers about one-third of the African continent, is 4,600 km long from east to west. And in the north-south it is 1,600 kilometers or 1,100 kilometers wide. In all, the Sahara Desert is 92 million square kilometers or 36 million square miles. Which is equal to the size of the United States or China. Geographically, the Sahara Desert is bounded on the north by the Mediterranean Sea, on the east by the Red Sea, and on the Atlantic Ocean. The Niger River flows south of the desert. Judging by the political boundaries, 10 countries are currently controlling the Sahara Desert. The countries are Algeria, Moon, Mali, Egypt, Libya, Sudan, Mauritania, Niger etc. The sand of this desert can reach a height of about 200 meters or about 650 feet. This means that they can be as tall as a 75-storey building. For the Bedouins, crossing the Ballard as a means of transportation to this desert has become a daily task. However, for the unaccustomed, the issue can be fatal. The sands of this desert float in the air and cross the Atlantic Ocean regularly. The sands of the Sahara Desert serve as fertilizer for the trees of the Amazon rainforest, located only in South America. The Sahara Desert may seem sandy, but the reality is startling. According to geologists, the Sahara Desert is made up of only 30 percent sand. The remaining 80 percent is made of stone. The east-west areas of the desert can be called hilly.

In prehistoric times this Sahara desert was once submerged under a huge sea for millions of years. The highest point of the desert is the Amiga volcano, which forms part of the Tides ti Mountains on the northern tip of the country now known as the Moon. At an altitude of 3,415 meters or about three and a half kilometers above sea level, the volcano has multiple hot springs at its base. They have a water temperature of about 36 degrees Celsius. Which is very comfortable for bathing.

Everyone knows that the temperature in this desert is much higher. However, the difference between the atmospheric temperature and the surface temperature of this region is shocking. The average temperature in the Sahara is about 36 to 40 degrees Celsius. The official maximum temperature is 48 degrees Celsius. It is simply the temperature of the atmosphere. But the surface temperature sometimes exceeds 60 degrees Celsius. At night the temperature in the Sahara Desert can drop to 13 to 20 degrees Celsius. Many countries are gradually becoming interested in using this temperature in the Sahara Desert to generate solar power. The Sahara Desert is capable of generating about 3,000 kilowatts of electricity per square kilometer per year.

Although this desert is unsuitable for human habitation, many animals live here. The most eye-catching animal to cross this desert is the camel. Most of these are wild. Other notable animals include foxes, chameleons and deer in the Share desert. There is also a species of cheetah called Sahara Cheetah that lives in this desert.

The flora of the Sahara Desert is no less diverse. According to scientists, about 3,000 species of plants, including cactus, live in this desert.

Surprisingly, this desert was a grassland forest surrounded by greenery only 20,000 years ago. 15,000 years from now, that is, by 18,000 years, this desert will again take the form of grassland. According to scientists, the earth tilts 23.4 degrees as it orbits the sun. But this tilt changes every 41,000 years. This led to a huge change in the seasons of the whole of North Africa. As a result, the rainfall in the Sahara region increased several times. That is why the Sahara Desert was once a grassland. There are about 24 lakes in different parts of the Sahara Desert. However, except for one, almost everything is saline. One reason is that the desert was once under the sea. Also found here are parts of huge creatures, which confirms that this desert was actually under the sea.

Just as biologists have discovered a variety of biodiversity in the heart of the Sahara Desert, archaeologists have not returned to the desert empty-handed. Here they found a 6,000-year-old circular installation. These man-made structures were used in the religious rituals of different tribes. There are also a variety of imagery to be found in this area. Fossils of prehistoric animals have also been found here. The number of dinosaur fossils is not less. Last year, scientists also recovered 80 million-year-old dinosaur fossils from here.
