The Sahara Desert is one of the most typical desert landscapes. When talking about Africa, the first thing everyone thinks of is the endless desert landscape. So what is the height of the top of the desert to the ground? If the sand in the area is transferred to other positions, will the Sahara Desert show the most primitive landform? You may not think of it. Today we will solve these puzzles and take you into the most authentic Sahara Desert.
The Sahara Desert was formed in about 2.5 million years ago. It was the second largest desert in the world after Antarctica. The Sahara Desert was also the world's largest sandy desert. It is located in northern Africa and has a very harsh climate conditions in the region and is one of the most unsuitable places on the earth. Its total area can accommodate the entire United States.
On our planet, there are a variety of ocean flows. In the western coast of North Africa, there is just an ocean current, which is Ganary cold current. The cold current allows the western region to cool down and reduce dampness, so that the Sahara desert can approach the west coast.In addition,northern Africa is located on both sides of the Regression line, and is controlled by the subtropical high pressure all year round. Due to the impact of air flow, the range of air pressure bands has gradually increased, so it has formed such a huge drought area.
At the same time, northern Africa is adjacent to Asia. Therefore, the region is affected by the trade wind, which is not only difficult to form rainfall, but also makes the climate in northern Africa get more dry. Northern Africa has the Ethiopian Plateau, which can effectively prevent the circulation of air flow, which in turn causes the lack of humid airflow in the desert area. What's more, the terrain in northern Africa is relatively simple, and it is easy to form a desert area.
Different desert coverage of regional terrain can lead to different yellow sand coverage. According to data research, the sand on the surface of the Sahara Desert is as high as 320 meters from the real ground, and the average height is 150 meters. However, the sand in the Sahara desert is liquid, and the wind will flow as soon as the wind shakes. So even if people come to the same place for the second time, different desert heights will appear. Such a big and so high desert, it is difficult to imagine how many monuments buried underneath.
If all the sand in the Sahara Desert is moved to other areas, it will show out of the land that is not deserted. This land is full of desolation. We can't see any plants, nor can we feel the vitality and hope of this land. If people living in the desert can grow green trees in the desert area, the desert will become an oasis.
The Sahara desert climate is hot and dry. However, it is confusing that in this extreme drought and water -deficient mineral land, there have been prosperous ancient civilizations. Many large and beautiful murals on the desert are the crystallization of this ancient civilization.
Although the Sahara desert area is large, its residents are estimated to be only 2.5 million, and less than 0.4 people per square kilometer. The large area is empty, but as long as the thin and barren vegetation can support livestock, or with reliable water sources, the scattered people will survive in the most difficult environment in this world and the precarious ecological environment.
