What is so special about Sahara?

Location.

The Sahara Desert is the largest desert in the world outside of Antarctica, located in northern Africa from the Mediterranean Sea in the north to the Sudanese steppes in the south. It is located south of the Atlas Mountains and the Mediterranean Sea (about 35°N) and north of about 14°N (250 mm contours).

The Sahara Desert stretches from the Atlantic coast to the north, the Atlas Mountains and the Mediterranean Sea to the north, the Red Sea to the east, and the Sahel – a semi-desert and half-steppe transition zone – bordering the Sudan and the Niger River valley in the south.

The Sahara Desert is the largest desert in the world, covering almost all of northern Africa. The desert is about 4,800 kilometers (3,000 miles) long from east to west and between 1,300 kilometers (800 and 1,200 miles) from north to south, with a total area of about 9,320,000 kilometers.

It runs through the northern part of the African continent, with a length of 5,600 kilometers from east to west and a width of about 1,600 kilometers from north to south, accounting for about 32% of the total area of Africa.

Sahara Desert Soil:

The soils of the Sahara Desert are low in organic matter and are often inactive, although nitrogen-fixing bacteria are present in some areas. The soil in the depression is often salty. The soils on the edge of the desert contain a higher concentration of organic matter.

There are many types of arid landforms in the Sahara Desert. It consists of a stony desert (rocky desert), a gravel desert, and a desert. The rocky deserts are mostly found in the central and eastern Sahara in the higher terrain, and the Nubian desert east of the Nile is also mainly rocky deserts.

Gravel deserts are mostly found between rocky deserts and deserts, mainly distributed in the stony areas of the Libyan desert, the Atlas Mountains, the Kusi Mountains and other piedmont alluvial fan areas.

Deserts are the most extensive, with large areas everywhere except for a few higher mountains and plateaus. The famous ones are the Libyan Desert, the Raibyanai Desert, the Al Obari Desert, the Eastern Desert and the Western Great Desert of Algeria, the Shesh Desert, the Juf Desert, the Avana Desert, the Birma Desert, etc.

The larger area is called the "sand sea", and the sand sea is composed of complex and regular sand dunes of various sizes, with complex and diverse forms, including tall fixed dunes, low mobile dunes, and large areas of fixed and semi-fixed dunes.

Fixed sand dunes are mainly found in the southerly near the grassland and along the Atlantic coast. From Libya to the west to the west of Algeria is the Quicksand Zone. Shifting sand dunes are constantly moving downwind. In the Sahara Desert, a record of 9 metres of movement of mobile dunes has been observed.

In the process of "adventuring", I learned to think independently, judge independently, and learn to approach the truth. In this process, we learn not only the correct answer to this question, but also the valuable scientific spirit and important research process. It can be said that the benefit of Mr. Whiteson is that he has learned to be independent and not rely on full-faith books.

As Mencius said: It is better to believe in the book than to have no bookSo, Mr. Whitson was the mentor who taught us the spirit of independent inquiry.

It's the Sahara. The largest desert in the world.
