The majority of North Africa is desert, with the exception of the Nile Valley in Egypt and the Sudan. Deserts give way to low-lying coastal lowlands in the eastern and northern Mediterranean regions, which runs from the Red Sea to the Atlantic. The Sahel region of Africa is a semi Arid tropical savana that borders the Niger River basin and Sudan in the south-eastern part of the continent. Sahara, the ahaggar mountaines, & tibesti and Ar mountains, the Ténéré Desert, and Libyan deserts are all included in this region.

By moving the North African monsoon, the Sahara has been changing from desert to savannaa grasslands in a twenty thousand year cycle.

Every country bordering the Sahara is in the Middle East or North Africa. Both Mali and Morocco are located in Mauritania. Approximately 31% of Africa’s geographical surface was covered by it as of two thousand and ten. More than 11 million square kilometres of the Sahara could be found if all regions with an annual rainfall of less than two hundred fifhty mm were included (42 million sq mi). It is one of 3 physiographics province in the broad physiographics region of Africa that is densely populated.

A few ergsdot the Sahara’s topography, although some of the sand dunes reach heights of over 180 metres (600 feet) (590 feet).

They are all generated by wind or extraordinary rainfall and are named after them (shatt or chott). Landform Richat Structure in Mauritania.

The Sahara desert is the world’s largest and driest hotspot. To prevent cloud formation, warm and dry upper tropospheric air usually falls below the subtropical ridge.

Light and heat can travel freely because there are no clouds. It is impossible to get rain in the desert since the atmosphere is stable. That means sunny, dry, stable weather with little risk of rain. Convectional showers are difficult to generate due to adjacent, divergent,subtropical high pressure is connected with dry airs mass.

In this vast region, the subtropical ridge is the main cause of the hot deserted climates. To challenge Chile’s and Peru’s Atacama Desert, the Libyan Desert’s descending wind is the most powerful and effective.

The eastern Sahara experiences less rainfall and less cloud cover. Above the Sahara, the primary air mass is the hot, dry continental tropical air mass. Heat waves and sandstorms develop in the North African desert.

There are traces of human habitation along the desert’s edges dating back to the last glacial epoch. Rock art from the Bubaline, Kel Essuf, Round Head, Pastoral, Caballine, and Cameline eras may be found in the Central Sahara area. When it was wetter, the Sahara was drier. In Algeria, half of the 30,000 petroglyphs feature river creatures, such as crocodiless.

Fossils of afrovenator or Jobaria & auranosaurus have been discovere in this region. Current the sahara is devoid of vegetation save for the valley or Oases & northern highlands and where mediterraneean species such as olives trees grow.Axial changes enhanced temperatures and decreased precipitation, triggering North Africa’s fast desertification around 5,400 years ago, it was long supposed.

The Saharans are a diverse people. Znag (named after the archaic Zenaga language) is just one of the several Arabized Amazi communities that still exist. Fula/Fulani (French: PUL; Fula: FULE) are among the most populous ethnic groups in the country.

The Saharan dialects are Arabic. Languages belonging to the afro-asian or hamito-Semitic language family include Berber and its variants .Its residents, unlike their neighbours in West Africa, follow Tuareg and Berber leaders and cultures, with little influence from the French language. Because of the French colonial control, the Third and Fourth republics restructured the territory,artificially dividing an otherwise permeable zone. Local clientele were dealt with in Arabic. To resolve conflicts and communicate between agencies, the French government hired interpreters, who “recorded a space of intercultural mediation” and helped preserve indigenous culture, says Keenan.
