Weather modify, desertification resulting from human functions which include overgrazing, deforestation and inappropriate land administration are main factors. Pure local weather cycles also play a task, affecting rainfall patterns and bringing about durations of drought that expand desert regions.
The serirs and regs vary in character in various areas in the desert but are considered to represent Cenozoic depositional surfaces. A distinguished aspect on the plains could be the dark patina of ferromanganese compounds, named desert varnish, that sorts around the surfaces of weathered rocks. The plateaus in the Sahara, like the Tademaït Plateau of Algeria, are usually protected with angular, weathered rock. In the central Sahara, the monotony on the plains and plateaus is damaged by prominent volcanic massifs—such as Mount ʿUwaynat plus the Tibesti and Ahaggar mountains. Other noteworthy formations include the Ennedi Plateau of Chad, the Aïr Massif of Niger, the Iforas Massif check here of Mali, and also the outcroppings from the Mauritanian Adrar region.
