Explanation:
Atlas Mountains, series of mountain ranges in northwestern Africa, running generally southwest to northeast to form the geologic backbone of the countries of the Maghrib (the western region of the Arab world)—Morocco, Algeria, and Tunisia. They extend for more than 1,200 miles (2,000 kilometres), from the Moroccan port of Agadir in the southwest, to the Tunisian capital of Tunis in the northeast. Their thick rim rises to form a high sill separating the Mediterranean basin to the north from the Sahara to the south, thus constituting a barrier that hinders, without completely preventing, communication between the two regions. Across the mountains filter both air masses and human migrations. It is, however, only in the east–west direction that the Atlas Mountains facilitate movement. These are the conditions that create at the same time both the individuality and the homogeneity of the Atlas countries. Although the Saharan region is more likely to be described as the archetypal North African habitat, it is the well-watered mountains north of this vast desert that provide the foundation for the livelihood of most of the peoples of North Africa and a striking green or white background for many North African towns.

The northern section is formed by the Tell Atlas, which receives enough rainfall to bear fine forests. From west to east several massifs (mountainous masses) occur. The first of these is Er-Rif, which forms a half-moon-shaped arc in Morocco between Ceuta and Melilla; its crest line exceeds 5,000 feet (1,500 metres) above sea level at several points, reaching 8,058 feet at Mount Tidirhine. East of the gap formed by the Moulouya River the Algerian ranges begin, among which the rugged bastion of the Ouarsenis Massif (which reaches a height of 6,512 feet), the Great Kabylie, which reaches 7,572 feet at the peak of Lalla Khedidja, and the mountains of Kroumirie in Tunisia are all prominent.
The southern section, which is subject to desert influences, is appropriately called the Saharan Atlas. It includes in the centre a palisade formed by shorter ranges, such as the Ksour and Ouled-Naïl mountains, grouped into massifs between two mighty ranges—the Moroccan High Atlas to the west and the Aurès Mountains to the east. The High Atlas culminates in Mount Toubkal at 13,665 feet (4,165 metres), the highest point in the Atlas Mountains, which is surrounded by high snowcapped peaks; the Aurès Mountains are formed of long parallel folds, which reach a height of 7,638 feet at Mount Chelia.
The Tell Atlas and the Saharan Atlas merge in the west into the long folds of the Middle Atlas and in the east join together in the Tébessa and Medjerda mountains.
Geology
If the relief of the Atlas region is relatively simple, its geology is complex. In essence, the two Atlases comprise two different structural regions.
The Tell Atlas originally arose out of a basin filled with sediment, which was dominated to the north by a marginal rim, of which the massifs of Tizi Ouzou, Collo, and Edough are the remnants. Its elevation took place during a lengthy mountain-building process that was marked by upheavals in the Paleogene and Neogene periods (i.e., about 65 to 2.6 million years ago); over the cluster of folds that were uplifted from the rift valley were spread sheets of flysch (deposits of sandstones and clays), which were carried down from the north over the top of the marginal rim. Thus the Tell Atlas represents an example of a young folded mountain range still in the process of formation, as is shown by the earth tremors to which it is subject.

Explanation:
The Atlas Mountains (Arabic: جِبَال ٱلْأَطْلَس, romanized: jibāl al-ʾaṭlas /ʒibaːl al atˤlas/) are a mountain range in the Maghreb. It separates the Mediterranean and Atlantic coastlines from the Sahara Desert. It stretches around 2,500 km (1,600 mi) through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, which is in central Morocco, with an elevation of 4,167 metres (13,671 ft).[1] The Atlas mountains are primarily inhabited by Berber populations.[2] The terms for 'mountain' are adrar and adras in some Berber languages. These terms are believed to be cognates of the toponym Atlas. The mountains are also home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct.
