Algeria - Geography

Geography

Algeria is the largest country in Africa, the Arab world, and the Mediterranean Basin. Its southern part includes a significant portion of the Sahara. To the north, the Tell Atlas form with the Saharan Atlas, further south, two parallel sets of reliefs in approaching eastbound, and between which are inserted vast plains and highlands. Both Atlas tend to merge in eastern Algeria. The vast mountain ranges of Aures and Nememcha, occupy the entire north eastern Algeria and are delineated by the Tunisian border. The highest point is Mount Tahat (3,003 m).

Algeria lies mostly between latitudes 19° and 37°N (a small area is north of 37°), and longitudes 9°W and 12°E. Most of the coastal area is hilly, sometimes even mountainous, and there are a few natural harbours. The area from the coast to the Tell Atlas is fertile. South of the Tell Atlas is a steppe landscape, which ends with the Saharan Atlas; further south, there is the Sahara desert.

The Ahaggar Mountains (Arabic: جبال هقار‎), also known as the Hoggar, are a highland region in central Sahara, southern Algeria. They are located about 1,500 km (932 mi) south of the capital, Algiers and just west of Tamanghasset. Algiers, Oran, Constantine, Tizi Ouzou and Annaba are Algeria's main cities.

Algeria is the biggest country in Africa, followed by Democratic Republic of Congo. More than 90% of its surface is covered by the Sahara desert.
