Mauritania ,officially the Islamic Republic of Mauritania, is a country in North-West Africa. It is bordered by the Atlantic Ocean on the west, by Senegal on the southwest, by Mali on the east and southeast, by Algeria on the northeast, and by Western Sahara on the northwest (most of which is occupied by Morocco). It is named after the ancient Berber kingdom of Mauretania. The capital and largest city is Nouakchott, located on the Atlantic coast.
Mauritania is generally flat, its 1,030,700 square kilometers (397,850 sq mi) forming vast, arid plains broken by occasional ridges and clifflike outcroppings. A series of scarps face southwest, longitudinally bisecting these plains in the center of the country. The scarps also separate a series of sandstone plateaus, the highest of which is the Adrar Plateau, reaching an elevation of 500 meters (1,640 ft). Spring-fed oases lie at the foot of some of the scarps. Isolated peaks, often rich in minerals, rise above the plateaus; the smaller peaks are called guelbs and the larger ones kedias. The concentric Guelb er Richat (also known as the Richat Structure) is a prominent feature of the north-central region. Kediet Ijill, near the city of Zouîrât, has an elevation of 1,000 meters (3,280 ft) and is the highest peak. |
