  Mali is a landlocked country in West Africa, located southwest of Algeria. It lies between latitudes 10° and 25°N, and longitudes 13°W and 5°E. Mali borders Algeria to the north-northeast, Niger to the east, Burkina Faso to the south-east, Ivory Coast to the south, Guinea to the south-west, and Senegal to the west and Mauritania to the north-west.
  
  At 1,240,192 square kilometres (478,841 sq mi), Mali is the 24th-largest country in the world and the eighth-largest country in Africa. It is comparable in size to South Africa or Angola. Most of the country lies in the southern Sahara Desert, which produces an extremely hot, dust-laden Sudanian savanna zone. Mali is mostly flat, rising to rolling northern plains covered by sand. The Adrar des Ifoghas massif lies in the northeast.
  
  Mali lies in the torrid zone and is among the hottest countries in the world. The thermal equator, which matches the hottest spots year-round on the planet based on the mean daily annual temperature, crosses the country. Most of Mali receives negligible rainfall and droughts are very frequent. Late April to early October is the rainy season in the southernmost area. During this time, flooding of the Niger River is common, creating the Inner Niger Delta. The vast northern desert part of Mali has a hot desert climate (Köppen climate classification BWh) with long, extremely hot summers and scarce rainfall which decreases northwards. The central area has a hot semi-arid climate (Köppen climate classification BSh) with very high temperatures year-round, a long, intense dry season and a brief, irregular rainy season. The southern areas have a tropical wet and dry climate (Köppen climate classification Aw).
  
  Mali has considerable natural resources, with gold, uranium, phosphates, kaolinite, salt and limestone being most widely exploited. Mali is estimated to have in excess of 17,400 tonnes of uranium (measured + indicated + inferred). In 2012, a further uranium mineralized north zone was identified. Mali faces numerous environmental challenges, including desertification, deforestation, soil erosion, and inadequate supplies of potable water.
