  Sudan is situated in North Africa, with an 853 km (530 mi) coastline bordering the Red Sea. It has land borders with Egypt, Eritrea, Ethiopia, South Sudan, the Central African Republic, Chad, and Libya. With an area of 1,886,068 km 2 (728,215 sq mi), it is the third-largest country on the continent (after Algeria and Democratic Republic of the Congo) and the fifteenth-largest in the world.
  
  Sudan lies between latitudes 8° and 23°N. The terrain is generally flat plains, broken by several mountain ranges. In the west, the Deriba Caldera (3,042 m or 9,980 ft), located in the Marrah Mountains, is the highest point in Sudan. In the east are the Red Sea Hills.
  
  The Blue Nile and White Nile rivers meet in Khartoum to form the Nile, which flows northwards through Egypt to the Mediterranean Sea. The Blue Nile's course through Sudan is nearly 800 km (497 mi) long and is joined by the Dinder and Rahad Rivers between Sennar and Khartoum. The White Nile within Sudan has no significant tributaries.
  
  There are several dams on the Blue and White Niles. Among them are the Sennar and Roseires Dams on the Blue Nile, and the Jebel Aulia Dam on the White Nile. There is also Lake Nubia on the Sudanese-Egyptian border.
  
  Rich mineral resources are available in Sudan including asbestos, chromite, cobalt, copper, gold, granite, gypsum, iron, kaolin, lead, manganese, mica, natural gas, nickel, petroleum, silver, tin, uranium and zinc. In 2015, Sudan's gold production was 82 metric tons.
