The Sahel (/səˈhɛl/) is the eco climatic and biogeographic zone of transition in Africa between the Sahara Desert to the north and the Sudanian Savanna to the south. Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea.
Sub-Saharan Africa is, geographically, the area of the continent of Africa that lies south of the Sahara desert. Politically, it consists of all African countries that are fully or partially located south of the Sahara(excluding Sudan, even though Sudan sits in the Eastern portion of the Sahara desert).
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.
