Final answer:
The Sahel is a semiarid transitional zone south of the Sahara that is hot and dry with some rain, stretching across West/Central Africa.
Step-by-step explanation:
South of the Sahara is the Sahel, a semiarid belt of land that separates the desert in the north from the savanna in the south. The Sahel is a transitional zone that stretches some 3,300 miles across the continent. The Sahel is known for being hot and dry, but it also receives some rain, particularly the farther south you go, which sees a longer rainy season and more temperate climate suitable for various forms of vegetation and pasturage.
