Describe the main physical features of africa

Sandy and hot around Egypt. And some where around south Africa is a rain forest

Northern Africa is covered by a huge, hot, dry desert (the Sahara). 
Right below that is the Sahel, which transitions between the Sahara and savanna.
From Morocco to Tunisia, there's a long mountain range.
Most of central Africa is savanna, which gets enough rain to support the grassy landscape.
Further south, Africa is covered by moist, humid rainforest.
