The correct answer is B) It extends across the continent from the Red Sea to the Atlantic Ocean.
The Sahel is located close to the Sahara but travel is easier and the climate is not as hot. The location of the Sahel encouraged the development of trade routes because it extends across the continent from the Red Sea to the Atlantic Ocean.
West Africa can be divided into five different belts or regions, depending on the weather and the vegetation. Up north is the Sahra region, followed by the Sahel, Sudan, Guinean, and Guinea-Congolian. The Sahel is the region that starts on the Atlantic Ocean coast of Senegal and runs through Sudan and the Red Sea. Its climate and much less hot temperatures facilitated trade routes for merchants that considered impossible to cross the Sahara due to extreme weather conditions.
