The correct options are
B The Canaries current and the Benguela currents
C The equator passing through the continent
D The absence of mountains
The equator passes through Africa dividing it into two parts. Because of the direct rays of the sun, the climate of Africa is predominantly tropical. The factors that influence the climate are ocean currents, the absence of mountains, east-west extent, and location. The cold ocean currents that flow along the western part of the continent modify the temperature of the adjoining coastal lowlands. The absence of high mountains and other weathers divides permit the free circulation of tropical air.
