Trade winds are responsible for most of the wind patterns over the continent of Africa. Hence the correct option is d.
The predominant global wind responsible for shaping the wind patterns over the continent of Africa is the trade winds. These are steady easterly winds that blow towards the equator from the subtropical high-pressure belts in both the Northern and Southern Hemispheres. Over Africa, the trade winds converge near the equator, forming the Intertropical Convergence Zone (ITCZ).
This convergence results in ascending air, cloud formation, and precipitation, contributing to the development of the African monsoon. The trade winds play a crucial role in driving weather patterns and influencing climate conditions across the continent, making them a key component of Africa's atmospheric circulation system. Hence the correct option is d.
