B overgrazing.
To determine the main cause of desertification in Sub-Saharan Africa, we need to analyze the given options:
A) Deserts: This option suggests that deserts themselves are the main cause of desertification. However, desertification refers to the process of fertile land turning into desert-like conditions, so deserts cannot be the main cause.
B) Overgrazing: Overgrazing occurs when there are too many animals grazing in a particular area, leading to the depletion of vegetation. This can contribute to desertification.
C) Over-burning: Over-burning refers to the excessive burning of vegetation, which can lead to the loss of fertile topsoil and ultimately contribute to desertification.
D) Intense heat: Intense heat alone cannot be considered the main cause of desertification. Although high temperatures can accelerate the process, they are not the sole cause.
E) Heavy rainfall: Heavy rainfall suggests an abundant water supply rather than a lack of it, which is contrary to desertification.
Based on these considerations, it can be concluded that the most likely main cause of desertification in Sub-Saharan Africa is option B: overgrazing. Overgrazing by livestock leads to the removal of vegetation, which in turn results in soil erosion, loss of nutrients, and eventual desertification.
