Final answer:
The climate of Sub-Saharan Africa change if one begins in the northernmost part of the region and travels to the southernmost area, which is `the climate becomes warmer and more arid.`
The answer is option ⇒b
Step-by-step explanation:
As one travels from the northernmost part of Sub-Saharan Africa to the southernmost area, there is a noticeable change in climate. The northernmost regions, such as the Sahara Desert, experience a hot desert climate with very limited rainfall.
However, as you move southwards, the climate transitions into a semi-arid or savanna climate, characterized by higher temperatures and a more pronounced dry season. This shift is primarily due to the influence of the Intertropical Convergence Zone (ITCZ) and the changing patterns of air masses and moisture availability.
In the southernmost parts of Sub-Saharan Africa, like the Cape region, the climate becomes even milder, with a Mediterranean climate in some areas. This means that it becomes more temperate, with mild winters and warm summers, and receives more rainfall compared to the arid regions further north. Therefore, the climate becomes progressively warmer and more arid as one travels from the northernmost part to the southernmost area of Sub-Saharan Africa.
The answer is option ⇒b) The climate becomes warmer and more arid.
