Match each African geographical region listed on the left with its primary demographic density characteristic and environmental driver on the right.
- Nile River Delta and ValleyHigh population density concentrated along fertile alluvial soils and perennial river irrigation
- Sahara and Namib DesertsVery low population density caused by hyper-aridity and severe scarcity of surface water
- East African Volcanic HighlandsHigh rural population density sustained by fertile volcanic soils and reliable highland rainfall
- Witwatersrand Industrial BeltHigh population density driven by mineral wealth, industrialization, and urban employment
Answer
The Nile Delta and Valley pairs with high population density on fertile alluvial soil; Sahara and Namib Deserts pair with low density due to hyper-aridity; East African Highlands pair with high rural density on volcanic soil; and Witwatersrand pairs with high density driven by mineral wealth and industrialization.
Each African region exhibits population densities reflecting its specific natural resource endowment or physical environment: irrigation and alluvium along the Nile Valley, severe water scarcity in the Sahara/Namib, rich volcanic agricultural soils in East African highlands, and mining/industrial urban pull in Witwatersrand.
