Match each African geographical region listed on the left with its corresponding population density characteristic and primary environmental driver on the right.
- Nile River ValleyVery high population density sustained by fertile alluvial soils and perennial river irrigation
- Sahara DesertExtremely low population density caused by hyper-arid climatic conditions and severe water scarcity
- Niger DeltaHigh population density influenced by rich natural resources, maritime trade access, and abundant water supply
- Kalahari BasinSparse population density resulting from semi-arid scrubland and limited permanent surface water
Cevap
The Nile River Valley matches with very high population density sustained by fertile alluvial soils and perennial river irrigation; the Sahara Desert matches with extremely low population density caused by hyper-arid climatic conditions and severe water scarcity; the Niger Delta matches with high population density influenced by rich natural resources, maritime trade access, and abundant water supply; and the Kalahari Basin matches with sparse population density resulting from semi-arid scrubland and limited permanent surface water.
Each region correctly aligns with its primary environmental driver of settlement density: the Nile River Valley attracts dense settlement through alluvial irrigation; the Sahara Desert is virtually empty due to hyper-aridity; the Niger Delta has high density owing to water, petroleum, and coastal trade; and the Kalahari Basin has low population density due to semi-arid scrub conditions.
