Match each physical region of Nigeria listed on the left with its correct relief and drainage characteristic on the right.
- Eastern ScarplandsAsymmetrical cuesta topography that forms a distinct drainage divide between the Anambra and Cross River basins
- Benue TroughLinear sedimentary structural rift valley characterized by extensive alluvial floodplains and major tributary confluences
- High Plains of HausalandBroad crystalline basement plain punctuated by inselbergs, serving as the headwater region for northern river systems
- Oban HillsRugged crystalline basement complex massif in southeastern Nigeria drained by dense coastal river networks
Answer
Eastern Scarplands matches the asymmetrical cuesta topography; Benue Trough matches the linear sedimentary structural rift valley; High Plains of Hausaland matches the broad crystalline basement plain with inselbergs; Oban Hills matches the rugged crystalline basement complex massif in southeastern Nigeria.
Each physical region of Nigeria is correctly paired based on its distinctive geological foundation, relief forms, and hydrographic function: the Eastern Scarplands exhibit cuesta landforms that divide river basins; the Benue Trough is a sedimentary rift valley with broad alluvial floodplains; the High Plains of Hausaland form an extensive basement plateau with inselbergs serving as a northern watershed; and the Oban Hills represent a dissected crystalline highland in the southeast.
