Match each physical region of Nigeria listed on the left with its corresponding geological structure and drainage characteristic on the right.
- Jos PlateauHigh basement complex structural dome acting as Nigeria's main hydrographic center with a prominent radial drainage pattern.
- Biu PlateauVolcanic plateau capped by extensive tertiary/quaternary basalt flows, forming a major watershed for tributaries of the Hawal and Gongola rivers.
- Sokoto PlainsSedimentary basin underlain by Cretaceous and Tertiary rocks, characterized by cuesta landforms and drained by the Rima river system.
- Cross River BasinStructural lowland trough underlain by marine sediments, drained by streams originating from the Oban Hills and Western Cameroon highlands.
Answer
Jos Plateau corresponds to the high basement complex dome with radial drainage; Biu Plateau corresponds to the basaltic volcanic plateau forming a watershed for Hawal and Gongola rivers; Sokoto Plains corresponds to the sedimentary basin with cuestas drained by the Rima system; and Cross River Basin corresponds to the structural lowland trough drained from the Oban Hills and Western Cameroon highlands.
Each physical region in Nigeria possesses a unique combination of rock geology and drainage patterns: the Jos Plateau is a basement dome with radial drainage; the Biu Plateau is a volcanic basaltic upland; the Sokoto Plains consist of sedimentary cuestas drained by the Rima; and the Cross River Basin is a lowland trough fed by the Oban Hills and Cameroon highlands.
