Difficulty: MediumRelief, Physical Regions, and Drainage Systems of Nigeria

Match each physical region of Nigeria listed on the left with its corresponding relief and drainage characteristic on the right.

  • Sokoto PlainsGently undulating sedimentary lowland in the northwest drained by the Sokoto-Rima river system.
  • Eastern HighlandsHigh mountain ranges along the eastern border containing Mount Dimlang (Vogel Peak).
  • Niger-Benue TroughVast linear alluvial valley featuring floodplains, braided channels, and river terraces.
  • Niger DeltaLow-lying coastal region characterized by a complex network of distributaries and mangrove swamps.

Answer

Sokoto Plains matches with the gently undulating sedimentary lowland in the northwest; Eastern Highlands matches with the high mountain ranges containing Mount Dimlang; Niger-Benue Trough matches with the vast linear alluvial valley; Niger Delta matches with the low-lying coastal region of distributaries.
The correct pairings accurately reflect Nigeria's regional geography: the Sokoto Plains are a northwestern sedimentary basin drained by the Sokoto-Rima system; the Eastern Highlands harbor Nigeria's elevated peaks like Mount Dimlang along the eastern border; the Niger-Benue Trough is a major structural valley featuring alluvial floodplains; and the Niger Delta is a coastal deposit defined by distributary networks and mangrove vegetation.

Step-by-Step Solution

1
Analyze the geological structure and location of each physical region.
Identified Sokoto Plains as northwestern sedimentary lowlands, Eastern Highlands as eastern border mountains, Niger-Benue Trough as a central structural valley, and Niger Delta as a southern coastal wetland.
Topography and bedrock composition directly govern the relief features and drainage behaviors of Nigerian regions.
2
Match each physical region to its defining drainage and relief description.
Paired Sokoto Plains to the Rima system lowland, Eastern Highlands to Vogel Peak, Niger-Benue Trough to the alluvial floodplain valley, and Niger Delta to coastal distributaries.
Each description highlights exclusive landform markers and river configurations specific to that region.
