Zorluk: OrtaRelief, Physical Regions, and Drainage Systems of Nigeria

Complete the statement by providing the correct geographical terms associated with the physical relief and drainage divide of southeastern Nigeria.

Cevap:The prominent relief feature in southeastern Nigeria forming an asymmetrical ridge that stretches from Nsukka through Enugu is known as the 【Udi】 Cuesta, which forms a major drainage divide between the Anambra River basin and the 【Cross】 River basin.

Cevap

The correct terms to complete the statement are Udi (or Udi-Nsukka) for blank 1 and Cross for blank 2.
The Udi Cuesta (or Udi-Nsukka Plateau) is a classic landform in southeastern Nigeria. Running north to south near Enugu, its steep scarp faces east while its gentle dip slope tilts west. It serves as the drainage divide between the Anambra River (flowing west into the River Niger) and the Cross River (flowing east and south into the Gulf of Guinea).

Adım Adım Çözüm

1
Identify the prominent escarpment (cuesta) in southeastern Nigeria stretching across Nsukka and Enugu.
The Udi Cuesta (also known as the Udi-Nsukka Plateau) is the primary landform forming a steep scarp slope facing east toward Enugu.
Physical geography of Nigeria identifies the Udi ridge as the major cuestiform relief in the southeastern structural belt.
2
Determine the major river drainage basins separated by this escarpment.
The dip slope drains westwards into the Anambra River basin, while the scarp slope drains eastwards into the Cross River basin.
The ridge acts as a hydrological watershed dividing the Anambra system (tributary to the Niger) from the Cross River system.
