Zorluk: OrtaEnvironmental Hazards and Resource Management in Nigeria

Match each distinct geographical region of Nigeria listed on the left with its most predominant environmental hazard on the right.

  • Southeastern Cuesta Landscapes (e.g., Nanka, Agulu, Oko)Severe gully erosion driven by intense rainfall on friable sandstone parent materials
  • Far Northern Sudan-Sahel Belt (e.g., Sokoto, Jigawa, Borno)Encroaching desertification and sand dune movement exacerbated by overgrazing and wood cutting
  • Niger Delta Lowland Swamps (e.g., Bayelsa, Rivers, Delta)Crude oil spillage and mangrove degradation resulting from petroleum extraction infrastructure
  • Jos High Plateau Surface (Plateau State)Land dereliction with abandoned mine paddocks and toxic spoil heaps from historical tin extraction

Cevap

Southeastern Cuesta Landscapes matches with severe gully erosion on friable sandstone; Far Northern Sudan-Sahel Belt matches with encroaching desertification and sand dune movement; Niger Delta Lowland Swamps matches with crude oil spillage and mangrove degradation; Jos High Plateau Surface matches with land dereliction from historical tin extraction.
Each ecological and economic zone in Nigeria faces distinct hazards dictated by climate, geology, and human activity: the Southeastern cuestas suffer gully erosion due to weak sandstone and heavy rains; the Far North experiences desertification from drought and vegetation loss; the Niger Delta faces oil spillage due to petroleum extraction; and the Jos Plateau endures land dereliction from open-cast tin mining.

Adım Adım Çözüm

1
Analyze the physical relief, soil geology, and rainfall patterns for Southeastern Nigeria.
Identify that unconsolidated sandstone under heavy rainfall generates massive gully systems in places like Agulu-Nanka.
Geological substrate and climate dictate the susceptibility to gully development.
2
Examine the climate zone and vegetation of extreme Northern Nigeria.
Link low annual rainfall, high evapotranspiration, and human pressure (wood harvesting, overgrazing) to desertification.
Arid climate combined with land overuse accelerates the spread of desert-like conditions.
3
Locate the primary region of economic petroleum activities in Nigeria.
Associate the Niger Delta coastal swamps with crude oil leaks, pipeline vandalization, and aquatic pollution.
Oil infrastructure is concentrated in the Niger Delta river marine ecosystems.
4
Identify historical mineral extraction zones in the central highlands.
Match the Jos Plateau with surface tin/columbite mining legacy features like paddocks and spoil heaps.
Open-cast mining leaves un-reclaimed artificial pits and degraded land surfaces.
