Match each major Nigerian soil group on the left with its primary geographical zone of distribution and pedological characteristic on the right.
- Ferrallitic Soils (Latosols)Dominant in the high-rainfall Southern Rainforest belt, characterized by deep weathering, heavy leaching, and high acidity.
- Ferruginous Tropical SoilsPrevalent across the Guinea Savanna on crystalline Basement Complex rocks, marked by a silica-rich layer and tendency to form surface crusts.
- Hydromorphic (Fadama) SoilsExtensively found across the Niger-Benue river basins and low-lying delta floodplains, characterized by high water tables and rich organic alluvial deposits.
- Regosols and Semi-Arid Brown SoilsRestricted to the semi-arid northern boundary zones such as Sokoto and Chad Basin, formed under sparse vegetation with low organic content.
Cevap
Ferrallitic Soils match with the Southern Rainforest belt; Ferruginous Tropical Soils match with the Guinea Savanna on Basement Complex rocks; Hydromorphic Soils match with river basins and low-lying floodplains; Regosols and Semi-Arid Brown Soils match with the northern boundary zones.
Each Nigerian soil group reflects specific climatic, topographic, and lithological controls: Ferrallitic soils belong to the humid southern rainforest, Ferruginous tropical soils cover the central crystalline savanna, Hydromorphic soils occupy floodplains and valleys, and Regosols occur in the dry northern margins.
