Match each international environmental convention or protocol listed on the left with its primary global environmental focus on the right.

Which soil conservation technique involves plowing and planting along the natural contour lines of a slope to slow surface runoff and reduce soil erosion?

Southern Nigeria's coastal regions experience a double rainfall maximum with a noticeable drop in precipitation during July and August known as the 'August Break' (Little Dry Season). Which atmospheric mechanism accounts for this temporary dry spell while the Inter-Tropical Convergence Zone (ITCZ) is located at its northernmost position over West Africa?

On a topographical map of a river basin drawn to a Representative Fraction (R.F.) scale of $1 : 40,000$, the distance along a proposed drainage channel between two agricultural settlements measures $14.5\text{ cm}$. What is the actual ground distance of the drainage channel in kilometers?

On a topographical map extract, a major river stream crosses a valley where the V-shaped contour lines point towards the north-east. In which cardinal direction is the river flowing?

During an urban spatial survey of a rapidly expanding metropolitan area, geographers notice that industrial zones and distinct socio-economic residential corridors expand outward along major railway lines and highway arteries in wedge-like sectors from the central business district. Which urban land-use model best explains this spatial growth pattern?

The Witwatersrand basin in South Africa is recognized globally as one of the most prolific gold-producing regions in history. Which of the following statements correctly identifies the geological host environment of these gold deposits and a major physical constraint encountered during their extraction?

During the structural evolution of a karst drainage basin, percolating meteoric water enriched with dissolved carbon dioxide descends vertically through unsaturated jointed limestone until it reaches an impermeable stratum. Which of the following correctly identifies the dominant process operating at the water table interface and the resulting subterranean landform?

Match each weathering or mass wasting process listed on the left with its defining mechanism or physical movement characteristic on the right.

In a morphometric analysis of a river basin, a hydrologist counts $32$ first-order streams and $8$ second-order streams using Strahler's stream ordering system. What is the bifurcation ratio between the first-order and second-order streams?

Arrange the following geomorphic stages in the correct sequential order describing the evolution of a pre-glacial river valley into a steep-sided glacial trough (U-shaped valley).

The Earth is composed of distinct internal structural layers and external atmospheric envelopes. Arrange the following layers in sequence starting from the innermost center of the Earth and moving outward into space. Which order correctly represents this progression?

Along the low-lying floodplains of the Niger and Benue Rivers as well as the coastal plains of Nigeria, periodic river flooding deposits rich sediments of silt and clay. Which soil group predominantly characterizes these riverine environments?

During a chain survey along a baseline, a student uses a steel measuring tape that is shorter than its standard designated length. Which type of error will consistently accumulate in the total recorded distance?

During the onset of the rainy season in Nigeria, nomadic Fulani pastoralists migrate with their zebu cattle herds away from the moist vegetation of the Middle Belt back toward the drier Sudan savanna of the Far North. What is the primary environmental factor driving this northward transhumance during the wet season?

In Nigeria's agricultural zonation, states located within the Middle Belt—such as Benue, Nasarawa, and Niger—are major producers of tuber crops like yam and cassava, yet commercial tree crops such as cocoa and oil palm fail to yield sustained economic output in these areas. Which climatic factor is primarily responsible for limiting the commercial cultivation of tree crops in this zone?

Match each agricultural system listed on the left with its primary operational feature on the right.

Two agricultural processing centers in Osun State are separated by an actual ground distance of $7.5\text{ km}$. If the distance between these two centers on a regional planning map measures $15\text{ cm}$, what is the Representative Fraction (R.F.) of the map?

Arrange the following African vegetation zones in descending order of their average annual rainfall, starting from the zone with the highest moisture level to the zone with the driest conditions.

During a prismatic compass survey along a open traverse line $P-Q-R-S$, a student records the following forward bearings (FB) and back bearings (BB):

- Line $PQ$: FB = $045^\circ$, BB = $225^\circ$
- Line $QR$: FB = $130^\circ$, BB = $308^\circ$
- Line $RS$: FB = $220^\circ$, BB = $042^\circ$

Based on these field observations, which of the survey stations is affected by local attraction?
