Practice objective / multiple choice question 1 from the 2022 Neco Model Questions Vol1 Geography examination.
A river drops 720 m over a horizontal distance of 120 km before reaching a plain. The region experiences a uniform tectonic uplift of 0.12 mm/yr. The river's erosion rate (mm/yr) can be approximated by \(E = 0.25 \times G\), where \(G\) is the river gradient expressed in percent. If the uplift rate exceeds the erosion rate, a gorge is formed; otherwise a V‑shaped valley develops. Determine the landform that will be produced by this river.
