Question 1 · 1 mark · Difficulty 1/3
Fig. 5.2 shows a cross-section of a river valley. [Diagram shows: V-shaped valley with steep sides, interlocking spurs, narrow channel with large boulders] In which course of the river was this cross-section most likely taken?
- Upper course
- Middle course
- Lower course
- At the river mouth
Show answer & explanation
✓ Answer: A — Upper course
Award 1 mark for identifying the upper course based on the characteristic features shown. V-shaped valleys, interlocking spurs, narrow channels, and large boulders are all features of the upper course where vertical erosion dominates and the river has high gradient but low discharge. B, C, and D are incorrect — middle and lower courses have wider, flatter valleys and finer sediment.
