Explain why upper‑course landforms like waterfalls and gorges form using step‑by‑step diagrams that show how resistant rock, plunge pools and undercutting create dramatic vertical features.

Understand how interlocking spurs are created by vertical erosion through clear modelling that helps pupils visualise how rivers cut downwards around hard rock outcrops in steep valleys.

Analyse the transition to the middle course and the development of meanders by linking increased lateral erosion, reduced gradient and greater discharge to the formation of sweeping bends.

Apply your knowledge to annotate complex landform diagrams so pupils can confidently label processes, features and sequences — a key GCSE exam skill.

This lesson is visually rich, exam‑focused, and packed with high‑quality diagrams, giving pupils a strong understanding of how river landscapes evolve from steep uplands to wider, more dynamic middle‑course valleys.
