Kibaha – Solved Photography | Form Four | Pre-Necta 2026

Answers

a) Name the landform shown in the photograph:
Mushroom rock (also called a rock pedestal).

b) Name the geographical process responsible for its formation:
Wind erosion, particularly abrasion/corrasion by wind-blown sand.

c) State two other landforms formed by the same process:

1. Yardangs
2. Ventifacts (wind-faceted rocks)

d) In which climatic region are we likely to find the landform?
Arid and semi-arid (desert) climatic regions.

e) State two physical conditions that favour the formation of the landform:

1. Strong, persistent winds carrying sand particles.
2. Rocks with different levels of hardness, especially softer rock near the ground that is eroded faster than harder rock above.

In short:
Mushroom rock → wind erosion/abrasion → arid/semi-arid climate → strong winds + differential rock resistance.
