Question

State three ways in which a waterfall may form.

Answer 1

1. When a river’s channel passes over horizontally underlying hard resistant rocks.
2. When a river enters into a valley through an escarpment.
3. When a river plunges into the lower coastal land from a plateau.
4. Along coasts where mountains reach the coastline through a cliff.
5. Waterfalls may occur in the glaciated highlands where rivers flow from hanging valleys and plunge into the floor of U-shaped valleys.
6. When a landslide blocks a river forming a barrier lake, a waterfall may occur at the point of overspill.
