Question

E) Give reason why.
1. Waterfalls are not found in the lower course of a river.

Answer 1

Answer:

Waterfalls are commonly formed in the upper course of a river where lakes fall into in steep mountains.

Because of their landscape position, many waterfalls occur over bedrock fed by little contributing area, so they may be ephemeral and flow only during rainstorms or significant snowmelt.

Hope it helps.
