Question

Mention any 3 reasons why most rivers in west Africa is not navigable

Answer 1

3 reasons why most rivers in West Africa are not navigable are waterfalls, weeds, and seasonal.

• Waterfalls: The presence of waterfalls in the course of rivers in West Africa makes transportation by rivers difficult.
• Weeds: The presence of aquatic plants like weeds, otherwise known as pond scum are present in the rivers forming a green sheet over them, thus making navigation difficult.
• Being seasonal: Most of the rivers in West Africa are seasonal, due to which they dry up during summer and hence transportation is impossible.
