Explanation:

The Niger River is one of the largest rivers in Africa, by length, volume of water, and by its basin. It is by far the largest river in Western Africa and it is extremely important for the region. This river passes through multiple countries, starting at the Guinea Highlands and ending at the southern coast of Nigeria. The Niger River has a shape that reminds of a half circle, starting from south, moving towards northeast, then toward southeast, and finally toward south. This makes the northernmost point of the river to be in its middle part, with Timbuktu being the largest settlement on the banks of this river's northernmost point.
