Concept:African rivers share typical physical features, but great depth is not one of their general characteristics.
Explanation:Most African rivers have their sources in the interior highlands.
Their courses often include rapids and waterfalls, especially along the upper stages.
The volume of water in these rivers changes with the seasons due to rainfall patterns.
However, large depth is not a common feature of African rivers.
Many of these rivers are shallow in places and contain sandbars.
This shallowness makes navigation difficult for large ships.
Therefore, the option that does not describe African rivers is the one claiming they have great depths.
