Answer:
No, Africa is not a monolith, is in fact the opposite, it is a very diverse culture with hundreds of different cultures living across the continent.
Land plays a very important role when it comes to culture because human communities are shaped by the physical characteristics of the space they live in. People living in the desert will not have the same culture as people living in the rainforest or in the tropical savannah, and since the African continent has many different kinds of land in its territory, it is only natural that there are also many different kinds of cultures in this continent.
