How did geography affect migration, cultural development, and trade in Africa?

Africa had a lot of deserts that made trade harder so the cultures of africa even if close by weren't that similar

The geographical features effected this development a lot with rivers and trade countries. For one the Congo, the Niger and the Zambezi river were major trade routes which traders from other countries could use to import goods and trade with Africa. Africa was is also surrounded by the major trade countries of Europe and Asia. Africa soon started doing a lot of trading thus being shaped by other traders around them.
