How did Islam spread into West Africa? Islamic armies invaded West Africa and taught the people about Islam.
Islamic teachers came to West Africa to build schools and teach Islam.
Islam was adopted in West Africa through interactions with Muslim traders.
The West African people traveled to southern Africa to learn more about Islam.

Following the conquest of North Africa by Muslim Arabs in the 7th century CE, Islam spread throughout West Africa via merchants, traders, scholars, and missionaries, that is largely through peaceful means whereby African rulers either tolerated the religion or converted to it themselves.

Explanation:

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

they were chasing the bread.
