A nomad is someone who travels on and on for fresh pasture for farming etc anyways it relates to the spread since they would go from place to place telling people about Islam spreading there religion far and these nomads would tell other nomads and those on and on it was easier to spread than villages since villages are closed up and people don't move but the nomads are constantly moving people
The Black Sea and Aegean Sea (Hopefully this is correct!)
I believe its the <span>consist mountains thick with trees, rivers and poor rocky soil that was difficult to farm and unsuitable for crops.
I hope this helps :)
