I love learning things about Africa. Can you tell me some things I might not know? 
 Africa, because of its landmass it is classified as the second largest continent in the world. In fact, it holds about 20% of the Earth's total land. 
 I didn't know it was that big. Do you have anything else on their Geology and geography? 
 It is the hottest continent on Earth and consists mostly of dry-lands and deserts. Africa sits on the Nubian Plate. 
 How much rainfall do they typically get during the year? 
 Sorry, but I don't know about that but I can tell you about the Somali plates. 
 Great. I'd love to hear about those. 
 It is a plate in Africa that rifts with the African plate. They call this are the East African Rift. 
 That's very interesting. What do you know about the Demographics? 
 From what I can tell the demographics contain groups comprised from a population that represents around 15% of the world. 
 What's the dominant religion there? 
 Islam is the largest religion, followed by Christianity. -World Book Encyclopedia. 
 I'm surprised that Christianity is second behind Islam. Do you have any other facts on Demographics for me? 
 Early Arabs brought Islam to North Africa. 
 That makes sense. Thanks for your help today. 
 You're welcome.
