Translation:Africa is the continent south of Europe.
First off, I want you to know that I mean no disrespect =) I suspect that in your native tongue, the examples you've given might be correct; however, to a native English speaker, they are a little odd-sounding... or rather just a bit jumbled.
"Africa is the continent south of Europe." (Or) "The continent south of Europe is Africa."
These would both work in English. I can't really think of any other proper way to say it in English. And in modern English, we really don't use the word "to" interchangeably with the word "of." "To" is most often used to describe either movement or when someone receives something. I can't recall the technical terms for this, I'm afraid lol But I hope this helps ^^ Lykke til!
