True, I forgot to mention that you can also apply both "sur" and "sud" to get "Sudamérica" and "Suramérica" respectively, and the same for "África", and others like "sud/surcoreano", "sud/surasiático", etc.

Answer 2

With cardinal points you can use either as a prefix: suroeste / sudoeste. Apparently, sur- is more common than sud-.

In isolation, you must write sur or Sur, depending on whether it is a relative reference, or an absolute one (i.e. South Pole). Therefore, it is "El sur de California".

Answer 5

I'm not 100% but I think sud is used only as a prefix
