What continent has the most vowels?

This is a bit of a trick question! Continents themselves don't have vowels.

Here's why:

* Continents are landmasses: They are geographical features, not words.

* Vowels are sounds: They are part of language, not physical geography.

So, you could say that no continent has the most vowels, because the concept doesn't apply.

Perhaps you were thinking about which continent has the most languages with vowels? That's a more interesting question!
