This physical geography series is great, thanks! One toughie in each of them (I blame the Venezuelan mesa here) has been enough to keep me off 100% :( One small detail here - the Galapagos clue might better read ".. west of mainland Ecuador", because the islands are part of Ecuador as well.
Accepting the Spanish/Argentine name Iguazú but not the Portuguese/Brazilian name Iguaçu is biased, in my opinion at least. The waterfall is on the Argentine-Brazilian border so both names should be accepted.
Not out of any political beliefs, but mainly due to having spent an extended period of time in Argentina I always go to write Malvinas first, so yes good to see it accepted.
beccimoo, your comment sets me wondering why, and how many different languages should be acceptable for each answer. If you think that any country (or rather, linguistic group) that has ever held a territory should supply an acceptable answer, that could pose a problem for many jetpunk quiz-setters. For example, in this case, the quiz master should also accept "Maloïnes" (I think that's the correct spelling) since the French were there first.
I was stuck at Tierra del _____, so I entered the only Spanish word that sounded right, which was Fuego, and I was correct, although I don't think I have ever heard of Tierra del Fuego before.
Because Iguaçu is the Brazilian Portuguese word, and how I know it - it should be accepted
