Apparently the steppe is an area within the plateau, accounting for ~25% of its area (was wondering myself so looked it up)

And strictly speaking, a fault is not a landform. Geologic feature, sure.

It's odd that you select Kilimanjaro, a volcano, for the "mount" clue, and then expect the entry of volcano for a different answer.

Also, Biscayne is a bay as well as a key. Possibly a key that is not also something else would be a better clue.

MiracleMax

Further research indicates that, despite the name, Biscayne is not a key. Rather, it is a barrier island, with a significantly different geological makeup than the keys. I would definitely pick a different answer for this one.

How US-centric should it be? And how US-centric would it have to be in order to be considered "slightly" too US-centric as opposed to "far" too much so?

Four of the least guessed five answers are places in the US. That would indicate the quiz is too US-centric for the average quiz taker.

Stoggler

Level 56
Mar 23, 2026
It's not famous or recognisable at all outside the US (or at best North America).

Pond is a difficult one, because ponds are generally small and not significant enough to be sufficiently well known for a quiz like this. I'd suggest replacing pond with a different word.
