Where I am, climbing the tallest mountain nearby involves a lot of cold and not a lot of oxygen (not that I've done it), and that mountain is not even half the height of Everest.
It's probably because "highest mountain on earth" sounds more impressive (and it's more descriptive) that "highest mountain in Nepal." BTW, it's also in China...
Still, this page is an American one, so the users on this page are more than 4% Americans, so the interests might be slightly more from an American point of view and answers might always remain more US-centric (I like this expression!) than the average. For sure, most non-geographic quizzes would be a lot easier for me, too. Anyway, I still like playing them ;-)
That's such a dumb argument. There are none in India, the most populated country. Denali and maybe Whitney should be included, and we can stretch that to Rainier and Mauna Kea as well but the other two are pushing it. Sad to see that USA gets 6 yet 3 continents go with 1 or fewer
(Something that's repetitive.)
So if the USA has 6, you should just be happy Australia got rounded up to be included.
