Ah Czechia! You sneaky little meteorite-filled country! Interesting quiz! I wonder if the USA is highest because people are more likely to report meteorite landings, or if there’s some other reason.
If you're looking for answers, I found this good article about meteorite observers in the US by the American Meteor Society: The Early Years of Meteor Observations in the USA. It contains keys to explain how so many meteorites have been observed since the 18th century, particularly thanks to partnership between academic astronomers and amateurs observers through the country.
Haha! Cool quiz, and funny drawing. The third block helps a lot in finding the missing countries. A quiz that could have been a simple and maybe boring for some quiztakers top 20, like hundreds others, but which is definitely more than that. Well done, and nominated!
You would assume its just a list of the biggest countries of the world. Maybe excluding deserted areas. But I guess the people in the Central African Republic have other things to worry about than getting their meteorite reporting system up to scratch...
This 3rd block is maybe too helpful so I plan to delete it if results don't fall under 90% ^^
