Could you accept United kingdom/UK for "Great Britain"?

The UK is not an island

I get that Australia is considered a continent but it is also considered an island given that it is a continent not connected an any way to another continent like the others with the exception of Antarctica.. which should also be considered an island given the definition of an island.

Yes, but technically Africa, North America, and South America aren't connected to any other continents either.

Don’t know what maps you’ve been using… it’s certainly possible to walk from Africa to Asia and Europe, and the Americas have a single road from top to bottom. If you’re referring to the canals, then by your logic there must be hundreds more “islands” all over the world which nobody thinks of as “islands” at all

Good quiz. Can't agree with dcmd that Australia and Antarctica can be considered islands. His argument doesn't make sense. An island is land separate from a continental landmass and which is entirely surrounded by water.

+1 on accepting UK for Great Britain although it's legally incorrect.

Also, please consider "papua new guinea" for new guinea.

Both of these are wrong though. The UK and Papua New Guinea are Countries. Great Britain and New Guinea are Islands. Great Britain doesn't include Northern Ireland and Papua New Guinea doesn't include the Indonesian Area of New Guinea.

Great quiz. Nice to have a mix of easier and harder geographical features.

One question though. Shouldn't Philippine Trench also be acceptable for Galathea Depth?

Overall, great quiz. Some columns were easy with a bit of geography knowledge, and some were crazy hard!

I got all the rivers and lakes. Would have gotten all the islands if "Britain" were accepted for Great Britain. Looks like more than half of people missed that one, probably for the same reason. "Britain" should be accepted.

After the Mariana Trench, I just started guessing names of places that are near oceanic plate boundaries and I lucked out with the Japan Trench.

A gripe though: By what definition is Antarctica not a desert? If you're not counting cold deserts, then the Gobi shouldn't count either.

There are many islands in the British Isles, but the largest of them is called Great Britain
