Test Your Geographic IQ

A post by Catholicgauze sent me wandering over to the website of the National Geographic Bee. What a spelling bee is to English, the Geography Bee is to anyone who enjoys geography, maps, and stuff like that.

At the website, I stumbled upon some sample questions, which I'm sharing for those brave enough to test their geographic IQ:

1. Which state has a climate suitable for growing citrus fruits—California or Maine?
2. Which country has the world's largest Muslim population—Indonesia or Mexico?
3. The North Atlantic current brings warm waters from the tropics to the west coast of which continent?
4. What is the term for a part of an ocean or sea that cuts far into the bordering landmass and may contain one or more bays?
5. The port of Rotterdam is built on the delta of which major European river?
6. Which Canadian province produces more than half of the country's manufactured goods?
7. To visit the ruins of Persepolis, an ancient ceremonial capital of Persia, you would have to travel to what present-day country?

Modesty prevents me from saying how many I got right.
