“Jeopardy!” premiered in 1964 as a daytime TV show. Due to its growing popularity, it was moved to primetime television in 1984 and Alex Trebek took over as host.  During the show, three contestants battle it out in trivia while answering clues from different categories. They can vary wildly – from basics like history and geography to more odd ones like “Slowly I turned” or “Impostor!”

Several “Jeopardy!” categories contain questions about the planet Earth. 24/7 Tempo went through J! Archives — a site created by fans of the show that lists clues going back to 1984 — to find real clues about Earth.

Wonder how you’d rate on the game show? Take the following pop quiz and see how you stack up. You can test your knowledge in another area — U.S. states: Here are 50 real “Jeopardy!” questions about each state.
