About this Quiz for Teens quiz
This quiz for teens is a fast, fun mix of 15 general knowledge questions picked to be interesting rather than textbook-dull. You get science trivia for teens, a little music and movie trivia, space, the human body, art, languages and one sneaky word puzzle about US state names, all with short explanations so you learn something even when you guess wrong.
The questions start easy and get trickier. Most teens will breeze through the warm-ups, but a few, like the hottest planet or the letter missing from every US state name, catch out plenty of adults too. That makes it a good pick for a classroom filler, a family quiz night, a sleepover challenge or just testing yourself against friends.
Here is how to get the most out of it: play once without looking anything up, check your score, then read the answer key below to see why each answer is right. Share your result and challenge a friend to beat it. If you enjoyed these general knowledge questions for teens, the related quizzes on world and India GK are a good next step.
Fun fact to impress your friends: Venus is hotter than Mercury, even though Mercury is closer to the Sun, because the thick atmosphere of Venus traps heat like a greenhouse.
