Quest GiggleHow old is the oldest air trapped in Antarctic ice?
800 thousand years. Each layer is one year's snowfall, so a 3 km core reads like 800 millennia of weather diaries.
How close would your guess have been?
In the game we ask it like this: “Antarctic ice cores trap air bubbles up to how many thousand years old?”
Type a number — scored exactly the way a round in the game is.
The answer
800thousand years
