Try to keep a good pace while doing this time-based quiz. How synchronised are your answers with ours?
#1. How long does it take the Earth to spin on its axis exactly one full rotation?
It takes a bit less than a day for the Earth to complete a full rotation. That’s because the Earth is orbiting the Sun, so it has to rotate a bit further for the Sun to be in the same spot every day.
#2. Jean Calment was the oldest human recorded in recent human history. How old was she when she died in 1997?
Jean Calment was the oldest human recorded in recent human history, and she lived for 122 years and 164 days!
#3. True or false? Our modern time zones were created to make it easier to schedule trains.
True! Up until the 19th century, different towns would set their clocks based on the Sun, so they wouldn’t be set to the same time. This was a big problem for creating train timetables – it was like every station was its own time zone!
#4. Which of the following types of clocks is the most accurate at keeping time?
All the most accurate clocks in the world are atomic. It’s hard to work out exactly which one is the best because they’re found all around the world, and there’s no good way to send clock signals to compare them with.
#5. Which of the following is the science of measuring time?
Chronometry is the science of timekeeping. The name comes from the ancient Greek words chronos (time) and metron (measurement).
