#7. What’s the coldest temperature recorded on Mercury, the closest planet to the Sun?
Although Mercury gets very hot on its sunward side, the far side is quite cool. But the coldest parts of Mercury are deep craters near the poles that never, ever get any sunlight.
#8. What’s the highest mountain on Earth?
Mount Everest is the highest mountain on Earth and it’s currently 8,849m tall. Because of continental plates moving, Mount Everest is still growing taller!
#9. 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!
#10. True or false: the human blood is red because it contains the protein haemoglobin.
Haemoglobin is found in your red blood cells. This protein contains iron, which helps to attract oxygen molecules from the air you breathe.
