Does it ever snow in Antarctica?
Kraig Green
Antarctica has an amazing climate. The coldest temperature ever recorded on Earth, -89.2 degrees Celsius, was captured here at the Russian Vostok research station. Such extreme cold brings out some unique and beautiful effects, such as ‘diamond dust’ – a shiny cloud at ground level made up of tiny ice crystals. And yes, it does snow. Antarctica is actually a desert, which means it doesn’t snow very often. When it does, however, the snowstorms can be spectacular and terrifying.
WHY AREN’T FEET MEASURED IN CENTIMETRES OR INCHES?
@LadyLightning
Feet, like any other part of our body, are measured in centimetres. If you’re asking about why shoe sizes are in numbers, there’s an interesting story to this. The standard way to do shoe sizes is to take three times the foot size in inches, and then take away 25, or 12 for kids’ sizes. The reason for this complicated system is because shoes used to be measured not in inches or centimetres, but in an Old English unit called the ‘barleycorn’ that amounts to one-third of an inch.
