Answers
- It's 71 days, says the Met Office. It snowed somewhere in the UK every day from Boxing Day, 1962, until 6 March 1963.
- It's six, as most snowflakes are hexagonal. Three or 12-sided snowflakes can also fall, says leading snow-crystal scientist, Kenneth Libbrecht. Snow can also fall as simple prisms, columns, bullet shapes and needles.
- It's picture 1 - flakes known as stellar dendrites form the powder snow popular with skiers. The most detailed snowflake classification sytem was published by meteorologists C Magono and CW Lee in 1966, and included 80 types of snow.
- Higher gears aid the tyres gripping when moving off on packed ice and snow, says the driving school BSM. It's a myth that staying in a lower gear is safer.
- It's cat litter, used to grit paths and pavements. Sales of carrots rose by 60% and hot chocolate by 27% during last February's cold snap, says home-delivery service Ocado.
- Snowflakes get smaller as the temperature drops, because they remain in a dry, powdery form. At higher temperatures, closer to 0C, they clump together to become larger and wetter - and make better snowballs.
- It's "white shot", which doesn't exist. The other two are legitimate types of snow and recognised by the Met Office.
