Dry facts about water
Did you know that: - A single drop of rain is 0.5?6.0 mm in diameter. It can never be larger than 6 mm, because at that point it breaks into several smaller drops. Drizzle has smaller drops, about 0.1?0.5 mm.
- An average 5-mm rain drop falls at a rate of 9 metres per second. This means that it takes three minutes and 20 seconds for a drop to reach the ground if it falls from a cloud at an altitude of 1800 metres.
- The record for rainfall in one day in Sweden is 276 mm, measured in the Falufjället mountains in Dalarna on 31 August 1997.
- Guadeloupe in the Caribbean holds the world record for rainfall ? 38 mm in one minute on 26 November 1970.
- The world?s rainiest place on average is Cherrapunji in north-eastern India, which gets 11 metres of rain a year.
- Frozen water has been found on the moon.
- A jellyfish?s body has a higher percentage of water than the water it swims in.
- Only 1% of all available water on the Earth is freshwater.
- If you could stack the molecules in a litre of water on top of each other, it would take 8.4 months for light to reach from the bottom to the top of the pile. From the sun to the earth takes 8 minutes.
- Water itself has no taste; it is the salts and minerals in it that give it flavour.
- The amount of water on the Earth is constant ? it never increases or decreases. This means that the water we drink today is the same water the dinosaurs drank 200 million years ago.
