21 Facts about Water That'll Blow Your Mind
Apr 13, 2017
Water is one of the abundant resources spread across Earth. It’s also one of the most intriguing. Comprising of certain anomalous and unique features that make it one of the most important resources to sustain life, water seldom gets the value it deserves.
What percentage of water is available to humans?
Although it may seem that water is an unending resource, which it actually is, the potable and usable amount is less than 1% of the total volume! So basically we have a very limited resource of fresh water which we can actually use for our needs. Contamination of potable water leads to serious health issues, and you would certainly not want it to affect your health. And with the increasing levels of pollutants in potable water, it’s advisable to buy yourself a high-quality water purifier.
There are interesting facts about this resource that you’ll be awestruck! Did you know that our atmosphere contains more water than the volume contained in all the rivers combined? Strange, but it’s true. Read on to learn more awesome facts about water.
1. The Earth contains roughly around 1.5 billion cubic kilometres of water. That roughly equates to a whopping 800 trillion swimming pools of the standard Olympic size!
2. Almost 97% of the world’s water is undrinkable or salty. The other 2% is locked in glaciers and ice caps. As mentioned earlier, less than 1% is available for our consumption!
3. As a matter of fact, the water on Earth has actually arrived through asteroids and comets – the whole of it! This happened during a phase which has been termed as Late Heavy Bombardment, continuing from 4.5 to 3.8 billion years ago.
4. The Antarctic is presently covered with roughly 10,000 trillion tons of frozen water. It has remained covered with ice for around 30 million years!
5. NASA scientists had discovered a black hole 12 billion light years away from us, which is surrounded by a cloud of water vapour. The cloud contains a mind-boggling 140 trillion times the water that is present in our oceans!
6. Considering the fact all similar molecules such as hydrogen sulphide (H2S) and ammonia (NH3) are gases at room temperature, water should also be a gas. However, its stickiness is what keeps it in the liquid state.
7. Due to this stickiness of the water molecules, water has an inherently high surface tension. This property of water is vital as it helps support life. The surface tension helps water to pull up blood through the vessels against the force of gravity.
8. Ice has around 16 different phases or types, each of which has a unique crystal structure.
9. Believe it or not, but the average human drinks around a thousand litres of water every year! You definitely wouldn’t want to drink that much amount of contaminated water, would you? Invest in a good water purifier and consume fresh clean water.
10. The anomalous expansion of water causes it to expand rather than contract when frozen. This is the sole reason why ice forms at the top while liquid water is found below. This property helps in saving the aquatic life.
11. One of the most mysterious facts about water is that it freezes faster when the conditions are hot! This phenomenon is known as Mpemba effect, and the mystery still hasn’t been unravelled.
12. A human being can stay alive about a month without food, and only about a week without water.
13. The amount of water consumed in producing the coffee beans that give us a cup of coffee is a whopping 200 litres!
14. Liquid water can prove to be a good signal of life. Earth boasts of life wherever there’s a trace of water, even if it’s boiling or extremely acidic.
15. A pint of beer has around 150 litres of water invested in order to produce it!
16. Pure water itself isn’t a conductor of electricity. What makes it a good conductor is a number of impurities that are present in the water.
17. Saturn’s satellite Enceladus is speculated to be the most habitable place for life beyond Earth. Enceladus shoots out jets of water vapour into space – one of the most convincing signals to support life.
18. The Russians, in 1936, had developed a computer that ran on water!
19. If we somehow manage to gather and ball up all the water present on Earth, its radius would be no more than a meagre 700 kilometres.
20. If the Earth had all the water evenly spread on it, then the depth of these water bodies would come to about 3700 metres!
21. The sun produces around a 100 million times the amount of water contained in the Amazon river every second! Just to think that the sun is a medium-sized star!
The second most abundant resource on Earth does have its own share of mysterious and intriguing facts. Climate change and global warming affect the water bodies across the globe. We need to save water and educate the future generation about the importance of water conservation.
