By: ET OnlineSince 1993, we have been celebrating World Water Day on March 22 to raise awareness and accelerate change to solve water crisis problems in the world. So on this day, here are eight interesting facts about water.
Sure, many of us let the faucet run when we are washing our face or brushing our teeth. But a small drip from a faucet can mean losing close to 75 litres of water just in a day.
Wondered why solids sink in water but ice floats? It's because ice is a lot dense and up to 9 per cent lighter than water. It's also a great thing that ice doesn't sink because if ice could sink, it would freeze the whole ocean.
Our bodies are made of 60-70 per cent of just water, while our brain is 75 per cent water. Water plays a crucial role in just about everything!
Our body can survive about a month without food, but we can only live for about a week without water, that's how much our life depends on water.
There are two kinds of water, saltwater and freshwater. While salt water contains large amounts of salt, fresh water has dissolved salt with less than 1 per cent of concentration. Only fresh water is consumable.
Water is made of two crucial elements: Hydrogen and Oxygen. Remember the formula we learnt as kids? 2 Hydrogen 1 Oxygen makes H20.
Apart from regulating the earth, water also helps regulate the human body from carrying nutrients and oxygen to cells to protecting organs and removing wastes, water does it all.
Most of the water found on the earth's surface is permanently frozen and salty, with less than 1 per cent of water supply that is actually drinkable. Close to 97 per cent of water in the world is salty or just undrinkable, while 2 per cent is locked in ice caps and glaciers.
