8 Things You May Not Know About Water
In school, you might have been taught that water makes up about 71% of the Earth, and makes up around 60% of an adult human body. But did you know that only 1% of potable water is easily accessible? This list puts the spotlight on our precious life source and important facts about water access that you may not already know.
70% of freshwater is frozen
The Earth’s ice sheets– Antarctica and Greenland-contain 70% of the world’s freshwater! As mentioned above, that makes the amount of accessible water just 1%, with saltwater not useable for hydration (fun fact: our kidneys can only produce urine that is less salty than saltwater).
Water’s fascinating properties
It is the only substance that can be found naturally on earth in all three forms: liquid, gas and solid! Water in its gas form (water vapor) must not be confused with water gas, the latter being a toxic mixture of carbon monoxide and hydrogen.
Wonders of our “Universal Solvent”
What does its label as “the universal solvent” mean again? That pertains to how water dissolves more substances than any other substance does. Technically, though, the true universal solvent would be Alkahest, a hypothetical substance that could dissolve any other substance (including gold). But with water being the most effective KNOWN solvent, it is important in how it carries all the nutrients and minerals in everything it goes through.
Earth’s water is rare
While water is generally common in the universe according to NASA, most of it is in ice form–like in Jupiter’s moons Ganymede, Europa and Callisto, and Saturn’s Enceladus and Titan. In liquid form, only Earth is confirmed to have it, so far. This makes our water more precious because of all the carbon-based life that depends on it (including ours).
