The human physique is about 50 per cent to 60 percent entire body water. Together with survival and hygiene, folks use liquid water for Electricity and transportation.
In essence, it is the most important terrestrial planet, but is more compact and fewer large than any with the gas/ice giants of your Outer photo voltaic System. And by using a imply density of five.514 g/cm³, it's the densest planet in the Solar technique.
