| Summary: | With the tsunami tragedy still fresh in our minds, perhaps many would be curious to know how much water
there is on Earth.
According to the National Geographic (Sept, 2002), if the Earth crust is smothered, the entire surface of the
planet would be covered by 2682.24 metres of seawater.
Put it another way, if all the seawater is evaporated, the Earth would be covered with more than 12.192 metres
of salt.
If so, it looks like there is enough water to go around, only that seawater is virtually not "usable".
Ironically though, when it comes to "usable" water, the amount is no more that three per cent that of the seas
and oceans. |
