How much water does the Earth contain?

Answer 1

#1379*10^6# #km^3# total water exists in the World.

Oceans contain 97% of the total water (#1379*10^6# #km^3#). Freshwater lakes, rivers, and creeks account for just 0.0072% (#93*10^3# #km^3#).
If you accept total volume of the Earth as #1.098*10^12# #km^3#, you can reach this conclusion: (in terms of volumetric ratio water occupies #1.256*10^-3# of the Earth.
In terms of mass (the mass of the Earth is #5.97*10^24# #kg#), water contributes (#(1379*10^18)/(5.97*10^24)#) only #2.31*10^-4# or 0.0231 percent (mass ratio).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
