The Earth is 70% Water

The factoid that the earth is 70% water is often --if you'll excuse the pun-- floated around, but of course that's only true if you're talking about how much water covers the earth's surface. Here's an image that compares the total volume of water on the earth with the earth's volume itself (the second image compares the earth's atmosphere)

    

There it is, the blood of life, a limited resource, in all its delicate splendor.

You never did answer the question! What percent by mass, and what percent by volume, is the Earth's water composition? The picture illustrates the fact that water constitutes << 70% of the planet's volume, but that's all it does! is to vaguely illustrate it! ^^;
