How much water do you
think there are on Earth? Approximately 70% of the surface of the Earth is
covered by water, and oceans contain about 96.5% of all water from the planet.
But there is water in the air as water vapor, in rivers and lakes, ice caps and
glaciers, as moisture in the soil and groundwater, even in your body and your
dog. However, all that water is in the "small" area of 1,385 km in
diameter.
