Total water on the Earth

Total water on the Earth
Here is a nice picture to understand how much water exists on our planet. I have removed the complex details, but you hac view them here



Total water on Earth

The largest sphere represents all of Earth's water, and its diameter is about 860 miles. The sphere includes all the water in the oceans, ice caps, lakes, and rivers, as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.

Liquid fresh water

How much of the total water is fresh water, which people and many other life forms need to survive? The blue sphere over Kentucky represents the world's liquid fresh water (groundwater, lakes, swamp water, and rivers).

Water in lakes and rivers

Do you notice that "tiny" bubble over Atlanta, Georgia? That one represents fresh water in all the lakes and rivers on the planet, and most of the water people and life of earth need every day comes from these surface-water sources







The data used on this page comes from Igor Shiklomanov's estimate of global water distribution.
