Where is all the water on earth located?
The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of all the freshwater, almost 70% resides in solid form as it is frozen in ice caps and glaciers, 30% is underground, and less than 1% is located in surface water such as lakes, rivers, and swamps. If you think about it, that's only about one percent of the water on the Earth’s surface, that is easily accessible by humans, and 99% is situated underground.
