Frozen water is found on the Earthâs surface primarily as snow cover, freshwater ice in lakes and rivers, sea ice, glaciers, ice sheets, and frozen ground and permafrost (permanently frozen ground). The residence time of water in each of these cryospheric sub-systems varies widely.
Q. What is the approximate ratio of fresh to salt water on earth? I would guess that the polar ice caps are a large reservoir of fresh water, but much smaller than the salt water in the oceans. A. The amount of fresh water in ice caps and glaciers adds up to considerably more than a drop in the bucket when compared with the salty ocean, but it is still only a glass of water in the bathtub, according to estimates by Dr. David A. Ross, an oceanographer and a scientist emeritus at the Woods Hole Oceanographic Institution in Massachusetts.
