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.
A glacier doesnât melt slowly and steadily like an ice cube on a table. Once glacial ice begins to break down, the interaction of meltwater and sea water with the glacierâs structure can cause increasingly fast melting and retreat. Today, Earthâs surface is made up of 71% water, 10% ice and 19% land. Most of the worldâs ice is in the Arctic and Antarctic, but some of it is scattered around Earth in the form of mountain glaciers.
