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.
Polar ice caps are high-latitude areas completely covered in ice that occur in the polar regions of Earth. Other planets, Mars for example, have polar ice caps also, but unlike Earthâs ice, which is largely composed of frozen water, Marsâ ice is mostly made up of frozen carbon dioxide. Polar areas receive less solar energy from the sun and are therefore subject to low surface temperatures, allowing ice caps to form.
