This article is about polar ice caps in general, for Earth's ice cap see:
Polar ice packs A polar ice cap or polar ice sheet is a high-
latitude region of a
planet or
moon that is covered in
ice. There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land; only that it must be a body of solid phase matter in the
polar region. This causes the term 'polar ice cap' to be somewhat of a misnomer, as the term
ice cap itself is applied with greater scrutiny as such bodies must be found over land, and possess a surface area of less than 50,000 km²: larger bodies are referred to as
ice sheets.
