Definition: The word "antarctic" comes from Greek roots meaning "cold region." It originally referred to areas near the poles, which are typically located in the northern hemisphere; however, it has since been used in many other regions and countries. The specific location or geographical feature is often described by the term "arctic," "boreal," or "frozen." In English usage, it can refer to any area that lies within a 30-degree longitude line north of the Arctic Circle (68°W) but outside the Antarctic Circumpolar Zone (52°S).
