The word 'arctic' is used to describe a very cold region in the Northern Hemisphere, primarily around the North Pole. It is also used to describe weather conditions, animals, and plants that can survive in such cold environments. The term 'Arctic Circle' refers to a line of latitude north of which the sun does not set during the summer solstice and does not rise during the winter solstice. The word 'arctic' can also be used metaphorically to describe anything that is extremely cold or harsh.
