GEOGRAPHY IN THE NEWS:
The Arctic Circle passes through eight countries* and is the northernmost of the five major circles of latitude (e.g., Equator, Tropic of Capricorn). The precise location of the Arctic Circle varies with the tilt of the earth on its axis but is defined as the southernmost location from which the sun is still visible at midnight at least once a year and from which the sun is not visible at noon at least once a year. This geography imposes unusual conditions, beyond the cold, for life above the Arctic Circle.
