The Sun stays above the horizon for 24 continuous hours at least once per year; this is also true within the Arctic Circle, the Antarctic Circle's counterpart in the Northern Hemisphere.
These are IMAGINARY LINES known as the FIVE CIRCLES OF LATITUDE:
Arctic Circle (66°33′50.9″ N)
Tropic of Cancer (23°26′09.1″ N)
Equator (0° latitude)
Tropic of Capricorn (23°26′09.1″ S)
Antarctic Circle (66°33′50.9″ S)
The "tropics" are where the noontime sun can be directly overhead at some time in the year.
The imaginary lines just tell you what the sun does in that location.
wow now thats very interesting.
were they meaning circle as in an island with rounded perimeter or a circle that encopasses every other continent?
