Why will the sun never be most directly most vertically most perpendicularly overhead in Chicago (42 n?

Answer 1

The sun will never be directly overhead in Chicago, which is located at approximately 42 degrees north latitude, because the maximum latitude at which the sun can be directly overhead is the Tropic of Cancer at 23.5 degrees north. As the Earth orbits around the sun, the sun's direct rays shift between the Tropic of Cancer and the Tropic of Capricorn (23.5 degrees south). Therefore, at latitudes higher than 23.5 degrees north, such as Chicago, the sun can never reach a position directly overhead.
