Answer #1

The Arctic and Antarctic Circlesare located at ±66.5 degrees latitude. Note that 66.5 + 23.5 equals 90 degrees. This means that on June 21, when theSun is directly over the Tropic of Capricorn at noon, it will not bevisible from the Arctic Circle.

C) At southern hemisphere midsummer (the winter solstice, December 21), the sun would be directly overhead (90 degrees from all horizon directions; the zenith) at noon as seen from a latitute of 23.5 degrees south (Tropic of Capricorn).
