Let's consider 3 options for my position on Earth:
- North to tropic of Cancer
- Between tropic of Cancer and Capricorn
- South to tropic of Capricorn
If I take a compass and point it to the Sun, will it match next guess:
- North to tropic of Cancer -> the Sun will alway be to south
- Between tropic of Cancer and Capricorn -> the Sun may be both to north and south
- South to tropic of Capricorn -> the Sun will alway be to north
