I do not mean to make it seem I an unappreciative for the help but can you look over my question again. Is Mexico City north or south of the Tropic of Capricorn? My answer I really do think was correct. I said Mexico City is north. On my map the Tropic of Cancer is south, RIGHT?

Thank you for questioning my answer, Reed.

You are right, and I was wrong. My brain cells must have been scrambled. <g>

Mexico City is north of the Tropic of Capricorn.

Apologies for any confusion. Let's clarify the geography. The Tropic of Cancer is indeed located to the north of Mexico City, not the Tropic of Capricorn. Therefore, your answer is correct - Mexico City is north of the Tropic of Capricorn. The Tropic of Cancer is an imaginary line located approximately at 23.5 degrees north of the Equator, while the Tropic of Capricorn is located around 23.5 degrees south of the Equator. If you have a map that shows the Tropic of Cancer to the south, it may be displaying the orientation differently, but in standard cartography, the Tropic of Cancer is positioned to the north.
