Is there a connection between the earths tilt and the tropics of Capricorn and Cancer?

Answer 1

Yes, the tropics are the locations where the sun goes the most north and south. Above the tropics will never see the sun directly overhead.

Answer 2

Yes, the Earth's tilt is responsible for the existence of the Tropics of Cancer and Capricorn. These lines mark the farthest points north and south where the sun appears directly overhead at least once a year, which is influenced by the tilt of the Earth's axis in relation to its orbit around the sun.
