The northern and southern limits of the apparent movement of the sun are marked by the Tropics of Cancer and Capricorn. These are imaginary lines located at 23.5 degrees north and south of the equator, respectively. The Tropic of Cancer marks the northernmost point where the sun appears directly overhead during the summer solstice in the northern hemisphere, while the Tropic of Capricorn marks the southernmost point where the sun appears directly overhead during the summer solstice in the southern hemisphere. These lines also mark the limits of the tropical zone, where the climate is generally hot and humid.
