Which line of latitude is located approximately 23 1/2 degrees North of the equator?

The line of latitude located approximately 23 1/2 degrees north of the equator is known as the Tropic of Cancer. This specific latitude marks the northernmost point at which the sun can be directly overhead at noon, which occurs during the summer solstice around June 21 each year.

The Tropic of Cancer is significant in the study of climate and solar illumination because it helps define the tropics, the region of Earth with a generally warm climate characterized by minimal temperature variation throughout the year. The concept of the tropics is fundamental in understanding seasonal changes and weather patterns across different geographical areas.

The other options refer to different lines of latitude: the Tropic of Capricorn is positioned at 23 1/2 degrees south of the equator; the Equator represents 0 degrees latitude, serving as the baseline from which all other lines of latitude are measured; and the Arctic Circle is found at approximately 66 1/2 degrees north, marking the southernmost point where the sun can remain continuously above or below the horizon during the summer and winter solstices. Such distinctions are key in geography, climatology, and navigation.
