How did the tropics get their names?

The term "tropics" comes from the Greek Word "tropikos," which means "turning" or "to turn." This refers to the points where the sun appears to turn back in the sky, marked by the Tropic of Cancer and the Tropic of Capricorn. These latitudes are significant because they delineate the regions where the sun is directly overhead at noon during the solstices, resulting in the characteristic warm climates of the tropics.
