Etymology: Latin "aequator" (the equalizer, from "aequare," to make equal) gave English "equator," and "aequatorialis" is the adjective built on it, meaning "of the equator." The Latin noun was itself a translation-style coinage: "circulus aequator," the circle that "equalizes" day and night, since at the equator the sun spends roughly equal time above and below the horizon throughout the year. English took the adjective "equatorial" as a scientific term for the line and things lying on or near it, and the modern sense of the equatorial zone with its heat, rainfall and dense vegetation developed from that geographic base. The pattern is ordinary: a Latin adjective ending in "-alis" joined the vocabulary of astronomy and geography, then broadened into descriptive use.
