Final answer:
The Equator is the imaginary line that divides the Earth into the Northern and Southern Hemispheres, and it is located halfway between the geographic North and South Poles.
Step-by-step explanation:
The Equator marks the middle location on the Earth's surface, halfway between the geographic North and South Poles. The Earth has two geographic poles, the points where the line of the Earth's axis of rotation meets the surface. Similar to the geographic poles, there are points in the sky called the north celestial pole and the south celestial pole. The celestial equator is a great circle on the celestial sphere that is in the same plane as Earth's equator and it lies halfway between the celestial poles, just as Earth's equator lies halfway between our planet's poles. This same principle applies to the geographic equator, which is an imaginary line encircling the Earth, equidistant from the poles, and dividing the Earth into the Northern and Southern Hemispheres.
