The correct terminology for describing the location of the equator is:

* It is an imaginary circle that divides the Earth into the Northern Hemisphere and the Southern Hemisphere.

Here's a breakdown:

* Imaginary circle: The equator is not a physical line, but a conceptual one.

* Divides the Earth: The equator runs around the Earth, splitting it in half.

* Northern Hemisphere and Southern Hemisphere: The equator separates the Earth into the Northern Hemisphere (north of the equator) and the Southern Hemisphere (south of the equator).

You can also say:

* The equator is located at 0 degrees latitude.

This is because the equator is the starting point for measuring latitude, which is the angular distance north or south of the equator.
