Equator vs prime meridian

The equator is an imaginary line that runs around the middle of the earth dividing it into the Northern and Southern hemispheres. Every point on the equator is equidistant from the North Pole and the South Pole. The word equator may also be used to describe a line running around the middle of an object, dividing it into to equal sections. The equator is 0 degrees latitude.

The prime meridian is an imaginary line that runs between the North Pole and the South Pole dividing the earth into the Eastern and Western hemispheres. The prime meridian passes through Greenwich, England, and is designated as 0 degrees longitude.
