At which location do the equator and Greenwich prime meridian intersect?

The equator and the Greenwich prime meridian intersect at a specific geographic point known as the intersection of these two significant lines of reference. The correct answer identifies that this intersection occurs in the Gulf of Guinea, which is situated off the west coast of Africa.

This geographical point represents the coordinates 0 degrees latitude (the equator) and 0 degrees longitude (the prime meridian), making it a unique location where the two primary reference lines of the Earth's coordinate system meet. This area is notable for its significance in navigation and mapping, as it serves as a foundational point from which other geographic coordinates are derived.
