A geographical grid is formed by the intersection of lines of latitude and longitude. Lines of latitude are imaginary circles running horizontally around the globe, parallel to the Equator, measuring distance north or south of the Equator (0°). Lines of longitude are imaginary semi-circles running vertically from the North Pole to the South Pole, measuring distance east or west of the Prime Meridian (0°). Therefore, both statements are correct in describing the components of a geographical grid.

A geographical grid is defined by the network of intersecting lines of latitude (east-west) and longitude (north-south), used for pinpointing locations on Earth.

Latitude lines are called parallels, and longitude lines are called meridians. The latitude of the equator is 0°, the North Pole is 90° N, and the South Pole is 90° S. The Prime Meridian is 0°, and longitude is measured up to 180° East or West.
