AI overview

Longitude refers to the lines running from pole to pole on Earth that help establish a geographic coordinate system for locating positions on the planet's surface. These lines of constant longitude, called meridians, work together with lines of latitude to create a grid that allows us to specify the exact location of any point on Earth.
