Compare and contrast parallel and meridian

A meridian is an imaginary line on the Earth's surface from the North Pole to the South Pole that connects all locations with a given longitude. The position of a point on the meridian is given by the latitude. Each meridian is perpendicular to all circles of latitude at the intersection points. Each is also the same size and is half of a great circle on the Earth's surface.
