A parallel or "line" of latitude is the collection of all points on earth that have
the same single latitude. It circles the earth in an east/west direction, parallel
to the equator, and cuts across all longitudes.
A meridian or "line" of longitude is the collection of all points on earth that have
the same single longitude. It joins the north and south poles, and cuts across all
parallels of latitude.

Each 'meridian' is a line of constant longitude.
The 'latitude' of a location is its angle north or south of the equator. The 'longitude' of a location is its angle east or west of the Prime Meridian.
Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.

Latitude and longitude
The lines that intercept latitude lines are lines of longitude.
Longitude lines go vertically and latitude lines go horizontally.
Every parallel of latitude crosses every meridian of longitude.
Lines of latitude and longitude allows any position on the Earth to be plotted.
