The equator itself is a 'line' of latitude. All others are parallel to it,
and to each other. They don't run either way. They just stay put.
They intersect other things, but they don't run over anything.
Lines that run parallel to the equator are called latitude lines or parallels.
Lines of latitude circle the earth, parallel to the equator.
Lines of latitude run parallel to the Equator (which is zero latitude).
You have answered the question for yourself ; They are 'Latitudes''. Longitudes (Meridians) are lines that run North to South from the North Pole to the South Pole. Longitudes come to a point at the poles, but spread out to a maximum at the Equator.
Latitude lines run from east to west, parallel to the equator. Longitudinal lines are perpendicular to latitude lines and run north to south.
Lines of latitude.
Latitude lines run parallel to the equator.
Lines of Latitude encircle the Earth, running parallel to the Equator.
Lines of Latitude run horizontally round the World and parallel to the Equator.
Latitude lines run east-west, but measure north and south. Longitude lines run north-south, but measure east and west.
Lines of latitude are imaginary lines that run parallel to the equator and form part of a grid used to describe where on the earth you are. They are often called parallels.
lines of latitude run from east to west. the most common example is the equator
