Another name for lines of latitude are parallels, because the lines are parallel with the equator. Latitude lines run east to west or left to right on a globe or a map.
When giving directional coordinates, especially when globes or maps are concerned, latitude and longitude are often used. If you look at a map or a globe, you will see lines that run up and down and left to right. These lines are not actual lines on the earth, but are used to help find places around the world.
The lines that run north and south are called longitude lines. The lines that run east to west are called latitude or parallel lines. When giving coordinates, the degrees of both the latitude and longitude lines are given so a person can locate a specific location.
