Question

t
Latitudes are also called "parallels' because
they are parallel to each other! Simple!
Longitudes are also called 'meridians. We
get meridian from the Latin meridianus
meaning noon, that is when the Sun is
directly overhead (noon) at a given
longitude. So, longtitudes are related to
time.​

Answer 1

Answer:

The lines of longitude run north and south. They are used to define the east-west position of a location on the planet. They run perpendicular to the equator and latitude lines. Half of a longitudinal circle is called a meridian, which is where the term comes from in the name Greenwich Meridian or Prime Meridian.
