What are the parallel lines on a map called?

Answer 1

on a world map - the curved parallel lines are lines of latitude and longitude. They geographic co-ordinates. These coordinates values are measured in degrees, and represent angular distances calculated from the center of the EarthThese coordinates values are measured in degrees, and represent angular distances calculated from the center of the Earth. EAST TO WEST/WEST TO EAST - lines of latitude All lines of latitude are parallel to the Equator, and they are sometimes also referred to as parallels. Parallels are equally spaced. There are 90 degrees of latitude going north from the Equator, and the North Pole is at 90 degrees N. There are 90 degrees to the south of the Equator, and the South Pole is at 90 degrees S NORTH TO SOUTH/SOUTH TO NORTH - lines of longitude There is no obvious 0-degree point for longitude, as there is for latitude. Throughout history many different starting points have been used to measure longitude. By international agreement, the meridian line through Greenwich, England, is currently given the value of 0 degrees of longitude; this meridian is referred to as the Prime Meridian. Longitude values are indicate the angular distance between the Prime Meridian and points east or west of it on the surface of the Earth.
