Explain the differences between Parallels and Meridians.

Parallels: The north or south angular distance of a place from the equator is called latitude. Lines drawn an east-west parallel to the equator are called latitudes. There is 90° latitude north of the equator and 90° latitude south of the equator. These distance of 90° latitude is points only called north pole and south pole.

The network of Parallels and Meridians

The links joining north pole and south pole are called meridians of longitude. The meridian passing through Greenwich is known as Prime Meridian. There are 180 meridians towards the east and west of the prime meridian. Thus, there are 360 meridians in all.
