Question

why do we need parallels and meridians

Answer 1

Answer:

To measure degrees of latitude north and south of the equator

Explanation:

Latitude and Longitude (Meridians and Parallels) The Equator is an imaginary circle equidistant from the poles of the Earth. Circles parallel to the Equator (lines running east and west) are parallels of latitude. They are used to measure degrees of latitude north or south of the Equator.
