Key Differences

Lines of Longitude are imaginary vertical lines that run north to south across the Earth, converging at the poles. Lines of Latitude, on the other hand, are imaginary horizontal lines that circle the Earth parallel to the equator, running east to west.

The prime meridian, located at 0 degrees, is the reference point for Lines of Longitude, and these lines are numbered in degrees east or west of this line. Conversely, the equator is the reference for Lines of Latitude, marked as 0 degrees, with lines numbered in degrees north or south up to 90 degrees at the poles.

Lines of Longitude are used to determine time zones around the world, with time changing by one hour for every 15 degrees of longitude. In contrast, Lines of Latitude do not affect time but are used to indicate climatic zones and can impact the weather and climate of a region.

Each degree of Longitude varies in size, becoming narrower as one travels towards the poles due to the spherical shape of the Earth. However, each degree of Latitude remains relatively consistent, about 69 miles apart, due to their parallel nature.
