Those lines are called longitude and latitude.
The imaginary lines on the globe helps because it divides the Northern Hemisphere from Southern Hemisphere. Therefore, imaginary lines are helpful.
Latitude
-- Most of the imaginary lines on the surface are parallels of latitude, meridians of longitude, political boundaries, and shipping routes. -- The imaginary lines through the center of the globe are the axis and diameters.

Lines of Latitude
The horizontal lines are called latitudes and the vertical lines are called longitudes.
The Equator is slightly bigger then any of the other imaginary lines.

Latitude lines are the imaginary lines on a globe that are horizontal.
Lines of longitude.
So that we may all agree on and communicate absolute locations on the surface of the globe.
