What type of lines converge toward the poles on a map?

The correct response identifies that longitude lines, also known as meridians, are the type of lines that converge toward the poles on a map. This convergence occurs because meridians are vertical lines that run between the North and South Poles. As you move away from the equator toward either pole, the distance between these lines decreases, ultimately converging at the poles themselves.

In contrast, latitude lines, which are horizontal and run parallel to the equator, maintain a constant distance from one another. These lines measure how far north or south a location is from the equator and do not converge. The term equatorial lines is not commonly used in mapping; the equator itself is a specific latitude line that divides the Earth into the Northern and Southern Hemispheres but does not denote the convergence of lines.
