Question

lines of longitude are numbered in the same way as _______. options: tropics, equators, parallels, circles

Explanation:

Longitude lines (meridians) and parallels (lines of latitude) are both used to measure positions on Earth. Longitude is measured in degrees east or west, and latitude (parallels) is measured in degrees north or south. Tropics are specific latitude lines, equators is incorrect (there's one Equator), and circles is too vague. So parallels are numbered similarly to longitude lines in terms of angular measurement.

Answer:

Parallels (the option labeled "Parallels" among the choices)
