Question

which phrase describes the prime meridian?
○ runs parallel to the equator
○ is a line of latitude
○ is labeled at 90 degrees on a world map
○ divides the western and eastern hemispheres

Explanation:

The prime meridian is a line of longitude (0° longitude). Lines parallel to the equator and lines of latitude are the same (east-west lines), so the first two options are incorrect. 90 degrees refers to the poles, not the prime meridian. The prime meridian, along with the 180° meridian, splits the globe into Western and Eastern Hemispheres.

Answer:

divides the Western and Eastern Hemispheres
