globe with meridians → 带子午线的地球仪

In English geography technology vocabulary class, we learned the phrase "globe with meridians" and knew that it refers to a globe with a meridian.

In geography class, the teacher used this globe to explain the concept of longitude and introduced the meaning of "meridian", that is, the meridian, in English.

The foreign language teacher asked: "In English, what is the English expression of the prime meridian?" What is its longitude? This is the core test point of geography English.
