Question

what do we call the two sets of lines that geographers have created to help locate places on a map or globe?​

Answer 1

Answer:

Tropic of Cancer and the Tropic of Capricorn

(And the equator)

Answer 2

These lines are called parallels of latitude and meridians of longitude. Two of these imaginary reference lines, the equator and the prime meridian, are called primary reference lines because they are where we start the numbering system.
