Question

Greenwhich meridian line passes through which cities

Answer 1

greenwhich meredian passes through Greenwich, a borough of London, and terminates at the North and South poles...hope it help.:)

Answer 2

Greenwich is itself a city and since the Prime meridian passes through this town, it's also referred to as the Greenwich Mean Line.

Since Greenwich is the benchmark, there aren't any notable cities that lie exactly on the GMT. However if you give a leeway of about 1 degree east and west, some notable cities that lie in this margin are London, Brighton, Cambridge(England), Lome(Capital of Togo), Accra(Capital of Senegal), Valencia(Spain) and Bordeaux(France).
