All of them do.
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
All of them
Longitude at the poles is irrelevant. All of the meridians meet at the poles.
All meridians of longitude converge (meet) at the north and south poles.
All meridians of longitude converge at the north and south poles.
Those are "meridians of longitude".
All meridians of longitude converge at the north and south poles.
All meridians of longitude converge at the north and south poles.
All meridians of longitude on the glob meet at the north and south poles.
Meridians - or lines of longitude.
The lines that meet at the North and South Poles are called meridians of longitude. These lines run from the North Pole to the South Pole and are used to measure how far east or west a location is from the Prime Meridian.
The South Pole is at 90 degrees S latitude. The North Pole is at 90 degrees N latitude. All lines of longitude converge at both poles. Also, the Prime Meridian and the International Date Line meet at the poles.
