Every meridian of constant longitude is nominally a semi-circle, equal in length to
all other meridians, and joining the Earth's north and south poles.
yesYes.
Lines of longitude meet at the poles, both North and South. At the North Pole, all lines of longitude converge and meet at a single point. The same holds true for the South Pole, where lines of longitude also converge and meet at a single point.
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.
meridians or lines of longitude
"Lines" of constant longitude are "meridians".
Lines of longitude, or meridians.
That's true of the Mercator projection, among others.
Lines of longitude appear vertical with varying curvature in this projection, but are actually halves of great ellipses, These lines met at the poles but the distances between these lines are divided into degrees, minutes and seconds. There is no unit expressed as a "pole."
No, this statement is false. Meridians are lines of longitude that converge at the poles, meaning they touch at the poles. Lines of latitude, however, like the equator, never intersect and are always parallel to each other.
Parallel lines, by definition, cannot meet. The lines of longitude meet at the Poles.
Vertical lines parallel to the prime meridian are lines of longitude.
lines of longitude are lines drawn north and south and measure east and west a famous line of longitude is the Prime meridian
