Because the meridians are not parallel. They're the slices you make when
you want to cut an orange into sections, where each slice goes through the
same point on top and the same point on the bottom, and the pieces taper,
from wide at the skin to nothing at the middle.
The parallels are literally parallel. They're the slices you make when you
want to cut the orange into "rounds", where the slices are all parallel, and
the pieces are all circular disks of different sizes.
It is because all lines of longitude originate and converge there.
Between the equator and either pole, no matter what interval you choose foryour display of the meridians of longitude, they all gradually converge, untilthey all meet in a single point at the pole. The space between any two meridians,at any latitude, is(the space between them at the equator) x (cosine of the latitude). But their behavior on both sides of the equator is perfectly symmetrical.That is, as you move farther from the equator, the meridians converge inthe southern hemisphere exactly as they do in the northern one.
-- Parallels are associated with latitudes. Meridians are associated with longitudes. -- Parallels are parallel, and no tweo parallels intersect. All meridians intersect all other meridians, at two places. -- Every point on a parallel has the same latitude. Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length. Every meridian on Earth has the same length. -- Every parallel is a full circle. Every meridian is a semi-circle. -- Every parallel crosses all longitudes. Every meridian crosses all latitudes. -- The distance between two parallels is the same at every longitude. The distance between two meridians depends on the latitude where it's measured. -- To cross all parallels, you only have to travel 12,000 miles. To cross all meridians, you have to travel 24,000 miles.
The lines running between the two poles are called meridians. These meridians are used in geographic coordinate systems to measure longitude and determine the angular distance east or west of the Prime Meridian (0 degrees longitude).
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
the minimium distance between the two meridians is at the poles because all the meridians comerge at the poles
degrees
That is usually measured in degrees.
No but parallel lines have a constant distance between them
Meridians of constant longitude.

Assuming the Earth's circumference is 40,075.017 km at the equator, and considering there are 360 meridians which results in 360 meridional regions; 40,075.017/360= ~ 111.32 km = 69.171 miles
because the north pole is 90 degrees latitude
The center of Africa is between the Indian and Atlantic meridians.
"Lines" of constant longitude are "meridians".
