Every line of constant longitude joins the north and south poles.

Therefore the length of every line of constant longitude is one half of the earth's polar circumference.

Why all longitudes have the same length?

All longitudes are measured as arcs of great circles that extend from the North Pole to the South Pole, making them equal in length. Unlike lines of latitude, which vary in distance between them as they approach the poles, longitudes maintain a consistent length of about 69 miles (111 kilometers) apart at the equator, converging at the poles. This uniformity is due to the Earth’s spherical shape, where each longitude represents a division of the globe into equal segments.


Why length of longitudes the same?

The length of longitudes is considered to be the same because all longitudes meet at the poles and form complete circles around the Earth. Each longitude line represents an imaginary half-circle that extends from one pole to the other, dividing the Earth horizontally into equal sections. This design ensures that each longitude line is the same length when measured on a globe or map.


Why are the lines of longitudes equal?

Lines of longitude converge at the poles. They are all great circles that intersect at the North and South Poles and are equidistant from each other. This convergence creates lines of longitude that are all equal in length.

Are longitudes same length?

Every meridian of constant longitude joins the Earth's north and south poles, so the length of each meridian is 1/2 of the Earth's polar circumference.

Which map is an equal area projection where latitudes are represented by parallel lines but longitudes are represented by ellipses?

The map you are referring to is likely the Mollweide projection. It is an equal-area projection that represents latitudes as straight parallel lines and longitudes as elliptical arcs. This projection aims to minimize distortion in terms of area, but distorts shapes and distances.
