A couple of notes:

One addition to your explanation:

a Minute of Longitude distance varies by the cosine of the latitude.

For instance, at the equator a minute of longitude is one NAUTICAL mile.
(since the cosine of the 0 degree latitude = 1)

At the North Pole, a minute of longitude distance is equal to 1nm x the
cosine of the latitude = 1 x cosine of 90 degrees = 0 nm.
