It's a complete circle.

The parallels are not the same length.

The equator is the longest latitude line.

Indicates east-west direction.

Which latitude line can you run around the earth faster?

The latitude closest to the North Pole.

At the North and South Poles, the latitude circle shrinks to a single point.

Which parallel of latitude takes the longest to circle the Earth?

The equator is the longest latitude.

The equator divides the Earth into northern and southern hemispheres.
