Parallels, which are imaginary dividing lines drawing parallel to tje equator and perpendicular to the Earth's axis, measure distances north and south by sectioning the globe into equally spaced circles

The sentence shown in the question above is not correct and presents false information.

This is because the parallels are, in fact, imaginary lines that cross the earth in a horizontal direction. In this case, these lines form circles that divide the earth, however, these circles are not equally spaced, but have larger spaces in the central part of the earth and smaller spaces as it approaches the earth's poles.

The equator line is one of these parallels, as are the tropics of Capricorn and Cancer.

Parallels are measured in degrees of latitude between the equator and any other parallel.
