Which of the following is not a factor in measuring latitude?

The correct answer highlights a key concept in geography and navigation. Latitude is a measurement that indicates how far north or south a point is from the equator, which is designated as 0 degrees latitude. Therefore, the north/south position and the distance from the equator are direct measures of latitude.

On the other hand, the prime meridian is a reference line for measuring longitude, not latitude. The prime meridian is located at 0 degrees longitude, running from the North Pole to the South Pole and serving as the basis for determining how far east or west a location is. Since the prime meridian does not provide any information about a location's position north or south of the equator, it is not relevant to measuring latitude.

Angles of divergence relate to the concept of geometry or the spread of lines, but they do not directly measure latitude. Thus, only the distance from the prime meridian is unrelated to latitude measurements, making it the correct choice in this question.
