Question

Quizplus · Accepted Answer

As an observer moves northward from the equator, the angle with the horizon made by stars as they rise and set decreases from 90 degrees to zero. This is because at the equator, stars rise and set perpendicularly to the horizon, making a 90-degree angle. As one moves towards the poles, this angle decreases, with stars appearing to skim closer to the horizon.
