Question

Quizplus · Accepted Answer

Motion parallax is the difference in the apparent speed and direction of objects that are close versus far away as an observer moves. When moving forward, objects that are closer to the observer will appear to move faster in the opposite direction, while objects that are farther away will move more slowly in the same direction. Therefore, choice D is the correct answer.
