Quizplus · Accepted Answer

The apparent twinkling of stars is caused by the Earth's atmosphere. As light from a star travels through the various layers of the Earth's atmosphere, it is bent and refracted due to temperature and density differences. This causes the star's light to change in intensity and color, creating the twinkling effect.
