Question

Quizplus · Accepted Answer

Atmospheric refraction causes light from a star passing through Earth's atmosphere to bend, making the star appear higher in the sky than it actually is when it is near the horizon. Therefore, the correct option is that a star seen near the Earth's horizon is slightly lower than it appears, not higher.
