The sun is visible a little before it rises on the horizon and a little after it sets below the horizon. This is the consequence of the phenomenon of _____? Answer: Atmospheric refraction

This occurs because the Earth's atmosphere bends sunlight as it passes through layers of air with different densities, causing the sun's apparent position in the sky to be higher than its actual position.
