Explanation:
Detailed explanation-1: -Atmospheric refraction causes advance sunrise and delayed sunset.
Detailed explanation-2: -Because of atmospheric refraction of light, light appears to come from a higher position above the horizon. Thus sun appears earlier than actual sunrise. Delayed sunset : Same reason, as similar refraction occurs at the sunset.
Detailed explanation-3: -The sun stays in its position at the center of our solar system. It doesn’t rise and set. But it appears to rise and set because of the Earth’s rotation on its axis. It makes one complete turn every 24 hours.
Detailed explanation-4: -Sun rises two minutes before the actual sunrise due to the phenomenon of atmospheric refraction.
