Question

Quizplus · Accepted Answer

When the sun is low on the horizon, its light must pass through more of the Earth's atmosphere before reaching an observer, causing longer atmospheric path lengths. This is why sunsets and sunrises often have more vibrant colors, as the light has to travel through more atmospheric particles which scatter the light and create the color effects.
