Question

Reflection of the sunlight from the upper layers of the Earth's atmosphere causes

• A. days and nights
• B. tides
• C. eclipses
• D. twilight

Answer 1

The correct option is D twilight

You can define twilight simply as the time of day between daylight and darkness, whether that’s after sunset, or before sunrise. It’s a time when the light from the sky appears diffused and often pinkish. The sun is below the horizon, but its rays are scattered by Earth’s atmosphere to create the colors of twilight.

We have twilight because Earth has an atmosphere. Some light scatters through small particles in the atmosphere – so there’s still some light in the sky even after the sun has gone down.
