Answer 2

Answer:

twilight is the time after dusk but before night. It is the time when is sun is below the horizon but the sky is still visually blue.

Dusk is the time when sun is very near to the horizon and is on the edge of disappearing.

Dawn is also the time when sun is very near to the horizon, but it is rising instead of setting.
