Briefly explain how the length of twilight varies with seasons
The length of twilight depends on season and latitude. During the summer in middle latitudes, twilight adds about 30 minutes of light to each morning and evening. The duration of twilight increases with increasing latitude, especially in the summer. At high latitudes during the summer, morning and evening twilight may converge, producing a white night-a nightlong twilight. At low latitudes, twilight tends to be shorter, with more abrupt transitions between daylight and darkness.
