Effects on Seasons in Low and High Latitudes
- During sunrise and sunset, the Sun is below the horizon and the light received from the Sun is diffused. The period of diffused sunlight received before the morning is called dawn. Similarly, diffused light of the Sun received just before the sunset is known as dusk or twilight.
- This phenomenon is experienced more in temperate regions.
- In latitudes beyond 50°, the duration of twilight increases. In Polar Regions, twilight lasts for about seven weeks at a stretch.
- This is because twilight is refracted light. The duration of twilight is short at the Equator because the Sun rises and sets in a vertical path. On the other hand, the duration of twilight is longer in the Polar Regions because the region receives slanting rays of the Sun.
