प्रश्न
Give a geographical reason for the period of twilight and dawn increases polewards.
Advertisements
उत्तर १
On account of the oblique path of the sun towards poles than the vertical path along the equator, the length of dawn and twilight is greater, as it is nearly one hour near the equator and 50 days at the poles.
उत्तर २
Latitudes go on increasing polewards. In the middle and high altitudes duration of sunlight is limited. Both twilight and dawn continue so long as the sun is 18° below
