Explanation:
1. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
2. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
3. It only takes 23 hours, 56 minutes and 4.0916 seconds for the Earth to turn once its axis.
4. India lies in the Northern hemisphere, with the mainland extending between latitudes 8°4'N and 37°6'N and longitudes 68°7'E and 97°25'E.
5. Sun rays do not fall perpendicular on all areas of the earth because the earth is round. The sun is placed far away so the light rays projecting from the sun tend to reach the earth in almost parallel .
