Question

From the western most point to the eastern most point the local times of india extend over a time difference of ---- ?
(A) No difference
(B) 30 minutes
(C) 1 hour
(D) Over 1 hour

Answer 1

Hint - The time difference between western point and eastern point is just under two hours, so the sun rises and sets much earlier on the eastern side than the western side. India's time meridian passes through Allahabad in Uttar Pradesh, which is about half between the country's both points.

Complete answer: If the earth were not bent on its axis, it would be equal day and night everywhere. Similarly, if the Earth did not revolve around the Sun, then in one hemisphere the days would always be large and the nights small, while in the other hemisphere the nights would be big and the days small. But except the equatorial part, there is a difference in the length of day and night in different seasons in all other parts of the world. Day and night are always equal on the equator because the light circle always divides it into two equal parts. So the equator One half receives light at each position.
The Northern Hemisphere receives sunlight for 12 hours or more in the period from 21 March to 23 September. So here the days are big and the nights are small. As we move towards the North Pole, the duration of the day also increases. At the North Pole, the duration of the day is six months. Sunlight is received in the southern hemisphere for 12 hours or more from 23 September to 21 March. Like the South Pole As we move, the duration of the day also increases. For this reason, the day remains for six months at the South Pole. In this way, both the North Pole and the South Pole stay for six months day and night for six months.
The Earth rotates not only on its axis but also revolves around the Sun. Therefore, the relative positions of the Earth from the Sun keep changing. There are four main stages in the rotation of the Earth and there are seasonal changes in these states.

So option D is the correct answer.

Note - The earth always rotates on its axis like a loop from west to east, which is called 'rotation or rotation of the earth'. Due to this there are days and nights. Therefore, this speed is also called 'daily speed'. Nakshatra Day.
