Assertion (A): Kiribati redrew its section of the International Date Line so that the line bulges far to the east, close to 150°W.

Reason (R): This was done so that the entire country would fall within the same calendar day for administrative convenience.

Consider the following statements regarding the Earth's axial tilt of 23.5°:

1.It is primarily responsible for seasonal variation in the amount of insolation received on Earth.
2.If the tilt were to increase, the width of the Torrid Zone would decrease.
3.If the tilt became zero, there would be no seasonal variation anywhere on Earth.

Which of the statements given above is correct?

With reference to the special parallels of latitude, consider the following pairs:

3.Antarctic Circle — Experiences

Which of the pairs given above is/are correctly matched?

India follows a single Standard Time based on 82.5°E longitude, passing near Mirzapur. Which of the following is the most appropriate reason for choosing 82.5°E rather than the country's geographic midlongitude?

Consider the following statements about the Earth's revolution around the Sun:

1.The Earth is closest to the Sun (perihelion) in early January and farthest (aphelion) in early July.
2.Because of perihelion in January, the Southern Hemisphere summer is slightly warmer than it would be on a circular orbit.
3.The Earth's orbital speed is greater at aphelion than at perihelion.

Which of the statements given above is/are correct?

A traveller notes that at her location, the Sun is directly overhead at local noon on a given day, and her wristwatch (set to IST) shows 11:30 a.m. at that instant. Assuming no daylight-saving adjustment, which one of the following can be inferred about her approximate longitude?

Sunrise occurs earlier (by clock time) at Dispur (Assam) than at Dwarka (Gujarat), even though both fall within the same Indian Standard Time zone. Which one of the following best explains this?
