Q. With respect to equinoxes and solstices, consider the following statements:
  1. They occur because the Earth’s axis of spin lies at an angle of 23.5 degrees.
  2. During summer solstice, the Sun is directly overhead at the Tropic of Capricorn.
  3. During the winter solstice, the Sun is directly overhead at the Tropic of Cancer
Which of the statements given above is/are correct?

Answer: Only 1
Notes: The solstices and equinoxes are determined by Earth's orbit and axial tilt of 23.5 degrees. The June solstice occurs around June 20-21, with the north pole tilted toward the Sun, resulting in 24-hour daylight in the Arctic and the longest daylight hours in the northern hemisphere. Conversely, the December solstice occurs around December 21-22, with the south pole tilted toward the Sun, leading to the longest daylight hours in the southern hemisphere. Equinoxes occur around March 21 and September 21, when neither pole is tilted toward the Sun, resulting in equal day and night (12 hours each) worldwide, with the Sun directly overhead at the Equator.
