Single correct option

Consider the following statements:
1. The change of seasons is caused by the revolution of the earth together with the tilt of its axis.
2. The occurrence of day and night is caused by the revolution of the earth.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (A) 1 only

Because the earth's axis is tilted by 23.5 degrees and stays pointed in the same direction as it goes around the Sun, different hemispheres receive different amounts of sunlight in the year, giving seasons. Day and night are due to the rotation of the earth on its axis, not its revolution, so statement 2 is wrong.
