Question

Change in Seasons occur due to
(A) Earth’s rotation
(B) Earth’s Revolution
(C) Inclination of Earth axis
Choose the correct options from the options given below:

• A. (A) and (B) only
• B. (B) and (C) only
• C. (A) and (C) only
• D. (A), (B) and (C)

Answer 1

The Correct Option is B

The question asks for the factors responsible for the change in seasons on Earth. To analyze and determine the correct answer, let's discuss each option:

1. Earth's Rotation: This refers to the Earth spinning on its axis. It results in the day and night cycle but does not cause seasonal changes.
2. Earth's Revolution: This is the Earth's orbit around the Sun, taking approximately one year to complete a full cycle. The revolution of the Earth contributes to the changes in seasons as different parts of the Earth receive varying amounts of sunlight throughout the year. This is a significant factor in the occurrence of seasons.
3. Inclination of Earth's Axis: The Earth's axis is tilted at an angle of about 23.5 degrees concerning its orbital plane. This tilt, combined with the Earth's revolution around the Sun, leads to variations in the duration and intensity of daylight experienced by different parts of the Earth, thus causing seasons.

Based on the above explanations:

• Earth's rotation is responsible for the day-night cycle but not for the changing seasons.
• Earth's revolution and the inclination of its axis are both responsible for the change in seasons.

Therefore, the correct answer is (B) and (C) only. The change in seasons is primarily a result of Earth's revolution and the inclination of its axis.
