Which one of the following is true about seasonsGroup of answer choicesThey are caused because of of rotationThey are caused because of of revolutionThey have nothing to do with motion of the EarthAllNone of the above

To determine which statement about seasons is true, let's analyze each option step by step:

1. They are caused because of rotation:

   • The Earth's rotation refers to its spinning on its axis, which results in day and night. This rotation occurs approximately every 24 hours. However, this rotation does not cause the seasons.

2. They are caused because of revolution:

   • The Earth's revolution refers to its orbit around the Sun, which takes about 365.25 days to complete. The tilt of the Earth's axis (approximately 23.5 degrees) combined with its revolution around the Sun causes the different seasons. As the Earth orbits the Sun, different parts of the Earth receive varying amounts of sunlight at different times of the year, leading to seasonal changes.

3. They have nothing to do with motion of the Earth:

   • This statement is incorrect because the motion of the Earth, specifically its revolution around the Sun and the axial tilt, is directly responsible for the changing seasons.

4. All:

   • This option suggests that all the previous statements are true, which is not the case.

5. None of the above:

   • This option suggests that none of the previous statements are true, which is also incorrect because the second statement is true.

Based on the analysis, the correct answer is:

They are caused because of revolution
