The rotation of the earth on its own axis and the revolution of earth around the sun cause changes in season and day and night. The change in seasons is caused by the rotational tilt of the earth on its axis when it revolves around the sun.
The earth has an axial tilt of 23.5 degrees which means that its rotation axis is inclined to its orbital axis at an angle of 23.5 degrees. This causes one pole of the earth to be directed more towards the Sun on one side of the orbit, and the other pole on the other side. This is the reason for occurrence of 'seasons' on earth'.
 
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.

Yes because due to revolution of the earth, atmosphere changes which is responsible for changing of seasons and inclination of earth's axis makes an orbital plane in which earth revolves around the sun hence its also changes the season but due to rotation of earth we can see daytime and night and revolution of moon is responsible for rotation of earth.
So option (d) - I,II is correct

Which of the following is responsible for the change of seasonsI. Revo...
Revolution of the Earth, Inclination of the Axis of the Earth, and Rotation of the Earth are responsible for the change of seasons. The correct answer is option 'D' (I, II).

I. Revolution of the Earth:
The revolution of the Earth around the Sun is the primary factor that causes the change of seasons. The Earth takes approximately 365.25 days to complete one revolution around the Sun, resulting in a year. The revolution of the Earth determines the length of a year and the timing of the seasons.

II. Inclination of the Axis of the Earth:
The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbital plane. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year. When a particular hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. On the other hand, when the same hemisphere is tilted away from the Sun, it receives less direct sunlight and experiences winter.

III. Rotation of the Earth:
The rotation of the Earth on its axis also contributes to the change of seasons. The Earth rotates once every 24 hours, causing day and night. As the Earth revolves around the Sun, different parts of the planet receive varying amounts of daylight. During summer, the hemisphere tilted towards the Sun receives more daylight hours, resulting in longer days and shorter nights. In contrast, during winter, the hemisphere tilted away from the Sun receives fewer daylight hours, leading to shorter days and longer nights.

IV. Revolution of the Moon:
The revolution of the Moon around the Earth does not directly influence the change of seasons on Earth. The Moon's revolution affects tides and lunar cycles but does not play a significant role in the Earth's seasons.

In conclusion, the correct factors responsible for the change of seasons are the revolution of the Earth, the inclination of the Earth's axis, and the rotation of the Earth. These factors determine the amount and intensity of sunlight received by different parts of the Earth, leading to the distinct seasons experienced throughout the year.
