What is the term used for the change of seasons due to the Earth's position?

The correct term for the change of seasons due to the Earth's position is actually related to the concept of revolution. The Earth's revolution around the Sun takes approximately one year and is the primary reason for the seasonal changes we experience. During this revolution, different parts of the Earth receive varying amounts of sunlight at different times of the year due to its axial tilt. This variation in sunlight intensity and duration causes the seasonal shifts, marking the transition from winter to spring, summer to fall, and so on.

In this context, "revolution" refers specifically to the orbital path the Earth takes around the Sun, which is responsible for these seasonal changes. Seasons are not directly caused by the tilt itself, which is constant and essential for the angles of sunlight but is rather a result of how that tilt interacts with the Earth's orbit in its revolution around the Sun.

The other terms—equinox, tilt, and solar cycle—while related to the Earth's dynamics and its position in space, do not directly encapsulate the overall concept of seasonal change resulting from the Earth's movement around the Sun.
