The complete worked solution.
Every step explained - no skipped algebra.
Precession is the slow, conical movement of Earth's rotational axis caused by gravitational forces from the Sun and the Moon. This motion gradually shifts the orientation of Earth’s axis, leading to changes in the timing and position of equinoxes and solstices over a period of approximately 26,000 years. Precession affects celestial coordinates and has long-term climatic implications.
Final Answer: Option A - Shift in the position of equinoxes over time
