Final answer:
The change that will occur by several minutes of arc each year at most locations is the precession of the Earth's axis.
Step-by-step explanation:
The change that will occur by several minutes of arc each year at most locations is the precession of the Earth's axis. Precession is a wobbling motion of the Earth's axis that takes nearly 26,000 years to complete. This wobbling changes the orientation of the Earth's axis and affects the timing of the seasons.
