If the polar axis of Earth moves through a full circle in 26,000 years as a result of precession (see Figure 1-22a), how long will it take for the line between the center of the circle and the spin axis to move through 180° (i.e., to the other side of the circle)?
A) 26,000 years
B) 1 year
C) about 100 years
D) 13,000 years
