Question 1552Navigation General
70% to passThe precession of the equinoxes occurs in a(n) _______________.
A
southerly direction
B
westerly direction
C
easterly direction
D
northerly direction
AI Explanation
The correct answer is B) westerly direction. The precession of the equinoxes is the slow westward drift of the equinoctial points along the ecliptic, caused by the gravitational forces of the Sun and Moon acting on the Earth's oblate spheroid shape. This results in a gradual shift of the celestial poles and equator over time, with the equinoctial points (the points where the Sun's apparent path crosses the celestial equator) moving in a westerly direction. The other options are incorrect because the precession does not occur in a southerly, easterly, or northerly direction - it is a westerly motion of the equinoctial points.
