Quizplus · Accepted Answer

Precession refers to the gradual shifting of the orientation of Earth's rotational axis in a circular motion over a period of about 26,000 years. This causes changes in the apparent positions of stars and affects the timing of the seasons. Eccentricity refers to the shape of Earth's orbit, obliquity refers to the angle of Earth's rotational axis relative to its plane of orbit, tilt refers to the angle of Earth's rotational axis relative to a perpendicular line to its plane of orbit, and orbit refers to the path Earth takes around the sun.
