The primary cause of Earth's seasons is the

• constant tilt of Earthn's rotational axis with respect to the plane of its orbit around the Sun

• changing distance of Earth from the Sun at different times of the year

• periodic wobbling of Earth on its axis of rotation

• changing relative positions of Earth, its Moon, and the Sun

• periodic changes in solar energy output
