A) only to its changing distance from the Sun
B) only to its axis tilt
C) to changes in the amounts of energy emitted by the Sun
D) both to its axis tilt and its changing distance from the Sun

Question

Quizplus · Accepted Answer

The seasonal variations on Mars are due to both its axis tilt and changing distance from the Sun. Mars has a similar axial tilt to Earth, which means that it experiences similar seasonal variations. However, Mars' orbit is more elliptical than Earth's, which means that it is further away from the Sun during certain parts of its orbit. This causes additional variations in the amount of solar energy that Mars receives, which in turn affects its seasons.
