Question

Quizplus · Accepted Answer

Seasonal variations on Mars are due to both its axis tilt and its changing distance from the Sun. Mars has a similar axial tilt as Earth, which causes it to experience different seasons as it orbits around the Sun. Additionally, Mars' elliptical orbit causes it to be closer or further away from the Sun at different points in its orbit, further contributing to seasonal variations.
