Q6 (IAS/1994) Geography › World Physical Geography › Solar system bodies Answer Verified

The length of its day and the tilt of its axis are almost identical to those of the earth’. This is true of

Result
Your answer: —  ·  Correct: D
Explanation

Mars is the correct choice. Mars has a rotation period of about 1.03 Earth days (approximately 24.6 hours) and an axial tilt of 25.19°, which is very close to Earth’s 23.5°; these similarities make the length of its day and the tilt of its axis almost identical to those of Earth [1]. As a result, Mars exhibits day–night cycles and seasonal changes that are comparable in character to Earth’s (though a Martian year is about twice as long and its atmosphere is much thinner) [1]. Therefore the statement in the question accurately describes Mars [1].
