Regarding solar system planets:
1. All Jovian planets have solid surfaces.
2. Uranus's axis of rotation is nearly parallel to its orbit.
Which of the above is are correct?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer:
Statement 2 only
Explanation:
Statement 1 is incorrect. Jovian planets (Jupiter, Saturn, Uranus, and Neptune) are gas and ice giants composed mainly of hydrogen, helium, and other gases. They do not have a well-defined solid surface.
Statement 2 is correct. Uranus has an extreme axial tilt of about 98°. This unique orientation means it rotates completely on its side relative to the plane of the solar system, making its axis of rotation nearly parallel to its orbital plane.
Key Points:
• Jovian planets have no solid surface
• They are composed mainly of gases and ices
• Uranus has an extreme axial tilt (~98°)
• It is known as a “sideways planet”
Additional Facts:
• Jovian planets are classified into gas giants and ice giants
• Jupiter and Saturn are gas giants
• Uranus and Neptune are ice giants
