Question

oss.04 which of these best arranges the planets in the solar system in the increasing order of their number of moons?
○ mars → neptune → uranus → saturn
○ uranus → jupiter → neptune → saturn
○ mars → venus → uranus → jupiter
○ earth → saturn → mars → jupiter

Explanation:

1. Recall the number of moons for each planet:

• Mars has 2 moons.
• Neptune has 14 moons.
• Uranus has 27 moons.
• Saturn has 83 moons.
• Venus and Earth have 0 moons.
• Jupiter has 95 moons.

1. Analyze each option:

• Option 1: Mars (2) → Neptune (14) → Uranus (27) → Saturn (83). This follows increasing order of number of moons.
• Option 2: Uranus (27) → Jupiter (95) → Neptune (14) → Saturn (83). Jupiter has more moons than Neptune and Uranus, and Neptune has fewer than Uranus, so this is incorrect.
• Option 3: Mars (2) → Venus (0) → Uranus (27) → Jupiter (95). Venus has 0 moons which is less than Mars' 2, so this is out of order.
• Option 4: Earth (0) → Saturn (83) → Mars (2) → Jupiter (95). Saturn has more moons than Mars and Earth, and Mars has more than Earth but less than Saturn, so this is incorrect.

Answer:

Mars → Neptune → Uranus → Saturn
