Question

drag each label to the correct location on the table. classify each planet as an inner planet or an outer planet. planet a has 67 moons, and major parts of its atmosphere are hydrogen and helium. planet b has rings but not much atmosphere. planet c has no moons but has high volcanic activity. known as the red planet, planet d has high amounts of carbon dioxide in its atmosphere and has two moons. planet e has a thin layer of atmosphere but no moons due to the effects of the sun’s gravity. planet f has 27 moons, and its atmosphere is mostly composed of hydrogen, helium, and methane.

Explanation:

To classify planets as inner or outer, we use the following characteristics: Inner planets (Mercury, Venus, Earth, Mars) are terrestrial (rocky), have few or no moons, thin atmospheres (except Venus), and no rings. Outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants/ice giants, have many moons, thick atmospheres (H, He, or methane), and rings (except Uranus/Neptune have faint rings, Saturn has prominent).

Inner Planets:

• Planet B: Has rings but not much atmosphere? Wait, no—inner planets don’t have rings. Wait, correction: Inner planets (terrestrial) have no rings, few moons, rocky. Let’s re-express:
• Planet C: No moons, high volcanic activity (terrestrial, like Earth/Venus/Mars).
• Planet D: “Red planet” (Mars), CO₂ atmosphere, two moons (Phobos/Deimos) → inner.
• Planet E: Thin atmosphere, no moons (gravity from Sun) → inner (like Mercury/Venus).

Wait, initial error: Planet B has rings—outer planets have rings. Let’s redo:

Inner Planets (Terrestrial: Mercury, Venus, Earth, Mars):

• Rocky, few/no moons, thin atmospheres (or thick CO₂ like Venus/Mars), no rings.
• Planet C: No moons, high volcanic activity (terrestrial).
• Planet D: Red planet (Mars), CO₂, two moons → inner.
• Planet E: Thin atmosphere, no moons (Mercury/Venus-like) → inner.
• Planet B: “Has rings but not much atmosphere”—wait, inner planets don’t have rings. Maybe a typo? If “has rings but not much atmosphere” is incorrect, but assuming: Inner planets have no rings, so Planet B might be mislabeled, but likely: Inner planets are C, D, E (and maybe B? No—rings are outer). Wait, outer planets:

Outer Planets (Gas/Ice Giants: Jupiter, Saturn, Uranus, Neptune):

• Many moons, thick atmospheres (H, He, methane), rings.
• Planet A: 67 moons, H/He atmosphere → outer (Jupiter/Saturn-like).
• Planet F: 27 moons, H/He/methane → outer (Uranus/Neptune-like).
• Planet B: Has rings (outer planets have rings) → outer (Saturn has rings, but “not much atmosphere” is odd—maybe Saturn’s atmosphere is thick, but maybe a simplification).

So correct classification:

• Inner Planets: Planet C, Planet D, Planet E (and maybe Planet B? No—rings are outer. Wait, recheck:

Inner planets (Mercury, Venus, Earth, Mars):

• Mercury: no moons, thin atmosphere.
• Venus: no moons, thick CO₂.
• Earth: 1 moon, thick N/O.
• Mars: 2 moons, thin CO₂, “red planet.”

Outer planets (Jupiter, Saturn, Uranus, Neptune):

• Jupiter: 95+ moons, H/He.
• Saturn: 146+ moons, H/He, rings.
• Uranus: 27 moons, H/He/methane, rings.
• Neptune: 14 moons, H/He/methane, rings.

So:

• Inner Planets:
• Planet C (no moons, volcanic → Earth/Venus-like).
• Planet D (red planet, CO₂, two moons → Mars).
• Planet E (thin atmosphere, no moons → Mercury/Venus).
• Planet B: “has rings but not much atmosphere”—contradicts, but maybe a mistake. If we follow “rings = outer,” then Planet B is outer.

• Outer Planets:
• Planet A (67 moons, H/He → Jupiter/Saturn).
• Planet F (27 moons, H/He/methane → Uranus).
• Planet B (rings → outer, even with “not much atmosphere” as simplification).

Final classification:

Inner Planet	Outer Planet
Planet D	Planet B
Planet E	Planet F

(Note: Planet B’s “not much atmosphere” is inconsistent with outer planets, but rings are a key outer planet trait. Likely a simplification in the problem.)

Answer:

Inner Planet	Outer Planet
Planet D	Planet B
Planet E	Planet F
