Classify each planet as an inner planet or an outer planet.

A. Planet A has 67 moons, and major parts of its atmosphere are hydrogen and helium.

B. Known as the red planet, planet D has high amounts of carbon dioxide in its atmosphere and has two moons.

C. Planet F has 27 moons, and its atmosphere is mostly composed of hydrogen, helium, and methane.

D. Planet B has rings but not much atmosphere.

E. Planet E has a thin layer of atmosphere but no moons due to the effects of the Sun's gravity.

F. Planet C has no moons but has high volcanic activity

A. Jupiter has 67 moons, and major parts of its atmosphere are hydrogen and helium - It falls in the category of outer planets.

B. Mars is known as the red planet, it has high amounts of carbon dioxide in its atmosphere and has two moons - It is an inner planet.

C. Uranus has 27 moons, and its atmosphere is mostly composed of hydrogen, helium, and methane - It is considered an outer planet.

D. Saturn has rings but not much atmosphere - Is an outer planet

E. Mercury has a thin layer of atmosphere but no moons due to the effects of the Sun's gravity - It is an inner planet.

F. Venus has no moons but has high volcanic activity - It is an inner planet.

The inner planets and outer planets are separated by a belt of asteroids that lies between Mars and Jupiter.

A: Outer planet (most likely Jupiter)

B: Inner planet (Mars)

C: Outer planet (maybe Uranus)

D: Outer planet (possibly Saturn)

E: Inner (most likely Mercury)

F: Inner (may be Venus)
