Question

which statement describes the size of the inner planets?
all the inner planets, except mercury, are large.
the inner planets are larger than the outer planets.
all the inner planets are smaller than the outer planets.
mars is a large planet, while the other inner planets are small.

Explanation:

The inner planets (Mercury, Venus, Earth, Mars) are terrestrial planets. The outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants (or ice giants in the case of Uranus and Neptune). The inner planets are much smaller in size compared to the outer planets.

• The first option is incorrect because Venus, Earth, and Mars are not large compared to outer planets.
• The second option is incorrect as inner planets are smaller than outer planets.
• The fourth option is incorrect as Mars is also small compared to outer planets.

Answer:

All the inner planets are smaller than the outer planets.
