Question

which three words best describe the composition of the inner planets?
solid, smooth, giant
rocky, solid, dense
giant, dense, gaseous
gaseous, smooth, small

Explanation:

Inner planets (Mercury, Venus, Earth, Mars) are terrestrial planets. They have solid, rocky surfaces and are dense compared to gas giants. "Giant" and "gaseous" describe outer planets, and "smooth" is incorrect as inner planets have varied, cratered/rugged surfaces.
