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:

The inner planets (Mercury, Venus, Earth, Mars) are terrestrial. They have solid, rocky surfaces. Their density is relatively high compared to outer (gas) planets. Words like "giant" and "gaseous" describe outer planets. "Smooth" is not a general characteristic of inner planets (e.g., Mars has craters, mountains).

Answer:

rocky, solid, dense
