What Best describes the inner planets of our solar system?

The inner planets of our solar system, also known as the terrestrial planets, include Mercury, Venus, Earth, and Mars. They are characterized by their rocky compositions, relatively small sizes, and higher densities compared to the outer gas giants. These planets have solid surfaces, and their atmospheres vary significantly, with Earth having the most substantial atmosphere capable of supporting life. Overall, the inner planets are closer to the Sun and exhibit more extreme temperature variations than their outer counterparts.
