Question

in what way is earth like the other inner planets? choose the correct answer. it has a relatively high density. it has liquid water on its surface. it has a mostly hydrogen and helium core. it revolves around the sun in 24 hours or less.

Explanation:

Inner planets (Mercury, Venus, Earth, Mars) are terrestrial, with high density (rocky/metallic). Earth has high density like them. Other options: Rotation period (Earth’s rotation is ~24h, but inner planets’ rotations vary; gas giants have H/He cores; liquid water is unique to Earth among inner planets, not a similarity). So "It has a relatively high density" is correct.

Answer:

A. It has a relatively high density. (Note: Assuming option labels, but based on content, the correct statement is "It has a relatively high density" as inner planets are dense, terrestrial; Earth shares this with them. The other options: rotation period isn't a shared inner - planet trait (e.g., Venus rotates slowly), gas giants have H/He cores, and liquid water is Earth - unique among inner planets.)
