The inner planets are mostly made of iron and rock.
An inner planet is mostly made of iron and has more mass than outer planets, outer planets are mostly made of gasses, makeing them have less mass. The inner planets are the planets between the asteroid belt and the sun
Mercury is a rocky planet.It's actually a rock because it is one of the inner planets that are all made of rock.The planet Mercury is a dense, rocky, airless world.
Mars. The soil of this planet is rich in iron oxide, which gives the planet a characteristic color. >:)

None. By definition a rocky planet is mostly rock. Venus, by far, has the densest atmosphere of the terrestrial planets, but the planet itself is mostly rock and is similar in composition to Earth.
The inner planet that has an atmosphere containing mostly carbon dioxide is Venus. It has an extremely dense atmosphere, made up mostly of carbon dioxide with small amounts of nitrogen and trace amounts of other gases. The thick atmosphere contributes to Venus' extreme greenhouse effect, making it the hottest planet in the solar system.
Mercury is a rocky planet.
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.
Earth is covered mostly in water, but is not made up mostly of water. Most of earth is made of rock.
Earth is the planet that is mostly made of liquid water, covering approximately 71% of its surface.
