The Earth
Neptune is mostly made of gas. Also, Neptune has rings and clouds. BY: jill the queen of awesome
Pluto is probably nearly 50% water ice. Of course, it was demoted to "dwarf planet" status.
Jupiter is mostly made of hydrogen and helium, with small amounts of other elements like methane, ammonia, and water vapor. Its interior is thought to contain a dense core of rock and metal surrounded by layers of liquid metallic hydrogen.
Earth is the planet that fits this description. It contains approximately 70% water on its surface and its atmosphere is primarily composed of nitrogen, with oxygen being the second most abundant gas.
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.
Earth is covered mostly in water, but is not made up mostly of water. Most of earth is made of rock.
The surface of planet Earth is made up of 71% water.

Yes, but not liquid water. The surface of Titan is made mostly of ice. It also has lakes and rivers of liquid methane.
It's mostly made up of gas (including liquid hydrogen). The core is probably rock and ices.

No planet is composed of mainly frozen water; Mars has probably the most frozen water of all the planets after the Earth. However, older textbooks and teacher's notes may well refer to Pluto, which is now classed as only a "dwarf planet" and is composed of roughly 50-70 percent rock and 30-50 percent ice. So, although Pluto has a lot of ice, it has more rock than ice (frozen water).
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.
