What is differences between rock planets and gas planets?

Answer 1

The Rocky Planets are:

• Mercury
• Venus
• Earth
• Mars
• Pluto (considered to be rocky most of the time)

The Gaseous Planets are:

• Jupiter
• Saturn
• Uranus
• Neptune

The first four planets (Mercury, Venus, Mars, and Earth) are called the inner planets which are closer to the sun and stripped of their light gasses by the sun's solar winds. The solar winds then carry the debris (elements) to where the winds tend to "die down" which is right near Jupiter. Thus, all the debris is mostly swept up by Jupiter and Saturn (which is why they appear so large), however, Uranus and Neptune are less gaseous because they are just so far away from the sun. Therefore, the first four planets are dense with a hard iron core, whereas the last four planets are gaseous and BIG.

Answer 2

The composition (the "stuff" they are made of) of the two types are very different.

Terrestrial planets, or "rock" planets, are composed mainly of metals and/or silicate rocks.

They tend to be (relatively) small in size.

Jovian planets, or "gas" planets, are obviously composed of gasses. Hydrogen (H) and Helium (He), are usually in high abundance, along with trace amounts of other gaseous elements.

Interestingly, it is also theorized that some Jovians, such as Jupiter, may also have a solid core.

Finally, the composition of Uranus and Neptune differ from that of Jupiter and Saturn. While all are primarily H and He, the two most distant planets also have higher amounts of "ices". Examples are methane, ammonia, and H2O. Planets such as Uranus and Neptune are sometimes categorized as "ice giants".

Answer 3

Rock planets, such as Earth and Mars, have solid surfaces made of rocks and metals, while gas planets, like Jupiter and Saturn, are composed mainly of gases like hydrogen and helium. Gas planets are much larger and less dense than rock planets, and they lack solid surfaces. Gas planets also have thick atmospheres and are typically located further from the sun than rock planets.

Answer 4

The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The four outer gas giant planets are Jupiter, Saturn, Uranus and Neptune.

Answer 5

gas planets are made out of gas rock planets are made out of rocks that form together

Answer 6

the rocky planets are small, dense, and rocky, while the gaseous planets are huge, less dense, and made up mainly of gas

Answer 7

The four inter. Plants are rocky and the other plants are gases

Answer 8

Gas giants have small core made of rock while rocky inner planets have their very own bodies made of rock.
