What exactly does it mean to be a gaseous planet
[From: ] [author: ] [Date: 11-12-26] [Hit: ]
The terrestrial planets (planets with a rocky surface) have a core mainly made of iron and could be a solid or a liquid layer. The Earths core is partially liquid, while the cores of Mars and Venus are thought to be completely solid, because the cores do not make a magnetic field.The gas giants also have a core made of iron. Their cores are very small,......
Now imagine that when you went through 100 kilometers of atmosphere instead of finding dirt, you found more gas. The process would continue. Here on earth, we have dry ice - solid CO2 - which we create by chilling and it sublimes directly to gas without melting - but like all vaporization processes we can stop that by containing the block and increasing the pressure. On Jupiter, as we go deeper and deeper into the atmosphere it gets thicker and thicker and higher and higher pressure until - if our ship could survive - it would be like moving in water then tar and then be solid while still containing what we consider gas molecules.
Where does this occur? We don't know - but Jupiter is about 70,000 kilometers radius so we are talking thousands and thousands of kilometers above the center

what it means is that a gaseous planet has a rocky core surrounded by by a very thick atmosphere and the rocky core can be surrounded by a lot of ice as well as a thick atmosphere
"...The planetary core is the innermost layer or layers in a planet. The terrestrial planets (planets with a rocky surface) have a core mainly made of iron and could be a solid or a liquid layer. The Earth's core is partially liquid, while the cores of Mars and Venus are thought to be completely solid, because the cores do not make a magnetic field.
The gas giants also have a core made of iron. Their cores are very small, in proportion to their large size. However, the gas giants are so large that their cores can still be larger than the Earth's core. Jupiter's core is estimated to be 12 times the mass of the Earth's.
A core's size can vary from each planet or other object. The moon's core is 20% of its radius, but Mercury's core is 75% of its radius..."

The outer core of Venus is very likely likely liquid just like Earth's core is. The ONLY reason that Venus does not have a global magnetic field is because it rotates to slowly to maintain the magnetic dynamo that is required to generate a global magnetic field. ALL of the Jovian planets rotate more rapidly than Earth does, and they all have much stronger GLOBAL magnetic fields than Earth does.

Instead of "dirt" like what Earth is made of, a gaseous planet is composed mostly of gasses such as hydrogen and helium. You wouldn't be able to land on it, you would just keep sinking down until your spacecraft is eventually crushed by the pressure of all the gasses above you.

what exactly does it mean to be a gaseous planet?
It means that a good portion of the planet's mass is in a gaseous state.

Means gaseous

1. it means its a composition of gas
2. no nothing can
3. i dont think so but im no expert here
