they all have different gasses in there atmosphere
The atmosphere gets thicker and thicker as you go down; the planets basically consist mainly of atmosphere, though those planets are expected to have a solid core.
They consist mostly of gas.
They are very large, and consist of mostly gases.
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
Jovian planets do not have a solid surface, therefore their atmospheres are thick all the say to where their surface would be. Their atmospheres have more gasses than those surrounding terrestrial planets.
Jovian Planets do not have a solid surface to stand on.
Inner planets are terrestrial planets outer are jovian planets
The cores of jovian planets are very similar to terrestrial ones. Jovian planets are simply a more evolved form of terrestrial planet contrary to popular perception. Jovian planets often have a lot of hydrogen, helium, methane, and/or volatile ices to make up its atmosphere to the point where oceans of these components cover the terrestrial core and billow the atmosphere to large proportions. Terrestrial planets absorbed less of these components from the leftover solar nebula leaving only the rocky surface and maybe some gas of an atmosphere.
Jovian planets are: -gaseous -farthest planets from the sun -largest planets
Because Jupiter is mainly hydrogen.
The Jovian planets are gas giants and have no surface.
When you look at Jovian planets through a telescope or view images of them, what you see is not their surface, but the outer layer of an extremely dense atmosphere. At depth, immense pressure from thousands of miles of atmosphere turns gases into liquids.
