Hydrogen and Helium.
Gases
The main difference is size. Jovian planets are very large and terrestrial planets aren't. Jovian planets are also made of gas and terrestrials are made of rocks.
It is impossible for the jovian planets to have volcanoes, because they are made of gas.
The outer planets are mostly composed of gases and the inner planets are mostly made of rock, metals.
Hydrogen and other 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.
The four inner planets are made of rock . The outer planets are made of various gases and condenced gases. Hydrogen being prominante.

The Jovian Planets are Jupiter, Saturn, Uranus and Neptune.... Jovian means Made of Gas.

atmosphere is made up of gases in all planets. But if you mean planets that are mostly atmosphere, then those are gas giants (Jupiter, Saturn, Neptune, Uranus)
"Jovian" planets are considered to be mainly made up of various gases, and are also known as "gas giants". The Jovian planets are known as "Jovian" from the largest gas giant in the solar system: Jupiter. Jupiter, Saturn, Neptune, and Uranus (Haha, very funny) are all considered Jovian planets."Terrestrial" planets are thought of as rocky. A human being could maybe walk on its surface, in a goodspace suit.Terrestrial planets are planets like Earth. The terrestrial planets in our solar system are Mercury, Venus, Earth and Mars.I know I sound like a book, but so-be-it.
the terristrial planets(inner planets) are made of rock, they are soild, the jovian plants (gas giants or outer planets) are made of many gases, and Pluto doesn't not fit in any category, Pluto is a dwarf planet that is possibly a moon.
They are alike because they all have some time of gases.
