Unfortunately, the definition of a planet does not include it's composition.
So Mercury, Venus, Earth and Mars are classed as terrestrial planets - made up of rock, whereas Jupiter and Saturn's are classed as Gas Giants - not surprisingly, as they are comprised of mainly gases - hydrogen and helium, whereas Uranus and Neptune are classed as ice giants - yep, you've guessed it.
..and that is the planets in our Solar System, outside, most exoplanets are gas giants.
So all planets are not terrestrial.

JudyNo, not all planets are made up of solid materials like Earth. Some planets, such as Jupiter and Saturn, are mostly composed of gases, while others, like Mercury and Mars, have rocky surfaces but may not be entirely solid throughout. Additionally, some planets, such as Neptune and Uranus, have icy compositions.

Are the other planets in our solar system made up like earth?
No, Earth is the only planet with a o-zone layer all of the planets past Jupiter are mostly gases with little ground and all the planets ahead of Earth does not have water but they do have solid ground like Earth.
Is Jupiter terresrial?
No, Jupiter is not terrestrial. It is a gas giant planet made up primarily of hydrogen and helium, with no solid surface like terrestrial planets such as Earth.
Why was Earth and other planets not solid when they first formed?
They were made of dust, not rock
The surfaces of the inner planets are mostly made of?
The surfaces of the inner planets (Mercury, Venus, Earth, Mars) are mostly made of solid rock. This rock is composed of silicate minerals like feldspar, pyroxene, and olivine. Some planets like Venus and Earth also have significant amounts of metal elements like iron and nickel in their cores.
Are Jupiter and Saturn rocky planets or gas giants?
Jupiter and Saturn are gas giants, not rocky planets. They are primarily made up of gases like hydrogen and helium and do not have a solid surface like rocky planets such as Earth.
