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.

Is earth made up rock?
Yes the earth is made up of rock. The planets near the sun like mercury,Venus,earth and mars are made up of solid rock but the planets in the outer region like Jupiter,Saturn,Uranus and Neptune are made up of gas.
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.
Why was Earth and other planets not solid when they first formed?
They were made of dust, not rock
What are the four solid planets made of?
these planets are small rock solid planets.
Why are inner planets also called rocky planets?
The inner planets, except earth, are made up of rocks. They have a hard surface. The earth would be one of these except we have water. The outer planets are gas giants and do not have a solid surface.

What are rocky planets?
The Rocky planets are Mercury, Venus, Earth and Mars. They are all the planets with a solid surface made of rock.

Why are some planets called terrestrial planets?
There word terrestrial contains the Latin root terrawhich means "earth." The term refers to planets that are similar to Earth in having solid, rocky sufaces. The other main category of planets are jovian planets, like Jupiter, which are made mostly of gas.
What are the four solid planets made of?
these planets are small rock solid planets.
Which planets are made of a solid?
Mercury, Venus, Earth and Mars. All the rest are gas giants
What matter are planets made of?
Mercury, Venus, Earth, and Mars are the solid rock planets. While Jupiter, Saturn, Uranus(lol get it), and Neptune are made up of gas
Why are inner planets also called rocky planets?
The inner planets, except earth, are made up of rocks. They have a hard surface. The earth would be one of these except we have water. The outer planets are gas giants and do not have a solid surface.
Is earth a solid or a gas planet?
Earth has a solid metal inner core and a liquid metal outer core. Most of the rest made up of rocks in a molten state, but with a solid "crust". Finally there is a gas atmosphere.For simplicity scientists call Earth a solid planet to distinguish it from the gas planets, like Jupiter.

What is the planet compositons of all the planets?
No; the basic answer is that some are solid rock, like the Earth and Mars, but the Outer planets are, as far as we know, simply massive balls of gas with no discernible land.
