All the inner planets are rocky or terrestrial planets.
The inner planets at made out of rocks because of the sun and the falling rocks.
They are very small compared to outer planets, mostly made up of rocks, closer to the sun and they do not have rings.
Since the inner planets are composed mainly of rocks, they are heavier, and rotate slower.
The inner planets (Mercury, Venus, Earth, and Mars) are made primarily of rock.
Because the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
The inner planets at made out of rocks because of the sun and the falling rocks.
the inner planets made up of rocks while the outer planets are made up of gases and liquids.
Rocks
very close to the sun .they are made up of rocks .
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.
They are very small compared to outer planets, mostly made up of rocks, closer to the sun and they do not have rings.
Since the inner planets are composed mainly of rocks, they are heavier, and rotate slower.
The inner planets (Mercury, Venus, Earth, and Mars) are made primarily of rock.
The inner planets are like big rocks. The outer planets are like big balls of gas.
Because the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
rocks only they are compact and hard
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
