A basic, simplified answer is:
The inner planets are mainly rock with iron cores.
The outer planets are mostly gas, or liquefied gases.

the outer planets are gaseous and the inner planets are not
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.
The inner planets are hotter because they are the closest to the sun the outer planets are the coldest because they are the farthest planets from the sun
The inner and outer planets are alike in that they are all part of our solar system and orbit around the Sun. They also have varying sizes and compositions, with the inner planets being smaller and rocky while the outer planets are larger and gaseous. Additionally, they all have moons, but the outer planets tend to have more and larger moons compared to the inner planets.
Shape, rotation-direction, and orbit-direction.
The inner planets are small and rocky, the outer planets are much larger and have no solid surface, they are called the gas giants.
inner=terrestrial outer=non terrestrial
the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
The inner planets are like big rocks. The outer planets are like big balls of gas.
They are all bigger
smaller
