Because they 4 inner planets are nearer the Sun, which warms them with its heat.
Inner planets. are inner & outer planets. are outer
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
The inner planets are smaller than the outer planets.
The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
The "inner" planets are on the "inside" of the asteroid belt, while the "outer" planets are on the "outside" of it
Inner planets
The inner ones are hotter and the outer ones are colder
Inner planets. are inner & outer planets. are outer
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
the outer planets are gaseous and the inner planets are not
because inner planets are hot and outer planets are cold
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
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.
yes the inner planets are much smaller then the outer planets
The inner planets are smaller than the outer planets.
Planets closer to the sun will receive more of the suns energy per unit of area on their surface than planets further from the sun, so will generally be hotter.
