Which statement describes the density of the inner planets? all the inner planets are dense the inner planets are less dense than the outer planets earth is dense , while the other planets are not. mercury and venus are dense, while earth and mars are not.

All the inner planets are dense.

Option (1)

Explanation:

The density is a contrasting factor that marks the materials that are occupied by the planets in space. Our solar system is comprised of 8 planets of which the inner four planets are known as the inner terrestrial planets and the outer four planets are known as the outer terrestrial planets. They are separated by a large asteroid belt.

The inner planets are nearer to the sun and are highly dense in comparison to the outer planets. The density of these inner planets is more than 5 g/cm³ on an average except Mars which has a density of about 3.9 g/cm³. Whereas, the density of the outer planets is very less, which is less than 1.7 g/cm³ on average.

So, from the above data, it can be concluded that all the inner planets are denser than the outer planets.

Hence, the correct answer is option (1).
