Question

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 inner planets are not. mercury and venus are dense, while earth and mars are not.

Explanation:

The inner planets (Mercury, Venus, Earth, Mars) are terrestrial planets made of rock and metal. Their composition leads to higher density compared to outer gas - giant planets. Earth is dense, but so are Mercury (density about \(5.427\ g/cm^{3}\)), Venus (\(5.243\ g/cm^{3}\)) and Mars (\(3.9335\ g/cm^{3}\)). The outer planets (Jupiter, Saturn, Uranus, Neptune) are gas or ice giants with lower average densities. For example, Saturn has a density of about \(0.687\ g/cm^{3}\) which is less than water.

Answer:

All the inner planets are dense.
