Question

Which statement best describes the density of the outer planets?

All the outer planets have low density.

The outer planets are denser than the inner planets.

Saturn is dense, but the other outer planets are not.

Uranus and Neptune are dense, but Jupiter and Saturn are not.

Answer 1

All the outer planets have low density. Why? I'm sure you must have heard the term "Gas Giants". Mass is greater, but is overbalanced by density.

Answer 2

Hey...

It is the second statement which is correct because we know that from mercury till mars it is inner plants which is less dense while the outer plants especially Saturn,Jupiter and Uranus are dense...Therefore the first statement is false

The third statement is wrong because Jupiter is the most dense planet and it is not Saturn which us dense also Uranus is also dense...therefore this statement cannot be accepted

The fourth statement is wrong because Jupiter is the first most dense with Saturn in the second and Uranus and Neptune are only just dense and not the most dense...Thus this statement is also wrong making the second statement correct...

Thanks,

Hope it helps u...
