Which of the following is a characteristic of outer planets? a) close to the sun b) few moons c) have rings d) rocky surfaces

The following characteristic of the outer planets is C. Have rings.

Jupiter, Saturn, Uranus, Neptune have rings. Although Jupiter looks like it doesn't have it, it is still part of the outer planets.

The outer planets are not close to the sun that is the inner planets (Mercury, Venus, Earth and Mars). They have a lot of moons, more than the inner planets. And lastly they don't have rocky surfaces in fact they're surface is clouds and gas.

Hope this helped :)

have a great day  

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
