I believe it is mostly gas.
Air,gas,and rocks
Neptune does not have any surface terrain. The planet only consist of gases, such as hydrogen and helium, along with small rocks within the gas.
No. Neptune is a gas giant. Therefore it does not have a surface or solid rocks. Therefore there is nothing for anything to impact on and it is impossible for volcanoes to form.
Volcanoes - No. Craters - No. Rings - Yes. Neptune is a gas giant. A gas giant does not have a solid surface or rocks. Therefore it is impossible for impact craters and volcanoes to form. Neptune has very faint blue-white rings that are very difficult to see.
Neptune is a gas giant composed mostly of hydrogen and helium, with no solid surface. Its atmosphere is made up of thick layers of gas and ice, blending seamlessly into a liquid mantle below. As a result, there are no valleys present on Neptune's surface as there is no solid ground for them to form on.
Neptune is mostly gas.
Neptune is mostly made of gas. Also, Neptune has rings and clouds. BY: jill the queen of awesome
no there is no ice in the core of neptune. in the core of neptune, is just gas. the planet neptune is just gas
No. Neptune is one of the outter planets, which would make it a gas giant so there is no way possible.
Neptune is an "Ice Giant" planet. Neptune's atmosphere is composed primarily of hydrogen and helium. We can not see the surface but we believe the surface is primarily composed of ices and rock and the planet has a hot core.
No. It is made largely of gas and various ices with a small rocky core.
Yes. Neptune is one of the gas giants.
