It's atmosphere is mostly hydrogen, helium and methane gases.It is made of gases
Neptune is a gas giant (or ice giant) planet and has no solid surface visible to us. It is believed that beneath the thick atmosphere the surface of Neptune is mainly composed of ices, although there is probably a rocky core beneath these. We therefore have no way of knowing what the rock types on Neptune actually are but it is believed that the core of Neptune is composed of iron, nickel and silicates, with an interior model giving a mass about 1.2 times that of the Earth. The link below is a diagram of Neptune's structure.
here is no surface to Neptune, But it has a rock core
Neptune is mostly gas.
All rock types can be formed from any other rock type.

A metamorphic rock.
rock
no,infact Neptune is a gas planet with no solid surface
A metamorphic rock.
The surface gravity of Neptune is thought to be about 1.14 times the gravity on Earth, so 100 kg on Earth would weigh about 114 kg on Neptune--except that Neptune is a gas planet and has no solid surface on which the 100kg rock could be weighed.
Salt and watermelon probably
It has ice rock and hydrogen
