of coarse not it is made up of gases
Saturn is a gas giant and does not have a solid surface or a crust like terrestrial planets such as Earth. Its structure consists of layers of gas, liquid metallic hydrogen, and a rocky core, with no distinct solid surface.
It would be Venus, because that planet is the only one that has a solid crust.
Earthquakes are caused by the movement of tectonic plates (the plates that make up the crust of the earth). Saturn, being comprised of solely gas, can therefore have no earthquakes.
Technically, since Saturn is a jovial planet, the "crust" is actually gas. The gas gets pretty deep, about 1,000,000,000km deep! Sorry if I'm a bit off.
Jupiter's moons - Europa and Ganymede possibly have oceans of liquid water under their crust. Saturn's moon - Enceladus also has a possible ocean of water under it's crust.
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
I'll assume you meant to say the gas giant planets (Jupiter, Saturn, Uranus, and Neptune). No they do not have thin crusts.
Dione is one of the moons of Saturn. It is an icy moon that has been suggested might have a liquid layer running underneath the icy crust.
Saturn is made up of gases. 94% hydrogen, 6% helium and small amounts of methane and ammonia
Saturn, like other gas giants, does not have a solid surface with distinct crust, mantle, and core layers like terrestrial planets. Instead, it is predominantly made up of hydrogen and helium gases with no solid surface. Its interior is composed of layers of gas that transition into a dense, metallic hydrogen layer towards the core.
