Gas giants do not have solid surfaces like terrestrial planets do. Instead, their outer layers consist mainly of dense gases, such as hydrogen and helium. As you descend towards the core of a gas giant, the pressure and temperature increase immensely, but it does not transition to a solid surface.

The Law of Solid Friction states that the force of friction between two surfaces is proportional to the normal force pressing the surfaces together and is independent of the contact area between the surfaces. This law applies as long as the surfaces are not in relative motion.
