I guess that the atmosphere would change in terms of depth if the planets temperature changed enough.
Like on earth, atmosphere pressure is higher where elevation is lowest. The depth of Valleys and Impact craters, with depth of up 8000 meters, have the thickest atmosphere.
The primary change is of pressure, increasing at 1 Bar per 10 metres of depth; but in the oceans, the temperature and salinity also alter in subtle ways.
It would need around 4x1018 kg of air to raise Mars' atmosphere to earth's atmospheric pressure. The answer is formulated under general pressure-depth relation assuming ratio of atmosphere depth is very small to the planet's diameter. P = m.g/A P = pressure = 101300 Pascal at earth's sea level m = mass of air [=] kg g = Mars gravity = 3.7 m/s2 A = surface area of Mars [=] m2
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.

As a gas planet, Neptune does not have a definite surface. It has an atmosphere of hydrogen, helium, and methane that gradually becomes denser with depth.
When it comes to determining a gas giant's volume, diameter, etc., the "surface" is the depth in the planet's atmosphere at which the air pressure equals one atmosphere (the same air pressure as in the earth's atmosphere at sea level).
10 meters of water depth equals about 1 atmosphere.
Like on earth, atmosphere pressure is higher where elevation is lowest. The depth of Valleys and Impact craters, with depth of up 8000 meters, have the thickest atmosphere.
Pressure drops at higher elevations because of the decrease in the weight of air. Under the water, pressure climbs with increasing depth because of the combined weight of the water and that of the atmosphere.
Yes, Its a gas giant, so it has thick atmosphere that just gets thicker with depth. The upper layers are mainly Hydrogen and Helium, but there is also a bit of Methane which give the planet its greenish hue. The composition changes as you go deeper into the planet.
4 atmospheres is about 135.6 feet of water depth.
How does liquid pressure vary with depth
the planet's size
How does liquid pressure vary with depth
It is the lowest section of our atmosphere, with an avg. depth of 11km (7miles). Contains 75% of atmosphere's mass.
Because water is denser than air.
