Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no real atmosphere due to its small size and proximity to the sun.
The atmosphere on Venus is very thick, giving it a high surface pressure, some 93 times that of the Earths. Carbon Dioxide makes up around 96.5% of the atmosphere with around 3.5% Nitrogen. There are also small amounts of sulfur dioxide (0.0015), carbon monoxide (0.0017%), water vapour (0.002%), argon (0.007), helium (0.0012%) and Neon (0.0007%)
Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide. Around 1% of the atmosphere is water vapour, with traces of other gases such as Neon, Xenon and Carbon Monoxide. Earths atmosphere is thicker than Mars', but not nearly as thick as Venus'.
Mars has a thin atmosphere, mainly of Carbon Dioxide (95.32%). Nitrogen makes up 2.7%, Argon 1.6%, Oxygen 0.13% and Carbon Monoxide makes up around 0.08%. There are other trace gases such as Water Vapour, Neon, Krypton, xenon, Molecular Hydrogen and Nitric Oxide. Mars' surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.

What planet has a thick atmosphere has no moon and its rocky?
well there are no planets like that
What type of mars is it rocky or gas planet?
Mars is a rocky planet.....the 4 inner planets are rocky and the 4 outer planets are gas (gas giants)
What feature separates the rocky planets from the gas planets?
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.
What is the other type of planet other than gaseous?
The first four planets (Mercury, Venus, Earth, and Mars) are known as "Rocky planets" because they have a surface that you can stand on.
How many rocky planets are there in the solar?
4 rocky planets
Which rocky planets have well-developed atmospheres?
Only Earth and Venus has a well developed atmosphere out of the rocky planets. Note that the rocky planets are Mercury, Venus, Earth and Mars.
What type of planet is rocky or gaseous?
The "terrestrial planets" are rocky and the "gas giant planets" are gaseous.
Is Mars made of gas or rock?
No. Mars has a rocky surface and a metallic core.
What planet has a thick atmosphere has no moon and its rocky?

Which have well developed atmospheres?
Only Earth and Venus has a well developed atmosphere out of the rocky planets. Note that the rocky planets are Mercury, Venus, Earth and Mars.
What type of mars is it rocky or gas planet?
Mars is a rocky planet.....the 4 inner planets are rocky and the 4 outer planets are gas (gas giants)
Which of the rocky planets have well developed atmospheres?
The two largest, Earth and Venus, have a mass large enough to sustain an extensive atmosphere. The other two rocky planets, Mars and Mercury, are too small to hold such an atmosphere. There is some, but it is very thin.
What type of atmosphere do jovian planets have?
The atmosphere gets thicker and thicker as you go down; the planets basically consist mainly of atmosphere, though those planets are expected to have a solid core.

How is Mars and earth alike?
Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.
