Yes it is ^-^
atmospheric presures
temperature, pressure, volume, and density temperature, pressure, volume, and density
ice floats on top of water due to its lower density.... similarly, the gases with lower density lies in the upper atmospheric layers and the ones with larger density lie on the lower most atmospheric layers. so the overall density of air decreases with height.
density of air at 10 degC and atmospheric pressure is 1.249 kg/m^3
The amount of water vapor in air varies based on the temperature and density of air. The amount of water vapor ranges from a trace amount up to 4%.

Gravity. Atmospheric pressure is the weight of a column of air. Of course, the temperature of that air changes it's density and therefore it's weight (i.e. pressure)
Sorry, the atmospheric pressure has really nothing to do with the speed of sound at 0c, but he temperature is very important Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure". The air pressure and the air density are proportional to each other at the same temperature.
In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.
Well as you increase in altitude the air thins, because you are getting higher in the Earth's atmosphere which has less density then lower atmospheric levels which makes the air thin.
Temperature - low temperature gains altitude quicker Pressure - High pressure gains altitude quicker Density - Low density gains altitude quicker
Density = mass divided by volume. Mass is determined by the individual atoms or molecules and their compression (how close together they are). Compression is affected by external elements such as temperature and atmosphere. Temperature can increase or decrease density (hotter temps lead to decrease in density as atoms separate). Atmospheric pressure can also change the density (air is less dense the further you get from Earth/higher you go in the sky).
Both pressure and volume of any gas are directly, linearely proportional to temperature in Kelvin, that is degree Celsius + 273.13. Density is not directly related to temperature, it is related to mass and volume.
Winds follow air pressure gradients and these are determined by atmospheric density.
