Eruption
Some of the trapped gas in a magma will be water vapour, but at very high temperature. As the magma rises in the volcanic pipe, the pressure will lower, and the entrained vapour will expand rapidly = an explosion.
The force that causes magma to erupt to the surface is primarily due to the build-up of pressure from the expansion of gases within the magma chamber. As the pressure exceeds the strength of the surrounding rock, the magma forces its way through the crust to reach the surface, resulting in an eruption.
In general chemistry we are taught the ideal gas equation of state PV=nRT. n is the number of moles of gas and R is the molar gas constant. This is an extremely important equation in the study of thermodynamics.
When gas hydrates are brought to the surface, they lose stability due to the change in pressure and temperature. As a result, the hydrates dissociate into gas and water, releasing the trapped gas. This release of gas can cause pressure build-up and potentially lead to explosions or other hazards.
Increasing the temperature the pressure of the gas increase also.
CFC's get trapped. They react with ozone to deplete it.
The danger is, if the infrared is trapped by atmospheric gases it can cause greenhouse effect.

Yes, it contain methane.

Traffic fumes trapped under a low layer of cloud on a calm day is the primary cause.

No, the fact that the magma has such a low density is why it rises. However, gasses do effect the manner in which it erupts.

The build up of greenhouse gases is trapping more heat, causing global warming and climate change.
A heavy meal can precipitate angina due to the pressure and gases that build up after this activity. Meals that are high in sodium and can cause water retention around the arteries or constrict the blood vessels commonly are the culprit in these situations.
