The gases that come out of volcanoes are water vapor follwed by carbon dioxide and sulfur dioxide.

I understand but i want to know the %'s. Do they give off more sufur dioxide or carbon dioxide?

Volcanic gases are those that are expanding and being released from entrapment in super hot magma as they near the surface. They would include water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and others.

Magma contains dissolved gases that are released into the atmosphere during eruptions. Gases are also released from magma that either remains below ground or is rising toward the surface. Gases can escape into the atmosphere from the soil, volcanic vents, fumaroles, and hydrothermal systems.

Volcanic gases are formed from combinations of elements present in magma that are in their gas phase; under normal atmospheric pressure and temperatures some of the elements would normally be in a liquid or solid phase. Their rapid expansion due to the release from pressure as they rise to the surface can result in explosive eruptions.

Outgassing is the release of gases either trapped in liquid rock (magma) or generated by the contact of the heated rock with underground water. These gases include water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. The sulfur compounds are especially dangerous to humans and animals, and can lead to "acid rain" when released into the atmosphere.

Superheated gases also form part of the heavy ash clouds called pyroclastic flows.

The concentrations of different volcanic gases can vary considerably from one volcano to the next. Water vapor is typically the most abundant volcanic gas, followed by carbon dioxide and sulfur dioxide. Other principal volcanic gases include hydrogen sulfide, hydrogen chloride, and hydrogen fluoride. A large number of minor and trace gases are also found in volcanic emissions, for example hydrogen, carbon monoxide, halocarbons, organic compounds, and volatile metal chlorides.

What is Volcanic steam water cycle?

A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lavafragments.
