Oxygen is not typically released directly by volcanoes. Volcanic eruptions primarily release gases such as water vapor, carbon dioxide, sulfur dioxide, and other gases from the Earth's mantle and crust. Oxygen is already abundant in the atmosphere, primarily produced by plants through photosynthesis.
The first source of oxygen in our atmosphere was likely the photosynthesis of cyanobacteria, also known as blue-green algae. Over time, these microorganisms released oxygen as a byproduct of their metabolic processes, gradually increasing the oxygen levels in Earth's atmosphere.
Sulfur is not produced by volcanic outgassing, as it is a solid mineral that can be released during volcanic eruptions but is not a gas emitted directly from volcanoes.
Oxygen is released from the molecule water (H2O) during the process of photosynthesis in plants.
Oxygen released comes directly from the water used as a reactant. A plant enzyme splits water into protons, electrons and oxygen, with the electrons replenishing lost electrons in pigments, protons used to maintain the electrochemical gradient, and oxygen released as waste.
Oxygen was produced by early photosynthetic organisms, such as cyanobacteria, which released it as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere, leading to the levels we have today.
Volcanoes do not release oxygen; they re;ease other gasses such as carbon dioxide and sulfur dioxide. The oxygen on earth is released by photosynthesizing organisms such as plants and algae.
Volcanoes released gases like water vapor, carbon dioxide, and sulfur dioxide during eruptions. These gases reacted with sunlight and water vapor to form oxygen molecules, contributing to the initial oxygen in the atmosphere.

Yes. One of the common gasses released by volcanoes is sulfur dioxide. This reacts with water and oxygen to form sulfuric acid.
No. A volcano erupts molten material from inside the earth. Actual fire is not involved:the material is hot to begin with and has been since the formation of the earth.

Volcanoes release H2S, HCl, SO2, CO2, etc.
Volcanoes did not produce oxygen in the Precambrian era. The composition of volcanic gases during this time period mainly consisted of carbon dioxide, water vapor, and sulfur gases, but minimal oxygen was present due to the lack of photosynthetic organisms producing it.
