Quizplus · Accepted Answer

Volcanic activity on early Earth played a crucial role in shaping the planet's atmosphere and hydrosphere. It released gases such as carbon dioxide, nitrogen, and water vapor. These gases contributed to the formation of the early atmosphere, and the water vapor eventually condensed to form the first oceans. Oxygen for photosynthesis, however, was not a direct product of volcanic activity but rather a result of biological processes, primarily carried out by cyanobacteria, much later in Earth's history.
