- Title
Volcanoes and Earth's Oxygen.
- Abstract
The article discusses a study which suggests the presence of terrestrial volcanoes increased oxygen in the atmosphere, allowing oxygen-breathing organisms to flourish. Researchers Lee R. Kump and Mark E. Barley discovered that increased terrestrial volcano activity occurred in the Palaeoproterozoic era due to the stabilization of land masses and that submarine volcanoes reduced atmospheric oxygen.
