Geobiology is the study of the interactions between physical, chemical, and biological processes in the Earth's surface and subsurface environments. It encompasses the study of the origin, evolution, and distribution of life on Earth, as well as the impact of living organisms on the Earth's systems, including the atmosphere, hydrosphere, and geosphere. Geobiologists investigate a wide range of topics, including the evolution of early life forms, the biogeochemical cycles that sustain life, the influence of microorganisms on Earth's climate and geology, and the role of microbes in the formation of mineral deposits and energy resources.
