Life, rocks, and soil are closely linked by feedback mechanism on Earth's surface. Soil and rocks build the habitat for evolution and existence of animals, fungi and plants since the Precambrian. As biodiversity is rapidly changing nowadays, it is of major interest to describe the ecosystems in relation to the interaction of Bios and Geos. The session is open to contributions related to the interaction and feedback mechanism between life and geological environments throughout geological history. We encourage also those who discuss the interaction of humans with geological environments. It would be important to address the question: How does change and behaviour of life provide a tool to understand and predict changes in Earth dynamics e.g. natural radioactivity, earthquakes, neotectonic faults as the habitat for life?
