Life in Earth is based on a diversity of physical and chemical dynamism and processes of Earth in the 4 billion years of history. It is substantially said as the history of interrelation between Life, Water, Mineral (Solid Earth) and Atmosphere. Interdisciplinary approach, way of thinking and communication are necessary. This session will be a cradle for such kind of interdisciplinary research.
