Definition
Interior degassing is the process of volatile elements, such as carbon, hydrogen, and oxygen, being released from the solid planetary body (i.e., the crust and mantle), into the atmosphere. This occurs through volcanism and volatile escape through the lithosphere as a result of intrusive magmatism and is influenced by large-scale, global processes such as mantle convection and plate tectonics. An important aspect of interior degassing is the chemical speciation of the volatile elements where, e.g., hydrogen can be outgassed as water (H2O) or dihydrogen (H2). Hence, it plays a major role in (the evolution of) the composition of the atmosphere.
