The silicate mantle and its dynamics have controlled the Earths internal cooling for over four billion years. Today, these dynamics are rather slow, but this was not always the case: shortly after the core/mantle separation, this reservoir was significantly melted, with dynamics like those of a magma ocean. Despite advances in analytical and numerical tools and a better understanding of the Earth’s internal structure, the Earths mantle currently remains a mystery. Structure and Dynamics of the Earths Interior 1 presents the evolution of mantle dynamics throughout Earth’s history, from its formation to the present day. It examines the contributions of numerical modeling, as well as the seismological, petrological and geochemical data used to constrain dynamic models. Finally, the book analyzes the manifestations of mantle dynamics in terms of surface cooling, volcanism and coupling with the atmosphere.
