Course description and aims

Geodynamic phenomena such as earthquakes and volcanic eruptions are frequently observed in the Japanese island arcs, and this lecture aims at providing understanding of the geodynamics as a part of the physical and chemical processes within the Earth. By comparing basic theory and observations of mantle convection, the geodynamical phenomena are discussed for its elemental processes and mechanism in a quantitative manner.

Student learning outcomes

Concerning dynamical phenomena of solid Earth, in particular, crustal deformation and mantle convection, the basic equations and the principal behaviors of dynamics are explained. How key parameters such as Rayleight number and non-dimensional internal heat generation control the system, based on which the nature of boundary layers and heat-material transportation are understood, leading to overall grasp of the Eath's system and evolution.

Keywords

solidEarth, mantle, crust, convection, heat transportation, material differentiation

Competencies that will be developed

✔ Specialist skills Intercultural skills ✔ Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

While explaining the basic concepts and phenomena, we try to deepen understanding through questions-and-answers and discussion of interactive-type. In addition, several exercises for important subjects are provided to be answered as a paper.
