一、課程簡介:
This course will introduce the fundamental continuum physics applied in understanding the working of plate tectonics, mantle convection and a variety of geological processes. The material of the course contents will present the mathematical concepts as less as possible unless they are essential to understand the physical principles. They will cover basic elasticity and fluid mechanics involved in the studies of the bending of elastic plates, the heat transfer through conduction at thermal boundary layers and mantle convection, and rheology that describes the relation between applied stress and strain (deformation) in the interior of the earth.
