Summary  This course takes the mathematics which students have learned in the prehonours Mathematics for Physics courses and applies it to the study of the Earth, extending mathematical skills and exploring the insights that can be developed through quantitative modelling of geological processes. Many examples and applications are drawn from the book "Geodynamics" by Turcotte & Schubert.
Topics covered include the following.
1) Vectors and their use in describing positions and directions on the Earth's surface.
2) Spherical geometry and plate tectonics.
3) Potential fields and the gradient and divergence operators applied to gravity and heat flow.
4) Ordinary differential equations applied to heat flow in the Earth.
5) The diffusion equation applied to timedependent heat flow into the Earth.
6) Teaching is by means of a series of "workshops", in which short lectures on the underlying mathematical techniques and their geological and geophysical applications are mixed with example classes.
