This course focuses on the practical applications of the continuum concept for deformation of solids and fluids, emphasizing force balance. Topics include stress tensor, infinitesimal and finite strain, and rotation tensors. Constitutive relations applicable to geological materials, including elastic, viscous, brittle, and plastic deformation are studied.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

The Earth’s crust is primarily composed of melting products from mantle plumes and mid-ocean ridges - both presently and over the course of Earth history. While both systems represent upwelling features in a convective mantle, they can be viewed as end-member systems in that plumes represent buoyant flow whereas mid-ocean ridges represent passive corner flow. This paradigm is not strict - flow beneath ridges may be buoyant in some places, for example, but it does provide a reasonable framework for enquiry. Plumes and ridges can be studied independently, but in many places across the globe the systems interact, often in intriguing fashion. The nature of these interactions provides an opportunity to improve our understanding of both systems, and provides new perspectives on the mantle, crustal, and water column processes associated converting heat from the Earth’s interior into new crust, hydrothermal flow, and biological communities on the seafloor. The approach taken for the 2001 Plume-Ridge Interactions Seminar series was to start with basic ideas about mantle convection and tectonics, and an overview of the global hotspot and ridge systems. We then addressed three case studies of plume-ridge interactions in detail. Our first case was the interaction of the. Each of these systems provides a different perspective on the nature of plume-ridge interactions, and by comparison and contrast we are able to distill the fundamental aspects out of the complex array of geophysical and geochemical data associated with plume-ridge systems.

In this course, principles of thermodynamics are used to infer the physical conditions of formation and modification of igneous and metamorphic rocks. The course includes phase equilibria of homogeneous and heterogeneous systems and thermodynamic modeling of non-ideal crystalline solutions. It also surveys the processes that lead to the formation of metamorphic and igneous rocks in the major tectonic environments in the Earth’s crust and mantle.

Students learn about the causes, composition and types of volcanoes. They begin with an overview of the Earth's interior and how volcanoes form. Once students know about how a volcano functions, they learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an eruption, seeing how a volcano gets its shape and provides us with clues to predict a blast.
