How do we know what is inside the Earth and planets? What are the dynamic processes that shape the Earth? This course will use a physics-based approach to investigate these questions and develop an explanation for what drives plate tectonics, the origin of planetary magnetic fields, and the causes of hazards such as earthquakes and volcanoes. You will learn about the methods that are used to image the interior structure and dynamics of the Earth and other planets. You will also learn how these methods are applied in resource exploration, environmental monitoring, satellite missions to other planets and moons, and other scientific studies of the Earth system. The different career options available in geophysics will be discussed. Prerequisites: Physics 20 and Mathematics 30. Note: Credit will be given for only one of GEOPH 110 or 210.
