EU 7: Physiography and geological evolution of planets

The objective of this course is to provide general knowledge of comparative planetary geology by addressing key mechanisms that build and shape the planetary surface, ie: volcanism, tectonics, and impact craters. The courses also cover basic methods for planetary geology such as age estimate using crater density. The module takes into account various aspects of Earth Sciences (geology, geophysics, geodynamics) and more specific aspects to the planets (impact craters). Students will have to read and discuss scientific article for each theme.

NB : The water cycle on Mars will be addressed in the module "Climate Systems and Evolution of Planetary Atmospheres."
