Earthquakes, volcanoes, mountain building, ice ages, landslides, floods, life evolution, plate motions—all of these phenomena have interacted over the vast expanses of deep time to sculpt the dynamic planet that we live on today. Planet Earth presents an overview of several aspects of our home, from a geological perspective. We begin with earthquakes—what they are, what causes them, what effects they have, and what we can do about them. We will emphasize that plate tectonics—the grand unifying theory of geology—explains how the map of our planet's surface has changed radically over geologic time, and why present-day geologic activity—including a variety of devastating natural disasters such as earthquakes—occur where they do. We consider volcanoes, types of eruptions, and typical rocks found there. Finally, we will delve into the processes that produce the energy and mineral resources that modern society depends on, to help understand the context of the environment and sustainability challenges that we will face in the future.

Meilleurs avis pour LA PLANÈTE TERRE... ET VOUS !
very interesting course and both profs are extremely interesting! love that they provide a transcript for the videos as well.
A great course! It is easy to follow and complete it. Good for students who are interested in geology but have no prior knowledge about it.
Excellent course. The content was well delivered. If you are not a geology student and don't intend to be one but wish to find out more about the planet you lived on, this is the course for you.
The professors make learning fun and fruitful. This course is interesting and provides great insights into Mother Nature and why we should protect the one and only home we have.
