Description

Continents move. Glacial cycles come and go. Mountains spring up and erode away. We live on a planet that is constantly in motion-except we see it in extreme slow motion. In this exciting course of 48 half-hour lectures, you effectively speed up the action to witness the history of our planet unfold in spectacular detail, learning what the Earth is made of, where it came from, and, above all, how it works.

An Astonishing Journey

How the Earth Works takes you on an astonishing journey through time and space. You will look at what went into making our planet-from the big bang, to the formation of the solar system, to the gradual evolution of the planet into what it is today. You will travel to the center of the Earth and out again, charting the geological forces that are constantly reshaping the continents and seafloor.

Earthquakes, volcanic eruptions, and tsunamis are byproducts of our planet's ceaseless activity, and you will focus on specific examples of each to learn why and when they occur. Earth's surface is mostly water, and you will explore the cycling of this vital substance throughout the planet, along with its role in climate, erosion, plate tectonics, and biology.

Not only are humans at the mercy of our planet's natural forces, but we ourselves have become agents of change. We are altering the Earth's land, water, and air faster than any geologic process, and this will be another theme of your journey.

Michael E. Wysession

Instructor's Courses

Dr. Michael E. Wysession is the Professor of Earth and Planetary Sciences at Washington University in St. Louis. Professor Wysession earned his Sc.B. in Geophysics from Brown University and his Ph.D. from Northwestern University. An established leader in seismology and geophysical education, Professor Wysession is noted for his development of a new way to create three-dimensional images of Earth's interior from seismic waves. These images have provided scientists with insights into the makeup of Earth and its evolution throughout history. Professor Wysession is the coauthor of An Introduction to Seismology, Earthquakes, and Earth Structure; the lead author of Physical Science: Concepts in Action; and the primary writer for the texts Earth Science, Earth's Interior, Earth's Changing Surface, and Earth's Waters. Professor Wysession received a Science and Engineering Fellowship from the David and Lucille Packard Foundation, a National Science Foundation Presidential Faculty Fellowship, and fellowships from the Kemper and Lily Foundations. He has received the Innovation Award of the St. Louis Science Academy and the Distinguished Faculty Award of Washington University. In 2005, Professor Wysession had a Distinguished Lectureship with the Incorporated Research Institutions for Seismology and the Seismological Society of America. In 2014, Wysession received the inaugural Ambassador Award of the American Geophysical Union.
