An Astonishing Journey

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.




Learn about

  • Air and Weather


  • Earthquakes


  • Earth’s Structure


  • Jungles and Deserts


  • Minerals


  • Natural Disasters


  • Plate Tectonics


  • Rocks Fall Downhill


  • The Rock Cycle


  • Volcanoes


  • And more..





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.
