  • Tony Watts on the Mechanics of Tectonic Plates

    October 15, 2026 · 30 min

    By the end of the 1960s, plate tectonics had been widely accepted, but it rested on an untested assumption: that the plates are strong enough to move as rigid slabs. Tony Watts describes how, as a postdoc at the Lamont-Doherty Earth…

  • Torgeir Andersen on Ultrahigh-Pressure Metamorphism

    October 2, 2026 · 28 min

    Continental crust is buoyant, which is why continents stand high above the ocean floor. Yet rocks in western Norway contain microscopic grains of coesite, a form of quartz that forms only under pressures found about 100 km down. A slab of…

  • Brian Wernicke on Lithospheric Extension and the Basin and Range Province

    August 27, 2026 · 34 min

    Where tectonic plates collide, the result is clear: the edge of a plate crumples and throws up a mountain belt. But where a plate is stretched rather than squeezed, the evidence is usually lost, because the thinned lithosphere subsides and…

  • Bernhard Steinberger on Whether Hotspots Are Fixed

    July 16, 2026 · 29 min

    Volcanic island chains like Hawaii record the passage of a plate over a hotspot — a plume of hot rock rising from deep within the mantle. For decades, hotspots were assumed to be fixed, providing a stationary frame of reference against…

  • Sonia Tikoo on the Moon's Magnetic Field

    June 27, 2026 · 33 min

    We have known for decades that the Moon once generated a strong magnetic field — comparable in strength to Earth's — throughout the period from about 4.25 to 3.5 billion years ago. Only in the past few years have we learned that the field…

  • Steve Brusatte on the Dinosaurs That Survived the Asteroid

    May 28, 2026 · 33 min

    Birds are the only dinosaurs that survived the asteroid impact 66 million years ago — but not all birds did. In this episode, Steve Brusatte draws on the fossil record to explain which birds came through the extinction, and what set the…

  • Alec Brenner on When Tectonic Plates First Moved

    April 30, 2026 · 29 min

    A key development in the history of the early Earth is the formation of lithospheric plates that move independently of one another. In this episode, Brenner describes how he used paleomagnetic methods to detect relative motion between two…

  • Steve Jacobsen on Materials in Extreme Environments

    April 15, 2026 · 36 min

    Most of the material in the Earth and other planets exists under extremes of pressure and temperature quite unlike those we inhabit on the surface of the Earth. Steve Jacobsen is a mineral physicist who studies how rocks and minerals…

  • Esther Sumner on Turbidity Currents

    March 26, 2026 · 31 min

    Though turbidity currents are massive and frequent underwater events, we have rarely observed them directly. Esther Sumner is one of the few researchers who has. In the podcast, she describes what it's like to instrument an active…

  • Hal Levison on the Mission to Jupiter's Trojan Asteroids

    March 6, 2026 · 37 min

    A key question about the early history of the Solar System is whether the giant planets formed roughly at the distances from the Sun they presently occupy, or, as some theories predict, much closer to the Sun. The discovery of other solar…

  • Sara Pruss on the First Reef Builders

    February 11, 2026 · 23 min

    The first multicellular animals to build reefs lived in the Early Cambrian around the time of the Cambrian explosion. They were sponges called archaeocyaths. In the podcast, Sara Pruss suggests that the rise of the archaeocyaths fostered…

  • Michael Manga on Wet Eruptions

    January 20, 2026 · 40 min

    Water can have a dramatic effect on the style of an eruption. In the podcast, Michael Manga explains how the most powerful eruptions, such as the 2022 Hunga Tonga eruption, occur when hot magma comes into contact with water and suddenly…

About the show

What moves the continents, creates mountains, swallows up the sea floor, makes volcanoes erupt, triggers earthquakes, and imprints ancient climates into the rocks? Oliver Strimpel, a former astrophysicist and museum director asks leading Earth science researchers to divulge what they have discovered and how they did it.
