What it is about

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.

Ed Brook on the Oldest Antarctic Ice

2026-11-06 · 29 min · Season 1, episode 130

Tiny bubbles of air trapped in Antarctic ice are samples of the ancient atmosphere itself, one of the few direct records of how greenhouse gases and climate have changed together. Until recently, the oldest ice known…
Tony Watts on the Mechanics of Tectonic Plates

2026-10-15 · 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…
Torgeir Andersen on Ultrahigh-Pressure Metamorphism

2026-10-02 · 28 min · Season 1, episode 128

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

2026-08-27 · 34 min · Season 1, episode 127

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…
Bernhard Steinberger on Whether Hotspots Are Fixed

2026-07-16 · 29 min · Season 1, episode 126

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…
Sonia Tikoo on the Moon's Magnetic Field

2026-06-27 · 33 min · Season 1, episode 125

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…
Steve Brusatte on the Dinosaurs That Survived the Asteroid

2026-05-28 · 33 min · Season 1, episode 124

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,…
Alec Brenner on When Tectonic Plates First Moved

2026-04-30 · 29 min · Season 1, episode 123

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…
Steve Jacobsen on Materials in Extreme Environments

2026-04-15 · 36 min · Season 1, episode 122

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…
Esther Sumner on Turbidity Currents

2026-03-26 · 31 min · Season 1, episode 120

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…
