Bernhard Steinberger on Whether Hotspots Are Fixed
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. Fo...

Sonia Tikoo on the Moon's Magnetic Field
We have known for decades that the Moon once generated a strong magnetic field — comparable in strength to Earth's — throughout the period f...
Steve Brusatte on the Dinosaurs That Survived the Asteroid
Birds are the only dinosaurs that survived the asteroid impact 66 million years ago — but not all birds did. In this episode, Steve Brusatte...
Alec Brenner on When Tectonic Plates First Moved
A key development in the history of the early Earth is the formation of lithospheric plates that move independently of one another. In this...
Materials in Extreme Environments
Most of the material in the Earth and other planets exists under extremes of pressure and temperature quite unlike those we inhabit on the s...
Esther Sumner on Turbidity Currents
Though turbidity currents are massive and frequent underwater events, we have rarely observed them directly. Esther Sumner is one of the few...
Hal Levison on the Mission to Jupiter's Trojan Asteroids
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 pr...
Sara Pruss on the First Reef Builders
The first multicellular animals to build reefs lived in the Early Cambrian around the time of the Cambrian explosion. They were sponges call...
Michael Manga on Wet Eruptions
Water can have a dramatic effect on the style of an eruption. In the podcast, Michael Manga explains how the most powerful eruptions, such a...
Carina Hoorn on the Evolution of the Amazon Basin
The Amazon Basin is the most biodiverse region on Earth, being the home of one in five of all bird species, one in five of all fish species,...
Anat Shahar on What Makes a Planet Habitable
Over 6,000 exoplanets have now been found, and the number is constantly rising. This has galvanized research into whether one of them might...
Keith Klepeis on How Plutons Form
Plutons are bodies of igneous rock that crystallize from magma at depth below the Earth’s surface. But even though this magma never makes it...
Tom Herring on High-Precision Geodesy
There are three main types of geodetic measurement systems — satellite-based systems such as GPS, very long baseline interferometry (VLBI),...
Jiří Žák on the Orogenies that Shaped Central Europe
In this episode, Jiří Žák describes the two main orogenies whose remnants figure prominently in central European geology: the Cadomian oroge...
Claudio Faccenna on the Dynamics of Subduction Zones
Subduction zones can be very long-lived, persisting for tens of even hundreds of millions of years. During that time they rarely stay still,...
Cees Van Staal on the Origin of the Appalachians
In the podcast, Cees Van Staal tells us about the Paleozoic tectonic events that led to the formation of the Appalachians. The events are cl...
Andreas Fichtner on the Frontiers of Seismic Imaging
In previous episodes of Geology Bites , Barbara Romanowicz gave an introduction to seismic tomography and Ana Fereira talked about using sei...
Renée Tamblyn on the Origin of Continents
When the Earth formed, it was covered by a hot magma ocean. So when and how did thick, silica-rich continental lithosphere form? Were the fi...
Folarin Kolawole on Continental Rifting
From East Africa to southwest USA, many regions of the Earth’s continental lithosphere are rifting. We see evidence of past rifting along th...
Mike Hudec on Salt Tectonics
Most of Earth’s salt is dissolved in the oceans. But there is also a significant amount of solid salt among continental rocks. And because o...
