What is sand? What’s it made from, and how does it get from where it’s made to the beaches and sand dunes that surround many of our shores? On this album, Dr Dave McGarvie of The Open University takes us on a visit to Cornwall to follow grains of sand on their journey from the high moorland to the sea shore. Back in the lab, he demonstrates some techniques for looking in detail at samples of sand. The album draws on material originally created to support The Open University course Exploring ...

After an unexpected hiatus, hosts Jane and Ellen return with a down and dirty episode about soil. Jane reveals her childhood experiences with a DIY mud spa before digging into the agricultural and geological definitions for soil. They discuss the four main components of soil: inorganics, organics, water, and air or gas. They talk about how to ident…
 
Hosts Jane and Ellen finish each other’s… sandwiches in this “Frozen” episode about glaciers. Glaciers are a body of moving ice that has been formed on land by the compaction and recrystallization of snow. They take forms like valley, ice sheet, or outlet, because, really, who’s going to tell them not to. Learn why glaciers are more likely to form …
 
We’re devoting this episode to the season’s most dreaded stocking stuffer, coal. Travel back in time to the Paleozoic era, where coal starts as rotten plants. Add heat, pressure, and time, and quick as a wink from old Saint Nick - you’ve got coal! And like Santa’s naughty or nice list, learn how coal is graded into four types: lignite, sub bitumino…
 
What’s big and deadly, and travels faster than a jet plane? It’s a tsunami. Hosts Jane and Ellen explain how ocean waves become tsunamis. They talk about the basic properties of waves, and the differences between tidal waves and tsunamis. They also talk about some famous tsunamis. (Spoiler alert - don’t expect a happy ending.) Sources: Introduction…
 
Jane interrupts our scheduled discussion of tsunamis to take us on a Magic Schoolbus-like field trip to Missouri’s Elephant Rocks State Park. Along the way we learn a bit about Missouri’s history, and culture (mort importantly the three Bs of St. Louis: Beer, Blues, and Barbeque). We also learn cool stuff about the geology of this Gateway to the We…
 
So you think you’ve got problems… imagine what happens when the earth’s crust is under stress and strain. Learn about the forces that cause earthquakes, and how structural geologists measure them. This episode is guaranteed to give you the shimmy shakes. (Guarantee not legally enforceable, but it’s still pretty cool.) Our main source for this episo…
 
In this episode, we learn that some rocks have more than a killer attitude — they’re actually deadly. Lock all the doors and turn down the lights as hosts Jane and Ellen tell spooktacular tales about the many horrible ways rocks can kill you. Whatever you do, don’t listen to this episode…alone! Bwahaha! ☠️ Our sources for this episode are: Killer C…
 
In this episode, we learn about all things volcano: where they’re found, how they’re formed, and even how volcanologists use them for cooking. We also learn that the Tectonic Plate struggle is real, and that volcanoes are some of the evidence. Crank up the A/C and get ready to go with the lava flow in this sizzling episode. Our main source for this…
 
This episode talks about geomorphology, the study of the Earth’s landforms. This includes the physical makeup of the earth’s crust, the movement of the pieces that make up the Earth (plate tectonics), and the origin and evolution of topographic (and bathymetric) features created by physical and chemical processes, and operating at or near the earth…
 
We explore the final frontier, starting with the Big Bang Theory, followed by the creation of our solar system, then the humble beginnings of our planet, including a rough encounter with the moon about 4.5 billion years ago, and ending with a discussion of what Earth looked like in its nascent state. Our main source for this episode is Earth: An In…
 
Welcome to the world of geology! In our first episode of It’s Sedimentary, My Dear, we introduce ourselves, talk about the different types of rocks and minerals, and tell you our favorites. We think you’ll dig it! Our main sources for this episode are: Mineralogy and Optical Mineralogy (1st ed.), by Dyar, Gunter, & Tasa Earth: An Introduction to Ph…
 
Are curious about your home — your home planet, that is? Welcome to the podcast that explains it all, It’s Sedimentary, My Dear. Every other week, hosts Jane and Ellen “dig deep” into the secrets buried in the rocks and minerals that make up planet Earth. Whether you want to learn more about geology, geomorphology, and climatology, or just enjoy te…
