  • S01E01 Intro to Geology

    • April 9, 2026

    There’s no place like Earth—and we’ve got the planet’s spectacular, one-of-a-kind geology to thank for it. In this episode of Crash Course Geology, we’ll explore how geology touches our lives, helps us solve mysteries about the planet’s past and its future, and puts our world life in perspective.

  • S01E02 How did Earth form?

    • April 16, 2026

    What can a moon rock tell us about Earth’s distant past? All kinds of stuff! Like where its water came from, how it got its moon, and what its birth might have looked like. In this episode of Crash Course Geology, we’ll stroll down memory lane with the Earth’s baby book, and learn about some of the ways it might have formed.

  • S01E03 Earth's Crust and Mantle Explained

    • April 23, 2026

    Nobody has made it to the center of the Earth—but not for lack of trying. In this episode of Crash Course Geology, we’ll journey through the crust and mantle that make up ⅔ of our planet’s insides. We’ll uncover how these layers affect our lives on the surface, and how geologists discover more about them without traveling into Earth’s depths themselves.

  • S01E04 What’s at the center of the earth?

    • May 7, 2026

    The crust and the mantle are cool, but Earth’s real hero is its core, which helps protect us from all kinds of stuff. In this episode of Crash Course Geology, we’ll take a journey to the center of the Earth to meet our hero, the core.

  • S01E05 How Do Minerals Form?

    • May 14, 2026

    Minerals are amazing and they’re all around us, in the food we eat and even in our very bones. But what actually is a mineral? In this episode of Crash Course Geology, we’ll learn the basics of mineral identification and uncover the surprising connections between minerals and life itself.

  • S01E06 The Rock Episode

    • May 21, 2026

    Where do rocks come from? In this episode of Crash Course Geology, we’ll discover how the rock cycle transforms one type of rock into another, while recycling Earth’s materials over and over again.

  • S01E07 How Do Gems Form?

    • June 4, 2026

    For most of human history, one thing has been true – we LOVE shiny things. Gems are the crown jewels (pun intended) of geology, and for thousands of years, we’ve wanted to know all about them. In today’s episode of Crash Course Geology, we’ll explore some of those burning questions, like, what are they? Where do they come from? And are they actually that special?

  • S01E08 Where Do Diamonds Come From?

    • June 11, 2026

    Diamonds are a girl’s best friend. But they’re so much more than that. They’re sources of power, wealth, and conflict. They’re tickets into Earth’s deep, ancient past. (And they’re super duper cursed. Well, some of them. Maybe.) Join us to learn more about where these strange gems come from, and the hold they’ve had over us for thousands of years.

  • S01E09 How Water Shapes the Land

    • June 18, 2026

    Drop by drop, water has the power to break rock and create whole new landforms. But how? In this episode of Crash Course Geology, we’ll trace how the water cycle works and how this humble geological force sculpts the land as we know it—faster than you might think.

  • S01E10 What is Plate Tectonics

    • June 25, 2026

    A long, long time ago, Earth was home to one giant super continent. So, what happened? In this episode of Crash Course Geology, we’ll break down plate tectonics and how it shapes Earth’s past, present, and future.

  • S01E11 How Do Mountains Form?

    • July 9, 2026

    What can lift ocean creatures up to the top of Everest, bend rocks, cause earthquakes, and sink parts of continents under the sea? Join us on this week’s episode of Crash Course Geology as we investigate how some of the coolest geological forces around make mountains, faults, and may even one day turn Africa into a series of islands!
