  • How to Identify Rocks - Rerelease
    Jan 1 2026

    Welcome back to Planet Geo, the podcast where we delve into the wonders of our planet's geology, how it works, and why it matters. In this episode, part three of our holiday re-release series, we’re breaking down the basics of rock identification and collection techniques. Chris and I tackle the popular question: how do you identify rocks? We provide a general strategy perfect for budding rock hounds and outdoor enthusiasts. Plus, stay tuned for new episodes and exciting modifications coming to Planet Geo’s sixth year, including deep dives with Dr. Rachel Phillips and geology news segments with Dr. Josh Davies. Follow us on social media and check out our Camp Geo mobile app for tons of free, cool content!


    Today's discussion dives into the nitty-gritty of rock identification. We walk through our methods, distinguishing between sedimentary, metamorphic, and igneous rocks, and share handy tips like carrying a magnifying lens, a little acid bottle, and a hammer to reveal a rock’s true identity.


    We also chat about reliable resources like the Roadside Geology series to help you understand the geology of specific areas. We emphasize the importance of breaking rocks open to see fresh surfaces and narrow down your identification process methodically. Remember, even seasoned geologists take samples back to the lab for further analysis! Finally, we talk about the value of curiosity and the learning process. Whether it’s being the 'annoying student' who asks all the questions or participating in practical exercises like visiting a gravel pit, there’s a lot to gain from hands-on experience. We encourage you to do some research before your next trip and embrace the joy of discovery. If you have more questions or need help, hit us up at Planet Geo Cast on Gmail or on social media. Happy rock hunting and may your geological inquiries always rock!
