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.

In this episode, we're back with the fabulous Dr. Rachel Phillips, also known as Geo Girl on YouTube, diving into part two of our intriguing Q&A session. This time, we cover listener questions about early Earth geology, the moon-forming impact, geochemistry, and much more. Spoiler alert: we journey into the cosmic and tectonic weeds, so grab your scientific hats as we ponder if the moon-forming whammy kickstarted plate tectonics and its broader implications on our planet! The center of our discussion revolves around a burning question: Did the moon-forming impact trigger plate tectonics? From vigorous debates on early Earth’s behavior to the staggering differences between Earth and its 'toxic twin' Venus, we leave no stone unturned—or unmelted. Dr. Phillips and Jesse examine the evidence, debunk some age-old myths (bye-bye, late heavy bombardment), and think about how a cataclysmic impact billions of years ago might have reset our planetary clock. Oh, and don't get us started on whether Earth or moon rocks are older—trust us, it's complicated. As we approach the end of our cosmic conversation, we speculate about how such colossal impacts might have played a role in developing early life on Earth. Did these monumental collisions cook up the perfect conditions for life's early proliferation, or did they serve as the ultimate reset button? Join us on this epic journey through time, magma oceans, and cratered landscapes.
