In this episode, we tackle a listener question regarding planning a geology trip for students.  Both Chris and Jesse have quite a bit of experience in planning and executing field excursions for students.  We believe that seeing geology in the field is one of the most powerful learning opportunities for students of all levels.  In our discussion, we talk about the difficulties in convincing the higher-ups that this is actually a good idea.  We also get into some of the struggles in finding excellent teacher resources.  In the end, we get a little philosophical on the importance of getting comfortable with not having all of the answers.  We think that sometimes it's important for students to know that instructors don't know it all and together we can perhaps think about things different and come to new conclusions.  We hope you enjoy. We now have a live Mobile App for iOS and Android.

Join us as we have the honor of interviewing Dr. John Douglas.  Jesse and Chris have been following his research on how the Grand Canyon was actually formed for some time.  We have recently finished our audio-visual book on the Grand Canyon (Link above) and we have a chapter dedicated to the actual cutting of the Canyon.  The answer to this question has been elusive, but there are a few leading theories.  John has been leading the way on the Spillover Theory as a mechanism for carving the young Canyon.  It's a great geologic discussion and we hope you enjoy.We now have a live Mobile App for iOS and Android.

The idea for this episode came from the comment section of a social media post.  It has it's roots in one of the biggest misconceptions in Geology and also Geochronology.  The comment was about radio-carbon dating and how it's been "proven" to be unreliable.  In this episode, Jesse and Chris have a discussion about the "toolbox" for geochronoligists and we also spend a lot of time talking about Uranium to Lead decay.  We hope you enjoy.We now have a live Mobile App for iOS and Android.

In charge of the Nations Rock Collection.  That's a pretty sweet job description.  Join us as we have the honor of interviewing Dr. Mike Ackerson.  In this episode, we certainly get into some detail about igneous petrology.  Mike and Jesse are good friends and have spent some time discussing things that introductory geology classes take for granted.  For instance, there are some questions on the formation of granite.  This might seem ridiculous because this topic is covered in any intro level geology class, but there are some problems.We also talk philosophically about geoscience education and scientific research.  In all, this discussion spans too many areas to summarize here.  We hope you enjoy!  We now have a live Mobile App for iOS and Android.

Today, Jesse and Chris discuss the geology of Nickel - The Devil’s Metal.  Surprisingly, Earth’s core has a high percentage of Nickel - 10 to 20% of the core is nickel.  We allow ourselves the luxury of getting into the details on nickel and why the core has so much.  Of all the metals we’ve discussed on the podcast, the geology of nickel is the most complicated.  In addition to discussing the geologic settings that form or concentrate nickel, we also spend some time discussing the history and uses.  We hope you enjoy the discussion.We now have a live Mobile App for iOS and Android.

Today, we have the another great interview - Dr. Anji Shah.   She works for the USGS and has done a lot of work on heavy-mineral sands and critical elements.  In this discussion, we talk about the paleo-environment that could concentrate critical minerals in heavy sands.  Dr. Shah also tells us how "airborn geophysics" is important in looking for mineral deposits over huge areas that are often canopy covered.  We hope you enjoy!We now have a live Mobile App for iOS and Android.

In this episode, Jesse and Chris discuss the geology of asbestos. Really, we cover all things related - history, past uses (some of which are mind boggling),  health issues, and of course the mineralogy. If you want the datail, this episode is for you. Jesse goes off the deep end a little as he nerds out on some geochemistry.  We hope you enjoy. We now have a live Mobile App for iOS and Android.

Dr. Adam Simon joins PlanetGeo to discuss many topics.  One of the most interesting topics of discussion is the copper dilemma facing the world.  If we want to transition to green energy like Electric Vehicles, we will face a shortage of copper.  Dr. Simon describes Copper as the artery of a green transition.   However, he's done the math and it doesn't add up.  There isn't enough to make the transition.  We hope you enjoy this extremely informative and entertaining interview.We now have a live Mobile App for iOS and Android.

Today, Chris and Jesse once again revisit the topic of Bowen's Reaction Series.  We've never approached the topic in such a before.  The heart of our discussion centers around 1- What is Bowen's Reaction Series? and 2- How do we approach this highly idealized concept in an introductory class.  How rocks really crystallize in a geologic setting is far more complex than Bowen's Reaction Series.  This can lead to confusion when students progress in their geologic studies when they learn that Bowen's is the whole story (or even the correct story).  We hope you enjoy this technical and philosophical discussion.We now have a live Mobile App for iOS and Android.

Today is our latest episode in our series on climate.  Jesse and Chris discuss the meaning of "Hard Water".  Chris and Jesse both have hard water at our houses and we talk about how that happens.  We wrap up this episode by talking about how the topic of hard water fits into our series and climate.  We hope you enjoy!We now have a live Mobile App for iOS and Android.

Join us as we interview Dr. Steph Mrozek.  Steph is an economic geologist with interests in interests in skarn and porphyry deposits and geochemistry applied to mineral exploration.  In our interview, the discussion turns to degrees in geoscience and educational pursuits.  We’ve received a number of questions from listeners about what degree to pursue and how far to go.  Steph offers unique perspectives on this topic that many of our listeners will find very useful. Then our discussion turns to a niche geologic topic - Skarns.  Jesse and I learned a ton.  We (Jesse and I) have some personal experience with Skarn deposits, but Steph is the expert in the room for sure.In the end, we have an in depth discussion about a career in exploration and mining geology.  This episode has so much to offer.  Listeners will learn about a topic that many aren’t familiar with and will also learn about the life and times of an exploration geologist.  We know you will enjoy this episode.We now have a live Mobile App for iOS and Android.

Join Chris and Jesse as we tackle questions about the Grand Canyon.  A 4th grade class, Bronx Little School, reached out in a letter with a list of fantastic questions.  We knew right away we wanted to make an episode about this.  These questions, and our responses, provide a great introduction to the geology of The Grand Canyon.  Below are the questions - asked and answered:1. How deep is the Grand Canyon?2- Why are the rocks orange, red, and black?  How were the rocks made?3- Why is the Grand Canyon so steep?4- How old is each layer in the Grand Canyon?5- They didn't ask this question, but Jesse and I couldn't resist.  So we posed the question: How did the Grand Canyon get cut?  Maybe one of these awesome students will find the answer.We hope you all enjoy learning a little more about one of the Natural Wonders of the World.  CheersWe now have a live Mobile App for iOS and Android.

Today, we re-visit one our earliest episodes that we recorded when this whole thing began.  We've decided to do a small series on Earth's climate and feel that this is the best kickoff point for that topic.  We begin by discussing the forgotten history of climate science.  This is important because we have known the physics of greenhouse gases for over 200 years.  This pre-dates excessive fossil fuel consumption and any thought of political ideology around climate change.  We talk about following the radiation from the sun and the change that takes place when certain photons are absorbed at the Earth's surface.  That change in energy is what gets absorbed by the various greenhouse gases.  We round out the discussion by talking about several of the important gases and why carbon dioxide is the "big dog" in the discussion.  We hope you enjoy!We now have a live Mobile App for iOS and Android.
