Cutting the Grand Canyon - Dr. John Douglass
April 11, 2024 10:00 - 1 hour - 50.6 MBJoin 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 yo...
Uranium and the Start of the Earth? - How Geochronology Works
April 04, 2024 10:00 - 37 minutes - 25.7 MBThe 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. The...
The History of Granite - Dr. Mike Ackerson
March 28, 2024 10:00 - 1 hour - 56.6 MBIn 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 leve...
The Devil's Metal - The Geology of Nickel
March 21, 2024 10:00 - 48 minutes - 33.4 MBToday, 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 a...
Geology From Above - Dr. Anji Shah
March 14, 2024 10:00 - 1 hour - 42.3 MBToday, 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. There you c...

We Just Don't Have Enough - Prof. Adam Simon
February 22, 2024 11:00 - 1 hour - 51.6 MBDr. 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...
How Do Rocks Really Crystallize?
February 15, 2024 11:00 - 47 minutes - 32.9 MBToday, 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 Bo...
Why is Water "Hard"?
February 08, 2024 11:00 - 29 minutes - 19.9 MBToday is our latest episode in our series on climate. Jesse and Chris discuss the meaning of "Hard Water".

The Epic Earthlings Grand Canyon Questions - Answered!
January 25, 2024 11:00 - 40 minutes - 27.8 MBJoin 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...
And...We're Back! The Greenhouse Effect
January 18, 2024 11:00 - 36 minutes - 24.9 MBToday, 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 fo...

Slow Carbon - The Rock Carbon Cycle
November 16, 2023 11:00 - 37 minutes - 25.9 MBToday, Jesse and Chris tackle the topic of the Slow Carbon Cycle. We've been talking about this for a while now. This is a very complicate cycle that involves many variables. In this episode, we work through some scenarios such as the Himalayan uplift and plug them into the Carbon Cycle. It's a little bit of mental gymnastics. The ingredients for the Carbon Cycle to operate are freshly exposed rock, water (both in the oceans and the atmosphere), and plate tectonics. If one of these var...
The Infiltration Game - Soils and Flooding
November 09, 2023 11:00 - 45 minutes - 31 MBIn this episode, we tackle the issue of infiltration capacity. The idea came to us in the form of a listener question due to recent events. Infiltration capacity is simply a way of describing the ability of soil and regolith to soak up water during storm events that drop a lot of rain in a short period of time. There are several variables that must be accounted for in describing the infiltration capacity for a given area. Humans have also caused a significant change related to this topic...

Are You Karsty? Sinkholes and Karst
September 21, 2023 10:00 - 36 minutes - 25 MBToday, Jesse and Chris discuss the distinction between sinkholes and karst topography. There is a surprisingly large portion of the U.S. that has potential to be affected by karst. It is also extremely important as a source of drinking water. We also discuss the distinction between the technical definition of karst and what is called pseudokarst. Below is a link to the article and diagram we allude to in the show. We hope you enjoy. https://www.frontiersin.org/articles/10.3389/feart.20...
Geoscience is EVEN MORE Important
September 14, 2023 10:00 - 37 minutes - 26 MBWe get a bit reflective today and discuss the importance of Geoscience to society - and how it has changed in the last three years. Jesse recently went to a conference on economic mining and came away newly excited. If the world is going to make the energy transition, certain elements are critical in allowing us to meet that demand. Today, we talk about the issues surrounding the energy transition and how geoscientists are playing an integral role (and will continue to do so) in society. ...

Petrification
August 24, 2023 10:00 - 32 minutes - 22.1 MBToday, we are talking about the process of making petrified wood. Basically, wood has to be quickly buried in a wet setting where the water is also saturated in certain minerals - usually silica. Also, there must be little oxygen present or oxidation reactions have to occur to use up all of the available oxygen. This prevents the wood from getting eaten by decomposers. We will also get into the geologic settings where this is likely to occur. Finally, we talk a little about how we come ...
Creepy Soil
August 17, 2023 10:00 - 19 minutes - 13.7 MBToday, we talk about all things soil creep. Have you ever been on a steep slope and seen bent or curved trees, slanted fence posts, slanted headstones or signs? Look closely and you can often see the surface has a rippled appearance. Soil Creep is a form of what we call Mass Wasting in Geology. Mud flows, avalanche, and rockfall are also examples of Mass Wasting. Creep just happens very, very slowly. Join us and learn how this fascinating process works! We now have a live Mobile App f...
Stream Drainage Patterns
August 10, 2023 10:00 - 34 minutes - 23.6 MBJust as in so many aspects of the way the world works, geology determines the drainage patterns (or watershed) of rivers.

Plants and Meanders - How to Read a Geoscience Paper
May 25, 2023 10:00 - 34 minutes - 23.8 MBHere is a link to the paper we discuss in this episode: In this episode, we talk about meandering streams. Why don't rivers flow in straight paths? As soon as a river flattens out, it begins to meander. It’s these meanders that manage the energy of the water. How? They really do 2 things: 1- they increase the resistance (physics) and 2- they decrease the gradient. Essentially, the river is changing itself to minimize the energy it expends to maintain a state of equilibrium. We also g...
Not All Who Meander Are Lost - Meandering Streams
May 18, 2023 10:00 - 40 minutes - 27.8 MBIn this episode, we talk about meandering streams. Why don't rivers flow in straight paths? As soon as a river flattens out, it begins to meander. It’s these meanders that manage the energy of the water. How? They really do 2 things: 1- they increase the resistance (physics) and 2- they decrease the gradient.

The Geology of Oakland - Andrew Alden author of Deep Oakland
May 11, 2023 10:00 - 50 minutes - 35 MBIn this episode, we interview author Andrew Alden. He wrote Deep Oakland: How Geology Shaped a City. This book is a wonderful read and it offers a unique lens in which to view a city. Jesse and Chris both think that this idea should become a series - much like the Roadside Geology series. Andrew talks about his motivation for the monumental task. The 1989 Loma Prieta earthquake that shook the city of San Francisco and kind of woke him up to the idea. Deep Oakland is an intricate stor...
