PlanetGeo: The Geology Podcast – Détails, épisodes et analyse

In this episode, we delve into the fascinating concept of hypsometry and its applications in understanding Earth's topography. We start with a light-hearted email from a listener, but quickly transition into discussing the principles of hypsometric curves. We break down how these curves provide insights into the distribution and stability of Earth's crust, oceanic and continental. Through our conversation, we explore the role of plate tectonics and erosion in shaping the Earth's surface, making this complex scientific topic accessible and engaging, even touching on classroom applications and educational tools.

In this episode we engage in a lively conversation with Dr. Rachel Phillips, popularly known as GeoGirl on YouTube. Rachel shares her journey from resisting geology despite her geologist parents, to embracing it due to a chemistry class in college. She discusses her PhD research on ancient ocean chemistry and reveals her recent focus on geoscience education and communication through an NSF fellowship. With insights into her popular YouTube channel, survey findings on geoscience misconceptions, and upcoming projects, Rachel's passion for leveraging digital media to foster interest in geology shines through. Don't miss this engaging discussion that delves into the realms of geoscience, education, and innovative outreach!

In this podcast episode, Dr. Jesse Reimink and Chris Bolhuis delve into part two of their discussion on Earth's oldest rocks, specifically the Acasta Gneiss. They explore the origin, complex history, and significance of these ancient rocks, including insights from Dr. Reimink's PhD research which suggests an Icelandic rather than subduction zone setting for their formation. The conversation covers the challenges of studying such remote and deformed rocks, the iterative process of geological fieldwork, and the ongoing debates about their exact ages. They also discuss the logistical difficulties of accessing the Acasta Gneiss and the commercialization of samples.

One day, I (Chris) walked into class and announced that we were beginning plate tectonics.  I was so excited to begin teaching this content.  The response from my students was not at all what I expected.  They let me know that they had all the plate tectonics they could handle in middle school and there wasn't anything left to learn.  They knew the 3 basic types of plate boundaries (kind of) - divergent, convergent, and the T-one.  I then started asking deeper level questions that tested their ability to apply this huge theory to make sense of the world around them.

During lunch that day, I began writing a series of questions about the unifying theory of plate tectonics.  Needless to say, their understanding was skin deep and that's totally Okay.  I wanted to show that we can take a basic understanding and use it to make so much more sense of our world. 

That "event" gave me the idea to do a series on PlanetGeo covering a deep dive into plate tectonics.  Jesse was not easy to convince.  He felt like it was too massive.  Anyway, I won and here comes the series.  In this episode, we answer the following questions:
1.  How does plate tectonics explain the formation of basalt?
2. How does plate tectonics explain the formation of andesite?
3. How does plate tectonics explain the formation of granite?

We hope you enjoy!

Today, we get to interview author Kevin Krajick.  Below is a small sample of his credentials and accolades.

• Senior Editor Science News Communications, Columbia Climate School
• Author at State of the Planet
• Work has been featured in National Geographic, Newsweek, The New Yorker, Science, Smithsonian Mag, etc
• Two time Winner of the American Geophysical Union's Walter Sullivan Award - excellence in science journalism
• Finalist for the National Magazine Award for Public Service

We were interested in interviewing Kevin because of his book on Searching for diamonds in the Northwest Territories in Canada.  This is a place near and dear to Jesse's heart because he does a lot of research up there.  The book is exceptional and reads more like a novel mainly because of two featured individuals: Chuck Fipke and Stewart (Stu) Blusson.  They are both Canadian geologists, prospectors, businessmen, helicopter pilot, etc.  Check the link below for the book.

In addition to writing this book, Kevin is a writer for the Columbia Climate School (https://news.climate.columbia.edu/).  He has written on an impressive array of topic from climate, Earth science, and society.  

We hope you enjoy this interesting interview.  Cheers.

In this episode, we tackle the confusing industry of "granite" countertops.  It's confusing because it seems as though all rock countertops are called "granite".  However, to a geologist, granite is a very specific type of rock and only a small percentage of countertops are actually granite.  

There are maybe 5 or so major rock types that are all found in the "granite" countertop category.  We spend some time talking about each major type:

• Marble - this might be named accurately actually in most places.  Is it very white with no distinct grains showing?  Then it is probably marble.  Especially if it has long dark wavys streaks
• Granite - there is some real granite in there!  Does it have pink, white, grey, and a few black flecks in it?  Most of the grains are smaller than your fingernail? Then it may actually be granite.  Can be white - no pink, too.  Has to have some black flecks and some gray too. 
• Pegmatite - Does it have really really large grains?  The size of your finger?  Grey, white, black, with crazy textures in between them?  It might be a pegmatite
• Schist/gneiss - does it have a definite texture and pattern in one direction?  Are their little waves of light and dark wavy patterns? Are there big deep purple garnets in it or blue flakes?  What about dark and light bands with an overall darker color?  It could be gneiss or schist. 
• Conglomerate - does it have a bunch of round or oblong grains in it of a variety of colors?  Could be a conglomerate - these are spectacular. 
• There are others to be sure.  These are just the most common.

We also talk about another type that is growing in popularity - Quartz counters.  They aren't actually quartz though.  We like this option a lot because it's a green product.  No rock was mined for the specific purpose of making countertops.  Quartz countertops are a form of engineered stone, made from ground-up particles of stone bound together with plastic resins.  About 90% of the material is Crushed up waste granite, marble, and natural stone or recycled industrial wastes such as ceramic, silica, glass, mirrors, etc.

We hope you enjoy!

In this episode, we dive into a very important topic that will play an increasing role in the climate change crisis.  Carbon (CO2) capture and storage (CCS) is a big geoscience problem, and a possible solution to climate change.  But, we need to understand these two terms well - it’s all about making rocks!

The oceans capture carbon for us, but we want to help this process along.  In order to do that, we need to find ways to concentrate the Carbon because it's in such a low overall concentration in the atmosphere.  We discuss some of the ways companies are trying to speed up the concentration process.

Once the Carbon is captured, we need to find ways to store it.  Rocks such as limestone in the ocean is a natural way for Carbon storage.  Again, we discuss some of the creative ways companies are researching to effectively store the captured carbon.  We hope you enjoy our discussion on the very important topic.

This is a link to the video of the Quick Clay Slide at Dissa video Dr. Alley references. This shows what can also happen to a glacier when it loses it's toe-hold as described in this episode.

Dr. Richard Alley is a renowned glaciologist and paleoclimate scientist.  He is also widely regarded as one of the best professors at Penn State University.  Below is a list of his impressive credentials:

• National Academy of Sciences
• Foreign Member of the Royal Society
• Evan Pugh University Professorship
• Penn State’s top teaching award
• Presidential Young Investigator Award
• Earth - the Operator’s Manual - 
• Briefed senators, international legislators, and a sitting US Vice President
• Published an unbelievable >310 papers/books/etc

Join us as we discuss climate change, glaciers, and sea level.  Much of his current research is on a Western Antarctic glacier called Thwaites Glacier.  It's been dubbed the doomsday glacier because of its likely impact on sea level.  Alley is a gifted speaker and uses  incredible analogies to paint a vivid picture. 

Another big part of the discussion is how Carbon is the thermostat control knob for our atmosphere.  We hope you enjoy the discussion.  We did!
