Episode 47 We dare you to say ‘Ice Aged Ice Sheets’ five times fast. But first, in this episode, the GotR Gang dive into all things Glaciers, brrrr. Glaciers and Glaciation, generally speaking, covers the formation, features, effects, and causes of glaciation events on Earth. Ice sheets and alpine glaciers are described, including their movement and erosional features and landforms. Glacial deposits will be examined, including a discussion of the features created by till and stratified drift. Other effects are worthy of discussion, including crustal subsidence and rebound, sea level changes, alterations to streams and stream valleys, and the formation of proglacial and pluvial lakes. However, there is not enough time in one episode to bring you all the fun facts about glaciers. Remember, if you fall down a crevasse, the good news is you will only fall 50 meters. The bad news is that you will fall 50 meters. Between the bars of our main discussion, we present to you another Mineral Minute, then close things out with special guest Joe Guzman of Space Poets to promote his Psychedelic Panther Music Fest during this week’s That Freaking Rocks! Until next time remember to… Be Cool, Stay Tuned, & Keep It On The Rocks --- Support this podcast: https://podcasters.spotify.com/pod/show/geology-on-the-rocks/support

Episode 45 A season finale! This episode closes out season 4 with a dang bang! We finally get around to answering some of the questions we have received, such as jobs and career paths in the geosciences, what our favorite geologic structures are, identifying minerals in the field, types of rocks you might encounter in various depositional settings. Carly even shares with us a story about what happens when you give her a geology fact. Between the bars of our main discussion we present another mineral minute sponsored by the hydrated phosphouranlyte mineral, Dewindtite. Until next season, stay tuned, be cool, and keep it on the rocks! --- Support this podcast: https://podcasters.spotify.com/pod/show/geology-on-the-rocks/support

Episode 37 After a crazy September, we are finally back back! This episode is a follow-up to the Speleology Special, and we dive a bit deeper into the fascinating world of caves. We begin our discussion with the controls of cave temperatures – latitude and altitude, among other variables. Fun fact, the temperatures at lower depths in caves can be regarded as “fossil” temperatures. An example of this is seen in the Pierre St. Martin Cave in France. This cave is measured to have a depth of 1,474 meters, and by doing a little bit of maths, temperatures near the bottom of the cave presumably reflect the average annual temperature of the region as it was nearly 40,000 years ago! Mind. Blown. We then focus on relative humidity, air currents, barometric changes, chimney & reverse-chimney effects that all lead to the blowing cave phenomenon. On the back half, we walk our way through how early cave scientists studied the breath of caves to help better understand the mysteries of the underground abyss. We then have a little discussion about the formation of caves in Texas and marvel at the epic names of the rooms get, using Natural Bridge Caverns as an example. As always, between the bars of our main discussion, we present to you another Mineral Minute, sponsored by Tyuyamunite, and we close things out with another That Freaking Rocks. Until next time, we remind you to be cool, stay tuned, and keep it on the rocks! --- Support this podcast: https://podcasters.spotify.com/pod/show/geology-on-the-rocks/support
