One of the greatest challenges for most people when it comes to understanding geology is the concept of time. When our lives are measured in minutes, hours, and days, what does 3-7 million years even mean? Or 4 billion years? Explore the conventions of geologic time during this week’s installment.
About the series: Join the Geology Gents, Gavin and Graham, for weekly conversations about rocks live on Facebook. Each week we’ll explore a different geologic topic, from Santa Cruz formations to tips for being a more effective rockhound. Graham Edwards and Gavin Piccione are PhD candidates in geochronology with the Department of Earth and Planetary Sciences at UC Santa Cruz.
Submit your questions ahead of time on Facebook or by emailing firstname.lastname@example.org, or during the program live on Facebook. Feel free to include pictures of rocks you’d like identified! Pro-tip: the better the picture, the better the ID.
