About this episode

The episode explores the rock cycle through the adventures of Walter the Rock with insights from geoscientist Dr. Lina Pérez-Angel.

Ever wondered if rocks can melt like cheese, explode out of volcanoes, or travel to the bottom of the ocean? Join Rob, Hank, and special cohost Kenji as we follow the incredible adventure of Walter the Rock through the rock cycle with geoscientist Dr. Lina Pérez-Angel from Brown University and the Geological Society of America. Together, we discover how rocks form, melt into magma, cool into igneous rocks, break into sediments, and transform deep underground over millions of years. ➡️ This episode is possible thanks to the Geological Society of America ➡️ Learn more about Dr. Lina’s science communication work with GeoChat: ⁠ LINK Orbit Family Conversation Starters!
