The ExPLORERR was built to go everywhere. That’s why this vehicle’s full name is: the Extremely Practical Land and Ocean Rover Exploring Remote Realms. And guess what? It has a recording studio built on-board! Good thing, because this episode was recorded while traveling up, up, up a mountain!

We discover some wildlife that lives at great heights as well as a rhyming ice cream salesman. Our pal and atmospheric scientist, Dr. Deanna Hence checks in to answer a popular question: if hot air rises, why is it so cold in the mountains? BRRRR! We also hear from NASA’s Dr. Dalia Kirschbaum, who has mountains of information about how mountains form.

Of course, there’s a fun Mystery Sound for you’re ears to explore! And lastly, but not leastly, our two new books came out today. Head to our books page to find out more about Road Trip Earth and Earth Friend Forever.
