[Rockhounds] Mysterious volcanoes

[Kreigh Tomaszewski]

In this episode of Life's Little Mysteries, we'll take a closer look at
some explosive mysteries that originate deep inside the Earth — volcanoes.

How do scientists know when a volcano is about to erupt, what would happen
if the Yellowstone supervolcano erupted, and what would Earth look like if
every volcano on the planet erupted at once? Listen to Life's Little
Mysteries 5: Mysterious Volcanoes to find out!

We'll also hear about ancient volcanoes that may have helped the global
rise of mammals around 65 million years ago, and a volcanologist will
explain how scientists monitor volcanoes to better predict eruptions.
