Volcanoes have been erupting on Earth for BILLIONS of years, and they’re still creating new landscapes today! Volcanoes can seem mysterious and scary, but people all over the world have learned to live in close proximity to active volcanoes. Today we answer questions you’ve sent us about how they form, how they erupt, what magma/lava is, and how volcanologists work to predict when they might erupt. Our guest is Freysteinn Sigmundsson, a volcanologist and professor at the University of Iceland.

If you could be a superhero, what would you want your superpower to be–and what would you call yourself? That’s what we asked kids for this special end-of-year episode, and we got some amazing answers! Some kids want to fly. Some want to go back in time. One wants to be able to draw everything perfectly the first time. And a surprising number of kids want a super ability to do math! Stories about humans with special abilities have been around for as long as humans have been telling stories. But the word superhero is only about 120 years old. The first known use of the word was in 1899, but the term became more mainstream in 1930s comic books and movies. Now, superheroes are all over the pages of books and both the small and big screen.
