Oh, wow, oh, oh, wow, oh, wow, oh, man.

Oh, my.

And so, you're listening to The Science of Everything podcast, episode 124, Volcanoes.

I'm your host, James Fodor.

Now, in this episode, we are, as the name indicates, going to talk about volcanoes.

In particular, I'm going to talk about the nature and causes of volcanoes, the different types of volcanic eruptions,

and the related different types of volcanoes that are formed by different types of volcanic eruptions and the related different types of

volcanoes that are formed by different types of eruptions. Then we'll discuss a little bit about

some of the different volcanic landforms that can be formed as a result of volcanic activity

and conclude by talking about a few case studies of particularly important or well-known volcanic

eruptions.

The recommended pre-listening for this episode is episode 111 on plate tectonics,

which will give a bit of a background about some of the underlying mechanisms that power

volcanoes ultimately. So I'm not really going to be talking about the plate tectonics side of it

too much. I'll just make a few references here

and there to diverging and converging plate boundaries and such. But in this episode, what we're

really going to focus on are volcanoes as such and that specific phenomenon. All right, so

that being said, let's make a start and talk about sort of what is a volcano and what causes volcanic eruptions.

Many people are familiar with volcanoes but perhaps haven't thought about exactly how to define one.

A volcano is defined as a rupture in the crust of Earth or another planetary object,

but here we're just going to be focusing on Earth.

And this rupture allows hot lava, ash and gases to escape from a chamber below the surface.
