VOLCANO SONG

THE VOLCANO SONG


What's it like when volcanoes blow?
This is something you ought to know:
pressure buiLds without interruption
and then explodes in a volcanic eruption.

When volcanoes erupt, here's what they do:
the pressure makes ash and lava spew.
Boulders can get thrown through the air.
Move back -don't stand and stare!

It's letting off pressure.
It's not going to wait.
It is going to get to that balance state
where forces are equal: equilibrium.
Then the pressure starts building up again.


What's it like when volcanoes blow?
This is something you ought to know:
pressure buiLds without interruption
and then explodes in a volcanic eruption.


Remember this from your science classes?
A volcano's forces are magma and gases
the underground pressure gets too high
and the volcano blows up in the sky.


What's it like when volcanoes blow?
This is something you ought to know:
pressure buiLds without interruption
and then explodes in a volcanic eruption.
