Last year, when I was teaching plate tectonics, we culminated our unit by watching Dante's Peak with Pierce Brosnan and the lead from Terminator, tearing apart all the science.

The Cascade mountain had runny, fast moving basalt lava, like how Hawaiian volcanoes flow. Andesite mountains do produce ash, it is a *lot* thicker than in the movie, and it is more like mud (hence, a lot of mud flows). Hard to breathe.

Boiling the couple in the hot springs? Water itself does not turn colors to be red hot! And when it does get that hot, it like, produces clouds of steam as it boils...

And the truck would like, totally be on fire if it drove over lava, fer shur, fer shur...

But great fun!
