So, we’ve got a map here. Do you guys know what the numbers ... to explore what a mountain is and how they’re formed by tectonic plate movement. Mountains typically rise more than 600 metres ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another ...
