We love getting questions about mining, minerals and geology! We were asked why volcanoes often form along tectonic plate boundaries:
The Earth’s surface is made up of a dozen large tectonic plates and a number of smaller ones.

These plates move imperceptibly - a few centimetres per year - and over the course of millions of years continents and oceans move and change shape. The plates pulling apart cause fractures or deep rifts in the Earth’s crust, both on land and under the sea...

...and plates colliding with each other form mountain ranges and new islands as the rock is forced upwards. It’s this powerful tectonic activity that results in so many volcanoes at plate boundaries.
