What are the main factors that determine the location of volcanoes?

The main factors that determine the location of volcanoes are tectonic plate boundaries, stretching and thinning of the crust's plates, and hotspot volcanism. Signup and view all the answers

What is hotspot volcanism and give an example of a hotspot?

Hotspot volcanism is when volcanoes form away from plate boundaries due to upwelling diapirs from the core-mantle boundary. An example of a hotspot is the Hawaiian hotspot. Signup and view all the answers
