Question

Why do volcanoes and

earthquakes occur along the
Ring of Fire? Think about:
• tectonic plate movement
• movement of magma

Answer 1

The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above.
