Where Do Volcanoes Form?

Answer

Volcanoes usually form deep within the earth when rock from the mantle melts and gathers enough pressure to move towards the surface. The force that brings the rock to the surface leads to an eruption that is often disruptive.

Most of the 600-plus active volcanoes on Earth are associated with the boundaries of the tectonic plates.
They are especially common in subduction zones, which occur when one plate dips beneath another.
Volcanoes form around the edges of the Earth's plates. They are found in many places, but they also follow a pattern. An eruption or other volcanic activity happens when the plates shift, when there is a hot spot or when one plate lowers below another.
