Absolutely! Volcanoes are most common near the
boundaries of Earth's tectonic plates. At these
plate boundaries we find almost all of our
earthquakes. A dramatic example of this pattern
can be seen along the edge of the Pacific Plate
(which is dotted with volcanoes and lots of
earthquakes), which we call the "Ring of Fire."
The West coast of the U.S. is part the Ring of
Earthquakes and volcanoes along the Ring of
Fire can be explained by a process called
subduction. Subduction occurs when two tectonic
plates collide, and one of them dives below the
other into the upper mantle layer. The movement
of the "diving" plate produces earthquakes.
Volcanoes occur wherever magma (liquid rock
with some solid pieces) erupts onto the Earth's
surface, which happens in many places around the
world. In a subduction zone, for example, the
plate that is "diving" into the mantle can
partially melt and create magma. This magma rises
through the overlying crust and erupts as a
