Some places on Earth are especially likely to have volcanic activity. Most of these sites mirror where Earth’s tectonic plates come together and move apart.
The Pacific region hosts the largest concentration of volcanoes, called the “ring of fire.” There are also volcanoes in the Mediterranean Sea, Africa, and the Atlantic Ocean.
Throughout the world there are places called hotspots. Scientists have determined that these areas, while not necessarily residing over the edges of tectonic plates, show accelerated magma movement and heat.
They are also likely places for volcanoes to erupt.
