What is the theory of plate tectonics?

• Earth’s outer layer is made up of large, moving pieces called plates

• Cracks in the Earth's crust cause volcanoes

A region, known as the Ring of Fire, follows the border of the Pacific Ocean basin. Why do so many earthquakes and volcanoes occur in this region?

• Transform boundaries completely surround this region of the Pacific Ocean

• Only powerful convergent plates are located along the Ring of Fire.

• Two plates are diverging in the center of the Pacific Ocean basin.

• Numerous tectonic plate boundaries are located along the edges of this region.
