The Ring of Fire

The Ring of Fire is a huge ring that goes around the Pacific Ocean. It is not really a ring you can see. It is an area where many volcanoes and earthquakes happen. Countries like Japan, Chile, and the United States sit along it.

Why So Many Volcanoes

Earth's surface is made of big pieces called tectonic plates. These plates bump and slide against each other along the Ring of Fire. When they move, magma can push up and form volcanoes. The ground can also shake, causing earthquakes.

About 75 percent of the world's volcanoes are in the Ring of Fire. Mount Fuji in Japan and Mount St. Helens in the United States are on it. Many earthquakes happen here every year. Some cause big tsunamis in the ocean.
