Earth is a unique planet, restless and dynamic, where continents shift and clash, volcanoes erupt, and glaciers grow and recede. There are titanic forces that are constantly at work, leaving behind a trail of geological mysteries.

Three quarters of Earth's volcanoes are situated here, and 90 percent of all earthquakes also occur along this line. Learn more about this Ring of Fire from the following documentary by Best List.
