The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates. The eastern section of the ring is the result of the Nazca Plate and the Cocos Plate being subducted beneath the westward-moving South American Plate. The Cocos Plate is being subducted beneath the Caribbean Plate, in Central America. A portion of the Pacific Plate and the small Juan de Fuca Plate are being subducted beneath the North American Plate. Along the northern portion, the northwestward-moving

Volcanoes form when two plates meet and one subducts underneath the other. They thus form along most plate boundaries; the Ring of Fire is an example of this. The study of volcanoes along plate boundaries has shown a correlation between eruptions and climate.

The leading idea, based on volcanic eruptions, is that sulfur dioxide released from volcanoes has a major effect
