Ring Of Fire Volcanoes Quiz – Fuji, Krakatoa and St Helens

The Ring of Fire is a horseshoe of volcanoes and earthquake zones around the Pacific. Most of its volcanoes form where ocean plates sink beneath other plates, melting rock that rises as magma.

Famous eruptions include Krakatoa in 1883, whose roar was heard thousands of kilometers away, and Mount St. Helens in 1980. Pinatubo in 1991 cooled the planet for a while, and Tambora in 1815 caused the year without a summer.

Mount Fuji last erupted in 1707, and Ojos del Salado in the Andes is the world's highest volcano. Hawaii's volcanoes are different, rising over a hotspot in the middle of the Pacific Plate.
