German meteorologist Alfred Wegener is often credited as the first to develop a theory of plate tectonics, in the form of continental drift. Scientists discovered later that Pangea fragmented early in the Jurassic Period. The heat source is thought to be the decay of radioactive elements. How this convection propels the plates is poorly understood. Some geologists argue that upwelling magma at spreading centres pushes the plates, whereas others argue that the weight of a portion of a subducting plate one that is forced beneath another may pull the rest of the plate along. The Ring of Fire is a long horseshoe-shaped earthquake-prone belt of volcanoes and tectonic plate boundaries that fringes the Pacific Ocean basin. For much of its 40,km 24,mile length, the belt follows chains of island arcs such as Tonga and Vanuatu , the Indonesian archipelago , the Philippines , Japan , the Kuril Islands , and the Aleutians , as well as other arc-shaped features, such as the western coast of North America and the Andes Mountains.
