Explain why different volcano types have different eruption hazards. The plates move in response to intense pressure created underneath by the movement of currents carrying heat energy from the center of the planet to the surface. The water slightly reduces the melting point of the overlying rock, forming magma that can work its way to the surface—the spark of life to reawaken a slumbering volcano. The route includes viewing points like the Humboldt (La Orotava), Valle (Teide National Park) and Crucita (Corona Forestal) and can be combined with a tour of local wineries.This reward does mean trying the somewhat sulphurous flavours typical of the Canary Islands.
