Energy of Earth

The heart of the Earth is extremely hot and it contains huge quantities of thermal energy. The clearest manifestation is represented by volcano eruptions: molten rock (the lava) manages to come out from the deepest areas of the earth through the craters of a volcano and it flows downstream burning everything it encounters, because of the extremely high temperatures that it reaches. In the picture you can see an eruption of the volcano Stromboli, on an island in southern Italy. Because of its frequent and intense activity, the ancient Greeks called the Stromboli volcano “the lighthouse” of the Mediterranean sea. (copyright CORBIS)
