  1. VOLCANOES DEFINITION WHERE THEY ARE FOUND RING OF FIRE

  2. VOLCANOES • A volcano is one of the most spectacular natural shows on the earth. • The fiery blasts of molten rock are brighter than fireworks and much louder. • The heat is intense, and massive clouds of choking gas and ash are often spewed out. This material all comes from the mantle, the molten zone beneath the earths crust. • Volcanoes are actively changing the face of the earth, either by building up new mountain peaks or blasting them away. • Volcanoes occur where molten magma is able to break through the thing crust.

  4. VOLCANO • From the picture before you can see that pressure from below pushes the magma upward, causing the volcano to mount higher and higher. • Extreme volcanic blasts happen when the ‘pipe’ connecting the mantle to the surface becomes blocked with hardened material. • The intense pressure of rising magma and gases can actually rip away the top of the mountain.

  6. WHERE ARE VOLCANOES FOUND • Volcanoes usually occur along the edges of the plates. You learned that some plates are being dragged toward on another by currents in the mantle below. • When two plates collide, the ocean plate is dragged underneath the bigger continental plate. • The end of the plate melts as it is pulled into the hot mantle, then the melted material finds it way back to the surface through cracks.
