课件43张PPT。The Power of NatureUnit 51.How is a volcano formed?The rocks under the earth becomes hotter and hotter and erupted from the mountain.Volcano form when hot material from below rises and leaks into the crust(地壳）. The hot material called magma, rising from lower ground,gathers in a reservoir called the magma chamber. Eventually, but not always, the magma erupts onto the surface and form lava. Strong earthquakes accompany rising lava, and the volcano may swell（膨胀） just before an eruption. gasliquidsolidLava(熔岩)vapour水蒸气,

What do you know about volcano? extinct volcanoHaleakala Crater, the largest dormant volcano in the world,Maui, Hawaii.
active/live volcanoCatastrophic eruption of Mount Vesuvius on August 24 of 79 AD, buried the towns of Herculaneum and Pompeii in Italy. This mountain has erupted more than 50 times since the eruption in 79 AD, when it buried Pompeii and its sister city, Herculaneum.
After Pompeii was buried and lost to history, the volcano continued to erupt every 100 years until about 1037 A.D., when it entered a 600-year period of quiescence.
In 1631, the volcano killed an additional 4000 unsuspecting inhabitants. Mount Vesuvius ? Mount Kilauea
It is Hawaii's youngest and yet most active volcano. It first erupted in January 1983 and has been active ever since.
