The document discusses different types of volcanoes. It explains that volcanoes are mountains that usually erupt gas, ash, and molten rock. Inside volcanoes is hot magma, which becomes lava when it reaches the surface. Some volcanoes are active and always erupting, while others are dormant or extinct. The document provides examples of specific volcanoes like Mount Vesuvius, which destroyed Pompeii in 79 AD, and Mount St. Helens, which killed 57 people during its 1980 eruption. It also briefly describes volcanoes like Teide, Etna, Nevado de Ruiz, and Krakatoa.

8. A STORY FROM
THE PAST

9. Vesuvius is an excint volcano in Italy. Its very famous because there was a
terrible eruption in 79 A.D. We know about the eruption from very old lettlers.
One afternoon the people from Pompeii heard a loud noise. They looked up
and saw a cloud of ash shooting out of the top of Mount Vesuvius . Soon
after that, failling rocks started hitting the town. People ran out of their
houses, but they couldn't breathe. There were huge clouds of ash and gas.
By the evening, thousands of people were dead.
The next day, lots of mud and ash covered the town. It hardened into rock
and covered Pompeii.
Pompeii was a lost city.
People forgot about Pompeii for 1,500 years.
