Transcript

  • 1. VOLCANOES AND EARTH QUAKES
  • 2. VOLCANOES AND EARTH QUAKES Earthquakes are when parts of the earth suddenly break away from each other and move. This can sometimes result in an earthquake or tsunamis. Most scientists believe that the crust of the earth is not a solid rock like the inside or core is. They believe that there are plates in the ground that suddenly break off and move with no warnings. The plates are on top of what we call the mantle. They are constantly moving all the time at a micro slow rate. When two plates move away from each other they create a volcano which is illustrated in the next picture.
  • 3. VOLCANOES AND EARTH QUAKES
  • 4. VOLCANOES AND EARTH QUAKES This picture illustrates what the impact of a strong earth quake can do to major towns and establishments. (The earth quake in Japan.)
  • 5. VOLCANOES AND EARTH QUAKES We have lots of mass plates all over the world. We call them Plate Tectonics. This picture will help illustrate them for you.
  • 6. VOLCANOES AND EARTH QUAKES Plate tectonics are thought to be the reason for the continents moving. After some time the continents moved to be linked together like they are know but before then they may been one whole continent, this is what scientists call a pangaea.
  • 7. VOLCANOES AND EARTH QUAKES The continents seem to all fit together like a puzzle. The Eastern coast of South America fits together flawlessly on a map along with the Western coast of Africa. If you slightly rotate North America and put it together with Europe and Asia it fits together perfectly. This coincidence is illustrated on the next page.
  • 8. VOLCANOES AND EARTH QUAKES
  • 9. VOLCANOES AND EARTH QUAKES Volcanoes are another thing on Earth’s surface. They are formed and triggered by plate movement. Volcanoes are a big opening in the earth, like an open wound is to your body. When we have an earth quake the juice inside the volcano (called magma) shoots out. The magma is a very hot liquid in the earth. Its powers have destroyed towns and cities. The magma rises because of the gasses that are in it. The erupted magma is called lava and when it cools it creates a certain rock. Eventually the lava builds up and makes the volcano appear very big.
  • 10. VOLCANOES AND EARTH QUAKES
  • 11. VOLCANOES AND EARTH QUAKES St. Pierre was a famous volcano eruption that covered the hole ancient city during the 20th century. This happened on May 8,1902. The eruption happened slightly before 8:00 a.m. completely covering the city and all living organisms with it. Many died in the cathedral because they where at morning mass for Ascension Day. Ascensions Day was a newly formed Christian Holiday. 29,000 residents where killed. Many of the residents are preserved in the lava as rocks. They are literally frozen in the act of hiding from the volcano. There belongings are also preserved in the hardened lava. Along with food as well.
  • 12. VOLCANOES AND EARTH QUAKES This is a dog that has been pasteurized in the hardened lava. The people are also preserved like this as well.
  • 13. VOLCANOES AND EARTH QUAKES These are some food remains.
  • 14. VOLCANOES AND EARTH QUAKES As you can know see volcanoes and earth quakes can be very destructive. They have destroyed major towns and cities. There impact and strength can be astounding. The destruction they cause is astonishing. They can also cause a lot more damage then just themselves, often times other natural disasters, like tsunamis, can happen after them. Earth quakes for example changed the face of the world, and they can be devastating.
