Transcript

  1. Earth’s Interior and Plate Tectonics<br />Earth’s Interior and Plate Tectonics<br />Weathering and Erosion<br />Physical Weathering<br />Evidence for Plate Tectonics<br />What is Earth’s Interior like<br />Chemical Weathering<br />Erosion<br />Transform Fault Boundaries<br />Earthquakes and Volcanoes<br />Minerals and Rocks<br />Plate Tectonics<br />Convergent Plate Boundaries<br />How old are Rocks<br />Divergent Plate Coundaries<br />What are Earthqua<br />Volcanoes<br />Structure and Origin of Rocks<br />
  2. Earthquakes and Volcanoes<br />Vocabulary<br />Focus – the area along a fault at which slippage first occurs, initiating an earthquake.<br />Epicenter – the point on Earth’s surface directly above the focus.<br />P waves – primary waves; the longitudinal waves generated by an earthquake<br />
  3. P waves<br />

  5. 2011 Japan Earthquake<br />http://www.youtube.com/watch?v=iQfdl7y-blE<br />http://www.youtube.com/watch?v=zfxlzyOXlic&feature=related<br />http://www.youtube.com/watch?v=TRDpTEjumdo&feature=related<br />http://www.youtube.com/watch?v=4GFLqsUexZ0<br />http://www.youtube.com/watch?v=nLUmQrKOyuk&feature=related<br />http://www.youtube.com/watch?v=1ikus_TEaGI&feature=related<br />http://www.youtube.com/watch?v=OdhfV-8dbCE&feature=related<br />http://www.youtube.com/watch?v=w3AdFjklR50&feature=relmfu<br />
  6. How volcanoes are formed http://www.youtube.com/watch?v=ANeH9W-HMPc&feature=related<br />
  7. A 1976 earthquake near Guatemala City shattered this bridge in Agua Caliente, cutting off the city’s main supply route to the Atlantic. The 7.5-magnitude quake killed more than 23,000 people and left thousands more injured and homeless.<br />
  8. A crane and several construction vehicles lay toppled on a fractured road in Kobe, Japan, after a 7.2-magnitude temblor shook the quake-prone country. The Great Hanshin Earthquake Disaster of 1995 was one of the worst in Japan’s history, killing 6,433 people and causing more than $100 billion in damages.<br />
  9. The San Andreas Fault scars Southern California’s Carrizo Plain like a battle wound. The 800-mile (1,300-kilometer) fault runs through western and southern California, dividing the Pacific and North American plates.<br />
  10. Workers position support beams to steady tilting homes in San Francisco's Marina District after a disastrous earthquake hit the city in 1989. The 7.1-magnitude earthquake buckled highways and bridges, crushed cars, and toppled homes and buildings throughout the city.<br />

  20. 17.2 Earthquakes and Volcanoes<br />Vocabulary<br />Focus<br />Epicenter<br />P waves<br />S waves<br />Surface waves<br />Seismology<br />Richter scale<br />vent<br />
  21. 17.2 Earthquakes and Volcanoes<br />Read: “Energy from earthquakes is transferred through Earth by waves” (p568-569)<br />Write on your cornell notes information on:<br />Longitudinal waves<br />Primary waves<br />Transverse waves<br />Secondary Waves<br />

  24. Mt. Pinatubo, Philippines<br />Mt. Pinatubo Crater Lake<br />
  25. Mt. Pinatubo, Philippines<br />Mt. Pinatubo Crater Lake<br />
  26. Mt. Pinatubo, Philippines<br />Mt. Pinatubo Days Before Eruption<br />
  27. Mt. Pinatubo, Philippines<br />Mt. Pinatubo: First Eruption<br />
  28. Mt. Pinatubo, Philippines<br />3 Minutes after first Eruption<br />
  29. Mt. Pinatubo, Philippines<br />5 Minutes after first Eruption<br />
  30. Mt. Pinatubo, Philippines<br />Mt. Pinatubo: 7 minutes after<br />
  31. Mt. Pinatubo, Philippines<br />Mt. Pinatubo: 10 minutes after<br />
  32. 17.2 Kind of Volcanoes<br />Shield Volcano<br />Magma rich in iron and magnesium<br />Very fluid<br />Lava flows great distances<br />Eruption mild<br />Eruption occur several times<br />Lava produces gently sloping mountain<br />
  33. 17.2 Kinds of Volcanoes<br />Composite Volcano<br />Made up of alternating layers of ash, cinders and lava<br />Magma is thicker<br /> Gases are trapped in the magma making explosive eruptions<br />Typically thousand meters high<br />Steeper cones than shield volcanoes<br />
  34. 17.2 Kinds of Volcanoes<br />Cinder Cone<br />Smallest and most abundant volcanoes<br />Tend to be active for a short time then become dormant<br />Vast quantities of ash and lava fall around vent that form the cone<br />Gas-trapped magma – explosive eruption<br />
