Web Research topic 5

I’m trying to study for my Geology course and I need some help to understand this question.


  1. Select one (1) of the following questions for research. Research sources of information can include Internet sources, books, articles, videos, etc. Every explanation must include a picture/diagram that helps detail your answer.
    • How does Plate Tectonic Theory explain the difference between Mount Saint Helen’s-type eruption (explosive) and a Hawaiian-type eruption (effusive)?
      • Explain the difference between an explosive eruption that builds a stratovolcano and an effusive eruption that builds a shield volcano.
      • Provide a picture/diagram that displays the difference.
      • Explain the difference in tectonic environment of formation for each (convergent plate boundary vs. hot spot).
    • How do geophysicists use paleomagnetism to test the Plate Tectonic Theory?
      • How and when was paleomagnetism discovered?
      • Explain the details of paleomagnetism.
      • Explain how paleomagnetism discovery led to acceptance of Plate Tectonic Theory and provide a diagram or link to a animation/visualization.
    • What type of plate tectonic activity is currently taking place in the Red Sea and East Africa?
      • Discuss the processes that occur at this type of Plate Tectonic boundary.
      • Make a predictions as to what this area will look like 50,000,000 years in the future based on this Tectonic Plate movement.
      • Provide a diagram or link to a animation/visualization.
    • Will California really “fall into the ocean?”
      • Discuss the Tectonic Activity taking place at this type of plate boundary.
      • What will ultimately be the fate of California in the next 50 million years?
      • Provide a diagram or link to a animation/visualization.
    • Who was J. Tuzo Wilson?
      • What is a Wilson cycle?
      • Given an example of a complete cycle.
      • Provide a diagram or link to a animation/visualization
