Lab 6 Discussion Questions 1.
Looking at the earthquakes you have plotted on the map, do they appear to occur randomly over Earth’s surface, or in isolated or specific regions? Explain. Is there a pattern?
While the locations of the earthquakes are all over the map, most of them happen on islands or near Asia and Australia. 2.
If such a pattern does exist, could you use. It to determine where high-risk Earthquake zones are located? Name three of these high-risk zones. Yes, you could use it to determine where high-risk Earthquake zones are located. Three of these high-risk zones include along the rim of the Pacific Ocean, the Mid-Ocean Ridges, and the Eurasian-Melanesian Mountain Belt. 3.
From your map, can you determine if there is any connection between the Earthquakes and volcanoes appearing in the same location? Support your answer with an example from the map. Yes, you can determine if there is a connection between the Earthquakes and volcanoes appearing in the same location. On my world map, volcanoes appear around earthquakes of high magnitudes. 4.
Do you see any relationship between the Earthquakes, the volcanic activity, and the position of the tectonic plates? No, I do not see any relationship between the Earthquakes, the volcanic activity, and the position of the tectonic plates. 5.
Looking at the different types of plate boundaries (divergent, convergent, and transform), what type of crustal activity (volcanoes, earthquakes) do you expect at each?
Support your answer with specific examples. The crustal activity that occurs at a divergent plate boundary includes shallow earthquakes and volcanic activity as a result of two plates moving away from each other. The Mid-Atlantic Ridge is a good example of this. At this location, the North American and Eurasian plates are moving apart from each other, which created the oceanic ridges. The crustal activity that results from a convergent plate boundary is like a divergent. It can include volcanic eruption. The Pacific Ring of Fire is a good example of this. Transform plate boundaries produce earthquakes mainly. An example of this is the San Andreas Fault in California. 6.
Are there any specific trends you notice with regards to the type of plate boundary, and the depth of the Earthquake, or Richter magnitude? Give some specific examples to support your correlations
Some trends I have noticed include divergent plate boundaries being associated with shallow earthquakes. This means that the plate boundary can be associated with Earthquakes of low depth.
