Go to the Plate Type Effect on VolcanoesEarth Science GeoInquiryby Esri.
Step 7 Zoom in on California.
29.Describe the locations of the two plate tectonic boundariesfound in California.
Step 8 Zoom out so that you see the Pacific west coastof the United States from Washington state toCalifornia.
a. What plate tectonic boundary type caused the PacificNorthwest volcanoes? Tip: include whether the tectonic plates areoceanic or continental.
Step 9 Scroll to the north and west on the maps so thatAlaska and the Aleutian Islands are in view.
b. What plate tectonic boundary type created the AleutianIslands?
Step 10 Zoom out so that the Hawaiian Islands are inview.
c. Are the Hawaiian Islands found on a plate tectonicboundary?
Part E. Plate Tectonics Synthesis
Review the above information on the Earth’s interior,plate tectonic boundaries, and hotspots, and then answer thefollowing questions.
d. Why is it necessary to understand the layers of the Earth’sinterior in order to understand plate tectonic boundaries types andhotspots? Explain your response in at least three sentences.
e. Students often confuse the three plate tectonic boundarytypes (convergent, divergent, and transform) and hotspots. What arethe similarities and differences between these geologic features?Tip: consider which boundary types are associated with mountains,volcanoes, and earthquakes. Explain your response in at least threesentences.
