The Image Is a Similar Cross-Section to the One Developed

question 118

Multiple Choice

The image is a similar cross-section to the one developed by a USGS geologist after the large 1964 Alaska earthquake, showing how uplift from the earthquake was explained by thrusting of the continent over the oceanic crust. How did this support the development of the theory of plate tectonics?

• A) The motion indicated is the same as an ocean-continent convergent plate boundary with subduction, as is predicted for this area by plate tectonics.
• B) The motion indicated is similar to what would be predicted by a divergent plate boundary in plate tectonics.
• C) The USGS explanation from 1964 was so completely wrong that scientists knew they needed to develop a new theory to explain crustal motion.
• D) The motion is transform plate boundary motion, which is the main type of boundary plate tectonics dictates for the southern coast of Alaska.
