To determine the correct geologic event occurring at a plate boundary, we first need to identify the type of boundary presented in the diagram. Based on the options you’ve provided:
- **A** refers to a convergent oceanic-oceanic plate boundary and associated volcanism, which is typical in regions where one oceanic plate subducts beneath another, forming volcanic islands.
- **B** refers to a convergent oceanic-continental plate boundary, which typically results in subduction of the oceanic plate beneath the continental plate, leading to earthquakes and volcanic activity.
- **C** refers to a divergent oceanic-oceanic plate boundary, characterized by sea-floor spreading, where two oceanic plates pull apart, allowing magma to rise and create new oceanic crust.
- **D** refers to a convergent continental-continental plate boundary, which generally results in mountain building as these two continental plates push against each other without subducting.
Without the exact diagram, I can’t assess which type is shown, but you could use the characteristics outlined to match against the diagram for your answer.
If the boundary shown is indeed a convergent oceanic-continental boundary, it would be reasonable to predict earthquakes as a significant event because this type of boundary is known for intense tectonic activity, including both earthquakes and volcanism. Conversely, if it shows a convergent oceanic-oceanic boundary, volcanism would be the expected situation. If it is divergent, then sea-floor spreading is the event to predict.
To summarize, if it’s:
- **Convergent oceanic-oceanic**: Option **A** (volcano)
- **Convergent oceanic-continental**: Option **B** (earthquake)
- **Divergent oceanic-oceanic**: Option **C** (sea floor spreading)
- **Convergent continental-continental**: Option **D** (mountain building)
Choose the appropriate option based on the type of boundary depicted in the diagram.
- **A** refers to a convergent oceanic-oceanic plate boundary and associated volcanism, which is typical in regions where one oceanic plate subducts beneath another, forming volcanic islands.
- **B** refers to a convergent oceanic-continental plate boundary, which typically results in subduction of the oceanic plate beneath the continental plate, leading to earthquakes and volcanic activity.
