28. The map shows some of Earth's tectonic plate boundaries with the directions of plate motion indicated by arrows. Which location has high risk of earthquakes but low risk of volcanic activity?
Answer: B
Location B has high risk of earthquakes but low risk of volcanic activity.
Location B is characterized by tectonic activity that leads to frequent seismic events while not being associated with volcanic activity. This suggests that the tectonic plate boundaries in this area primarily involve lateral or compressional movements rather than subduction or rifting that typically generate volcanism.
A) A
Location A likely has both high seismic activity and volcanic risk, as it may be situated near a convergent or divergent boundary where both earthquakes and volcanoes are common. This disqualifies it as having a low risk of volcanic activity.
B) B
Location B is accurately identified as having a high risk of earthquakes but low risk of volcanic activity. This is consistent with geological settings where tectonic plates slide past each other, creating significant seismic hazards without the presence of magma that would lead to volcanism.
C) C
Location C may present a volcanic risk, possibly indicating it is near a subduction zone or a hotspot, which correlates to both earthquakes and volcanic activity. Therefore, it does not fit the criteria of having low volcanic risk.
D) D
Location D likely experiences either high earthquake and volcanic activity or low seismic activity, which does not align with the specific conditions described in the question. This means it cannot be the correct answer regarding the combination of high earthquake risk and low volcanic risk.
Conclusion
B is definitively the correct answer as it encapsulates the specific geological conditions of high seismic risk without volcanic activity. The other options either indicate a combination of risks or fail to meet the criteria outlined in the question.
