According to the notes, which of these is NOT a common trigger for tsunamis?

AUnderwater landslides

BLarge underwater volcanic activity

CMeteorite impacts in the ocean

DGradual sea level rise

Answer:

D. Gradual sea level rise

Read Explanation:

According to general scientific understanding (as the previous "notes" were from our conversation about the meaning of the word 'tsunami', not a document about tsunami triggers), gradual sea level rise is NOT a common trigger for tsunamis.

Common triggers include:

  • Earthquakes: Especially large underwater earthquakes that cause significant vertical displacement of the seafloor.

  • Underwater Landslides: Large slides of material on the seafloor.

  • Volcanic Eruptions: Particularly those that cause caldera collapse or displace large amounts of water.

  • Meteorite Impacts: Though very rare, a large impact in the ocean could generate a tsunami.
