Question

The map shows oceanic tectonic plates in the southeastern pacific ocean. what is likely happening at the boundary between the nazca plate and the south american plate?

Answer 1

At the boundary between the Nazca Plate and the South American Plate, subduction is likely happening, causing the formation of the Andes Mountains and resulting in earthquakes and volcanic activity.

Step-by-step explanation:

At the boundary between the Nazca Plate and the South American Plate in the southeastern Pacific Ocean, a process called subduction is likely happening. Subduction occurs when one tectonic plate moves beneath another, causing the oceanic crust of the Nazca Plate to sink below the continental crust of the South American Plate. This subduction process is responsible for the formation of the Andes Mountains along the western margin of South America. The subduction zone is also characterized by frequent earthquakes and volcanic activity.
