Question

A team of geologists is studying the boundary between two tectonic plates: the Nazca Plate and the South American Plate. They find that the Nazca Plate is moving underneath the South American Plate,
causing frequent earthquakes and forming a range of tall mountains along the western edge of South America.

Which type of plate boundary is described in this scenario, and what major geological process is occurring?

(1 point)

O Divergent boundary; plates are sliding past each other and forming faults.

O Convergent boundary; one plate is subducting beneath another, forming mountains.

O Transform boundary; plates are moving away from each other, forming volcanoes.

Convergent boundary; plates are moving apart and creating new ocean crust

Answer 1

Convergent boundary; one plate is subducting beneath another, forming mountains.

(Explanation: the Nazca Plate is subducting under the South American Plate, causing earthquakes and building the Andes.)
