Lab: Plate Boundaries and Movement

Question 9 • PARTA - EVP: PGCPS BIOGEOCHEM CR (FALL2026) - 798113

Which events most likely occurred at the boundary between the South American Plate and the Nazca Plate? Check all that apply.

Answer
A
destruction of crust
B
creation of rift valleys
C
formation of a trench
D
separation of two plates
E
subduction of one plate

Explanation

The Nazca Plate moves beneath the South American Plate at a convergent boundary. This subduction destroys oceanic crust and forms a deep ocean trench along the boundary. Rift valleys and separation of plates are associated with divergent boundaries, so choices B and D do not apply.
