Question

unit exam - earth systems
subduction zone, characterized by the sinking of one
plate into the earths mantle. one of the most iconic
features of oceanic - oceanic convergence is the formation
of deep oceanic trenches. exemplified by the mariana
trench, one of the deepest points on earths surface, these
subduction zones generate intense geological activity,
including the melting of crust, and contribute to the
dynamic processes that shape our planets seafloors.

what is a geological example of an oceanic -
oceanic convergent boundary?
andes mountains
hawaiian islands
mariana trench

Explanation:

The text explicitly states that the Mariana Trench is an example of a geological feature formed at an oceanic - oceanic convergent boundary. The Andes Mountains are formed at an oceanic - continental convergent boundary. The Hawaiian Islands are formed due to hotspot activity in the middle of a tectonic plate, not at a convergent boundary.

Answer:

C. Mariana Trench
