Question

Marina has been onboard the research vessel Gustavo, off the coast of Chile, for several weeks now. She is measuring the depth of a very deep trench in the ocean that runs parallel to the coastline. In the distance, she notes a great mountain range on the mainland. Suddenly, she is notified that a submarine earthquake just occurred below the trench, generating a tsunami. As Marina puts on her lifejacket, she recalls the type of plate boundary nearby that led to the trench formation. Based on the description given, what type of plate boundary is near the area Marina has been studying? rift valley transform divergent convergent

Answer 1

Here ya go!

Step-by-step explanation:

Answer 2

convergent

Step-by-step explanation:

Convergent limits are the type of boundary defined by the movement of the plates in the direction of approach, that is, when two tectonic plates move in a convergent direction, colliding between them frontally. In these cases, the dense plate dips under the lightest one, being incorporated into the warm material and fluid of the mantle.

A tsunami can be generated when the boundaries of converging tectonic plates move. For this reason, we can conclude that the type of board boundary that is close to the area that Marina has been studying is a convergent limite.
