Question

What is a subduction zone?

a. A place where one plate is pushed down under another, such that it melts into the mantle
b. A place where two plates collide and mountains form
c. A place where hot material from the core rises through the mantle
d. A place where the seafloor is spreading

Answer 1

A. a place where one plate is pushed down under another such that is melts down into the mantle.

Step-by-step explanation:

Subduction is a type of convergent boundary that occurs when one plate is denser than another and therefore sinks below it. This occurs when an oceanic plate converges with a continental plate. The oceanic plate is denser than the continental plate above it, and it sinks, forming a trench. As the plate sinks, the rock is melted and is often forced back up through volcanoes that appear along the shoreline. The Mariana's Trench is a famous example of a geological feature formed at a subduction zone.

Answer 2
