Question

multiple choice 1 point
the diagram above is of a subduction zone. the reason for its formation is due to:

• gravity differences between crustal plates
• friction differences between crustal plates
• temperature differences between crustal plates
• density differences between crustal plates

Explanation:

Subduction zones form when a denser tectonic plate (typically an oceanic plate) sinks beneath a less dense plate (continental or less dense oceanic plate). This process is driven by the density contrast between the two plates, as denser material is pulled downward into the mantle.

Answer:

density differences between crustal plates
