Question
Which sentence supports the process of subduction?
- Continental crust is melting.
- Oceanic crust is forming
- Oceanic crust is subducting under the less dense oceanic crust.
- Volcanic islands are forming due to subduction.
The correct answer is: Oceanic crust is subducting under the less dense oceanic crust.
At subduction zones, older portions of a plate are more likely to subduct because they are thicker and colder than the warm mantle material underneath them. Hence, the Oceanic crust is subducting under the less dense oceanic crust.
