Question

at which point is crust neither created nor destroyed?
island chain
mid - ocean ridge
divergent boundary
transform boundary

Explanation:

• Island chains form from volcanic activity at subduction zones (crust is destroyed here).
• Mid-ocean ridges are divergent boundaries where new crust is created.
• Divergent boundaries are where tectonic plates move apart, creating new crust.
• Transform boundaries are where tectonic plates slide past each other horizontally, so no crust is created or destroyed.

Answer:

transform boundary
