Question

At which point is crust neither created nor destroyed?

island chain
mid-ocean ridge
divergent boundary
transform boundary

Answer 1

The point at which crust is neither created nor destroyed is the **transform boundary**. At transform boundaries, tectonic plates slide past each other horizontally, resulting in no new crust being formed or existing crust being destroyed. In contrast, at mid-ocean ridges (a type of divergent boundary), new crust is created, and at convergent boundaries, crust can be destroyed.
