Crust is destroyed at convergent boundaries Crust is destroyed at convergent boundaries. Crust is formed at divergent boundaries. Crust is neither destroyed or formed at transform boundaries.

Divergent boundaries move apart creating new crust.

Mid-ocean ridges form at divergent boundaries by pushing up seafloor.

Mid-ocean ridges are underwater mountain ranges that can form at a divergent boundary.

A rift valley is a gap at divergent boundaries where molten material rises to build new crust.

Rift valleys can occur in the ocean to create mid-ocean ridges or on continents to form volcanoes, lakes, or rivers.
