A divergent boundary occurs where plates ....

• Pull apart

• Come together

• Slide past each other

• subducting

How is it possible for new crust to be formed without increasing the surface area of the Earth?

• Crust is recycled in subduction zones at the same time it is created at mid-ocean ridges

• New crust is underwater where it sinks

• New crust breaks more easily than old crust

• The oldest crust just breaks apart as the plates move
