In which type of boundary do the plates come toward each other?

• convergent
• transform
• strike-slip
• divergent

Oceanic plates separate from each other at a divergent plate boundary at the bottom of the ocean.  Magma comes up and cools between the plates, forming...

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

• Crust is destroyed at the same time it is created
• New crust is underwater where it sinks
• New crust breaks more easily than old crust
