• The mantle increases in size.
• Pressure in the crust increases.
• Pressure in the crust decreases.

Name the boundary

A subduction zone is formed...

In which type of boundary do the plates go away from each other?

• convergent
• normal
• divergent
• transform

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

• convergent
• transform
• strike-slip

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...

• a fault
• a mid-ocean ridge
• a rift valley
• a trench

Continental crust and continental crust come toward each other at a convergent plate boundary.  This will likely form...

• a trench
• mountains
• a subduction zone
• new land

Oceanic crust slides underneath continental crust at a convergent boundary. This is called a...
