Across:

3.	When the earth's tectonic plates move
4.	The vent on the earth's surface through which magma and gases are expelled
7.	the process by which Earth's crust breaks apart; can occur within continental crust or oceanic crust
9.	the layer of the upper mantle composed of low-density rock matterial that is semiplastic,like putty.
10.	At a convergent convergent boundary where an ocean meets a continent, the ocean dives under.
11.	What type of process is created by a divergent boundary.
12.	where two plates are moving apart, magma comes up to create new crust

Down:

1.	the theory that explains how large pieces of the lithosphere, called plates, move and change shape the topography of the earth.
2.	an underwater chain of mountains.
5.	boundary between two colliding plates, often associated with mountain building ocean trenches and volcanic islands
6.	the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
8.	boundary between two plates that are sliding past each other.
