Plate Tectonics

2. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate
5. Theory that parts of Earth's crust slowly drift atop a liquid core
8. Region where 2(or more)tectonic plates move apart
10. Region where 2(or more) tectonic plates move toward one another and collide
11. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas
12. High energy wave
13. the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side

1. deep rift valley formed by the divergent boundary
3. Zone in Earth's crust along which rocks slide past each other
4. Location where tectonic plates meet
5. Theory that Earth's crust is divided into 12 large plates
6. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
7. A large chunk of Earth's crust
9. a long narrow steep-sided depression in the earth's oceanic crust
