5. The transfer of heat by the circulation or movement of heated of gas or liquid.
6. A long narrow ditch. Very deep.
7. Plate moving apart from each other.
8. Plate that slides beneath another plate.
9. The sudden release of energy from the earth's crust.
13. High energy wave caused by an earthquake,volcano, landslide or other natural events.

1. plates theory States that earth's crust is made up of plates that moves alongside each other.
2. The process of a plate going underneath another plate.
3. spreading Formation of new oceanic crust through volcanic activity and gradually move away from ridge.
4. drift States that parts of the earth's crust slowly drift on the liquid core.
6. Plates sliding pass each other.
10. plate The sub-layer of the earth's crust that move,float and sometimes fracture.
11. boundaries Areas where two or more plates meet.
