2. =a supercontinent comprising all the continental crust of the earth
4. waves = are waves of energy that travel through the Earth's layers
5. =the rigid outer part of the earth, consisting of the crust and upper mantle.
6. tectonics =a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
8. =the transfer of heat energy
9. waves of energy that travel through the Earth's layers
10. =the continuous physical force exerted on or against an object by something in contact
14. boundary = is known as a destructive plate boundary, wich is an actively deforming region where two tectonic plates or fragments of lithosphere move toward one another and collide.
15. =the crust is the outermost solid shell
16. =the energy transmitted in this way, as heat, light
17. boundary = is a linear feature that exists between two tectonic plates that are moving away from each other

1. = a layer in the interior of Earth or another planet
3. = below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
7. spreading = a process that occurs at mid-ocean ridges
11. = the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity
12. core = one of the Earth's liquid layer
13. core =is a primarily solid ball
