1. ability to cause change 2. region of a longitudinal wave where the particles
are farthest apart
3. travels through empty space and through matter
4. disturbance that transfers energy but not matter
5. highest point on a transverse wave
6. lowest point on a transverse wave
7. region of a longitudinal wave where the particles
in the medium are closest together
8. makes particles in a medium move parallel to the
direction that the wave is traveling
9. a material in which a mechanical wave travels
10. when the disturbance is perpendicular to the direction the
wave travels
11. travels only through matter

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust. 

Ihave no idea what the answer is
