9. / the layer of hot, solid material between Earth's crust and core.
10. Drift / hypothesis that the continents slowly move across Earth's surface
13. / soft layer of the mantle which the lithosphere floats on.
15. core / this part is the molten part of the Earth's core.

18. / a plate boundary where two plates move away from each other
19. / the layer of rock that forms Earth's outer surface

1. / a system that determines the distance of an object underwater by recording echoes of soundwaves
2. / transfer of heat by movements of a fluid
4. / direct transfer of energy through empty space through electromagnetic waves
