Chapter 5 Vocab

3. The transfer of energy by electromagnetic waves
4. A string of volcanoes that form as a result of subduction of one oceanic plate beneath a second oceanic plate.
5. The transfer of thermal energy from one particle of matter to another.
8. The process by which molten material adds new oceanic crust to the ocean floor.
9. The pressured remains or traces of an organism that lived in the past.
11. An undersea mountain chain where new ocean floor is produced; a divergent plate boundary under the ocean.
13. The theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.
14. A section of the lithosphere that slowly moves over the asthenosphere,carrying pieces of continental and oceanic crust.
15. The molten mixture of rock forming substances, gases, and water from the mantle.

1. The process by which oceanic crust sinks beneath a deep ocean trench and back into the mantle at a convergent plate boundary.
2. A deep valley that forms where two plates move apart.
6. A deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle.
7. A weak spot in the crust where magma has come to the surface.
10. The hypothesis that the continents slowly move across Earth’s surface.
12. An area where magma from deep within the mantle melts through the crust above it.
