Chapter 5

2. An undersea mountain chain where new ocean floor is produced; a divergent plate boundary under the ocean.
5. The process by which molten material adds new ocean crust to the ocean floor.
6. The hypothesis that the continents slowly move across Earth's surface.
9. The theory that pieces of earth's lithosphere are in constant motion, driven by convection currents in the mantle.
10. The process by which oceanic crust sinks beneath a deep ocean trench and back into the mantel at a convergent plate boundary.
11. The transfer of thermal energy by the movement of a fluid.
14. A plate boundary where two plates move away from each other.
15. A plate boundary where two plates move past each other in opposite directions.

1. A plate boundary where two plates move towards each other.
3. The movement of a fluid, caused by difference in temperature, that transfers heat from one part of a fluid to another.
4. The transfer of energy by electromagnet waves.
7. A Deep valley along the ocean floor beneath which oceanic crust slowly sinks towards the mantel.
8. The molten mixture of rock-forming substances,gas, and water from the mantle.
12. The transfer of thermal energy from one partial of matter to another.
13. An area where magma from deep within the mantel melts tough the crust above it.
