Plate Tectonics vocabulary
Vibrations that travel through Earth carrying the energy released during an earthquake.
The force exerted on a surface divided by the area over which the force is exerted.
The crust is a layer of solid rock that includes both dry land and the ocean floor.
Oceanic crust consists mostly of rocks such as basalt. Basalt is dark rock with a fine texture.
Continental crust, the crust that forms the continents, consists mainly of rocks such as granite. Granite is a rock that usually is a light color and has a coarse texture.
The layer of hot, solid material between Earths crust and core.
A rigid layer made up of the uppermost part of the mantle and the crust.
The soft layer of the mantle on which the lithosphere floats.
A layer of molten iron and nickel that surrounds the inner core of Earth.
A dense sphere of solid iron and nickel at the center of Earth.
The transfer of energy through space.
The transfer of heat within a material or between materials that are touching.
The transfer of heat by movement of a fluid.
The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another.
The amount of mass in a given space; mass per unit volume.
The hypothesis that the continents slowly move across Earth’s surface.
The name of the single landmass that broke apart 200 million years ago and gave rise to today’s continents.
A trace of an ancient organism that has been preserved in rock.
An undersea mountain chain where new ocean floor is produced; a divergent plate boundary.
A device that determines the distance of an object under water by recording echoes of sound waves.
The process by which molten material adds new oceanic crust to the ocean floor.
A deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle.
The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust.
A well-tested concept that explains a wide range of observations.
The theory that pieces of Earth_tm)s lithosphere are in constant motion, driven by convection currents in the mantle.
A break in Earth’s crust where masses of rock slip past each other.
A plate boundary where two plates move away from each other.
A deep valley that forms where two plates move apart.
A plate boundary where two plates move toward each other.
A plate boundary where two plates move past each other in opposite directions.
