Continental Drift |
When continents move from place to place slowly. |

Plate Tectonics |
The theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.
|
|
|
Pangaea |
A supercontinent that incorporated almost all the landmasses on Earth.
|
|
|
Lithospheric Plates |
Regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle.
|
|
|
Convection Currents |
The transfer of heat by the mass movement of heated particles into an area of cooler fluid
|
|
|
Transform Boundary |
A type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.
|
|
|
Seafloor Spreading |
A process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
|
|
|
Convergent Boundary |
Also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
|
|
|
Subduction Zones |
Sites of high rates of volcanism, earthquakes, and mountain building.
|
|
|
Divergent boundary |
A linear feature that exists between two tectonic plates that are moving away from each other.
