|
| Large flat areas on the sea floor. They form from mud and debris settling on the sea floor. |
|
| Continental Collision Zone |
|
| Marks the final disappearance of an ocean basin between converging continents. Results in crumpling and mountain ranges. |
|
|
|
| When the supercontinents become the modern regular continents and, well, drift. (Alfred Wegener) |
|
|
|
| A region where the sea floor flattens and continental crust meets oceanic crust.
|
|
|
|
| The flooded part of a continent. |
|
|
|
| An assemblage of cratons and orogens. |
|
|
|
| The drop-off at the seaward edge of the continental shelf |
|
|
|
| Fractures in the lithosphere where two plates move apart. |
|
|
|
| A stable core of very ancient rock (continental crust). |
|
|
|
| Where two plates move towards each other. |
|
|
|
|
|
|
| Difference of gravity between different points on Earth. |
|
|
|
| The property whereby the lithosphere maintains a floatational balance as it ride the asthenosphere like a surfboard.
|
|
|
|
| The magnetic field generated by the outer core, surrounding the Earth. Caused by electrical energy from friction in the inner core. |
|
|
|
| When the north and south poles reverse. See also: Polar Wandering. |
|
|
|
| The place where the ocean-capped lithosphere sings into the asthenosphere. |
|
|
|
| A type of continental crust which are elongate and have been bent and fractured in continental collisions.
|
|
|
|
| The magnetism locked in ancient minerals. |
|
|
|
| The study of the movement of the lithosphereic plates. |
|
|
|
| The branch of tectonics that deals with the /interactions/ of the lithospheric plates. |
|
|
|
| The north-south directionality of the Earth’s magnetic field.
|
|
|
|
| The poles don’t wander, the continents wander, making it seem like they do. |
|
|
|
| The result of the cycle of spreading. Also a popular MMORPG. |
|
|
|
| The result of ocean crusts moving and being pushed apart by lava.
As it grows, it has alternating magnetic bands. |
|
|
|
| Another term for divergent plate margins. |
|
|
|
| Fractures in the lithosphere where two plates slide past each other. |
|
|
|
| The horizontal or sliding motion of transform plate margins. |
|
|
|
| When slabs of lithosphere (capped by oceanic crust) sinks into the mantle. |
|
|
|
|
|
|
| Where subduction happens. |
|
|
|
| Large continental complexes. |
