Definition
| a place along plate boundaries where many faults are located. |
|
|
Term
|
Definition
| a type of fault where forces of tension are pulling rocks a part. |
|
|
Term
|
Definition
| the fastest moving type of seismic wave, which expands and compresses rock, like the movement of a slinky. Also known as pressure waves can travel through both liquid and solid. |
|
|
Term
|
Definition
| a type of fault where compression pushes rock together also known as a thrust fault. |
|
|
Term
|
Definition
| a measure of the magnitude of an earthquake based on the readings of a seismograph. |
|
|
Term
|
Definition
| the second fastest moving wave, which moves side to side. |
|
|
Term

Definition
| A vibration that travels through Earth carrying the energy released during an earthquake. |
|
|
Term
|
Definition
| an instrument that records seismic waves |
|
|
Term
|
Definition
| a type of stress that pushes 2 adjacent areas of rock in opposite directions. |
|
|
Term
|
Definition
| a force of that causes rock to change shape |
|
|
Term
|
Definition
| a type of fault where rocks slide horizontally past each other in opposite directions, with little up or down motion. |
|
|
Term
|
Definition
| seismic waves that move along Earths surface. They have an up and down motion or a horizontal motion. |
|
|
Term
|
Definition
| a type of stress that stretches rock and makes it thinner. |
|
|
Term
|
Definition
| a giant, fast moving wave that is caused by an undersea earthquake. Also Known as a seismic sea wave. |
|
|
Term
|
Definition
| the soft, flexible upper layer of the mantle, on which the tectonic plate moves. |
|
|
Term
|
Definition
| the theory that all of Earth's continents were once joined together into a single large landmass, and then moved apart, forming the continents we see today |
|
|
Term
|
Definition
| movement within hot fluids, when the heat source is on the bottom, such as in a boiling pot of soup on the stove. Convection currents happen because the hotter material is less dense and rises; when it reaches the surface, it cools and becomes less dense, so it sinks. This rising and sinking creates a circular motion within the fluid. |
