Definition
| The shaking and trembling that results from the movement of rock beneath Earth's surface. |
|
|
Term
|
Definition
| A force that acts on rock to change its shape or volume. |
|
|
Term
|
Definition
| The amount of space an object takes up. |
|
|
Term
| What do shearing,tension,and compression work over millions of years to do?? |
|
Definition
| To change the shape and volume of rock. |
|
|
Term
| Describe shearing and tell what effect it has on rock. |
|
Definition
| It is a stress force that pushes a mass of rock in two opposite directions. Its effect is that it can cause rock to break and slip apart or to change its shape. |
|
|
Term
| What kind of fault is shearing?? |
|
Definition
|
|
Term
| Describe tension and tell what effect it can have on rock. |
|
Definition
| Tension is another stress force that pulls on the crust,stretchhing rock so that it becomes thinner in the middle. The effect of this is somewhat like pulling apart warm bubblegum. |
|
|
Term
| Describe compression and tell what affect it has on rock. |
|
Definition
| Compression is another stress force that squeezes rock until it folds or breaks. The affect is that one plate pusing against another can compress rock. |
|
|
Term
| What kind of fault is tension?? Compression?? |
|
Definition
| Normal fault is tension and reverse is compression |
|
|
Term
|
Definition
| Any change im the volume or shape of Earth's crust. |
|
|
Term
| How does deformation change earth's surface?? |
|
Definition
| Deformation changes Earth's surface because the plates slowly move and crack the crust and also be bent, stretched, tilted, folded, and slid. |
|

Definition
|
|
Term
| Where to faults usually occur?? |
|
Definition
| Along plate boundaries, where the forces of plate motion compress, pull, or shear the crust so much that the crust breaks. |
|
|
Term
| What happens at a strike-slip fault?? |
|
Definition
| The rocks on either side of the fault slip past each other sideways with little up or down motion. |
|
|
Term
| What fault in California is an example of a strike-slip fault?? |
|
Definition
|
|
Term
| What happens at a normal fault?? |
|
Definition
| The fault is at an angle, so one block lies below the fault while the other lies below the fault. |
|
|
Term
|
Definition
| The half or the fault that lies above the fault. |
|
|
Term
|
Definition
| The half of the fault that lies below the fault |
|
|
Term
| What rift valley is an example of a normal fault?? |
|
Definition
| The Rio Grande rift valley. |
|
|
Term
| What happens at a reverse fault?? |
|
Definition
| The same thing as a normal fault but they move in opposite directions. |
|
|
Term
| What mountains did a reverse fault create a part of?? |
|
Definition
| The Appalachian Mountains |
|
|
Term
|
Definition
| The force that opposes the motion of one surface as it moves across another surface. |
|
|
Term
| Over millions of years, fault movement can change what?? |
|
Definition
| A flat plain into a towering mountain range. |
|
|
Term
| When normal faults uplift a block of rock, what forms?? |
|
Definition
|
|
Term
|
Definition
| bends in rock that form when compression shortens and thickens part of Earth's crust. |
|
|
Term
|
Definition
| A fold in rock that bends upward into an arch. |
|
|
Term
|
Definition
| A fold in rock that bemds downward into an arch. |
|
|
Term
|
Definition
| A large area of flat land elevated high above sea level. |
