| Question | Answer |
| the opposite of uplift is___________ | subsidence |
| the balance between the crust and the mantle below it is | isastasy |
| Explain the difference between the two types of strain | Elastic strain does not permanently change, or deform, rocks. Plastic strain creates a permanent change in shape |
| Describe what happens to the elevation of the land surface when crust thickens | the crust thickness it rises the elevation rising |
| Name one result of rock failure | faults |
| which type of deformation Is produced by compression of plastic crust | folds |
| list copy graphic organizer down below , and use it to show three types of stress | Compression, tension, and shear |
| identify the type of stress that deformed the rocks shown below. What kind of strain resulted from the stress | Compression stress cause folds. This is plastic strain. The rock will not return to its original shape |
| predict what would happen to the height of the land surface of Antarctica if the ice sheet started to melt | As the weight of ice is removed from the crust, the land surface will move upward until balance (isostasy) is restored |
| reflect on the relation ship between vertical and horizontal motion how are they related? when are they not related | Horizontal motion creates uplift or making faults. They are examples of vertical motion. The vertical motion caused by eroding a mountain or by melting an ice sheet does not require horizontal motion |
