| Anticline | Ant Hill |
| Syncline | Sink Line |
| The oldest rock in a anticline is at the? | center |
| The oldest rock in a syncline is at the? | exteriour |
| EARTHQUAKES | EARTHQUAKES |
| Hypocenter | Foucus of an earthquake. |
| Soundwaves travle faster | throught the ground. |
| TYPES OF FAULTS | TYPES OF FAULTS |
| Normal fauls form during extension so.. | the hanging wall moves down. (where the miner hangs his lantern) |
| Reverse faults form during compression so... | the hanging wall moves up steeply. |
| Thrust faults form during compression so | the hanging wall moves at a gentle slope. |
| Strike slip fault | when one section of land slide past the other.Like a base joint on a chop saw. |
| TYPES OF EARTHQUAKE MOTION | TYPES OF EARTHQUAKE MOTION |
| Compressional | (P-Wave) Like a slinky toy. |
| Shear | (S-Wave) Like cracking a whip. |
| Surface waves | Like the waves of the sea. |
| INTERLUDE D | INTERLUDE D |
| Outer core | liquid iron |
| Inner core | solid iron |

| CRUSTAL DEFORMATOIN | CRUSTAL DEFORMATION |
| Undeformed | cracked, but not bent of faulted |
| Deformed | broken or folded |
| STRAIN | STRAIN |
| Shear Strain | Like pushing on the top of a deck of cards and moving |
| Tension | Streching of the crust |
| Strike slip | horosontal shear stress |
| Hydrodynamic | Compression in all directions |
| Monoclines | the funky bend in the earth that has a "V" and a plunging line |
| Dome: Oldest rocks in the? | center |
| Basin: Yongest rocks in the? | Center!!!!!!!!!!!!!!! |

| REMEMBER: | plutons and dikes are younger than the layers. |
| UNCONFORMITIES | UNCONFORMITIES |
| Angular Unconformity | two rock beds collide at angles |
| NON Conformity | Horizontialish conformity between two rock beds |
