| Question | Answer |
|---|---|
| slow to rapid sinking or settling of Earth materials | subsidence |
| smaller earthquakes after the major event | aftershock |
| energy released | magnitude |
| deformation resulting from stress | strain |
| occurs between two plates | interplate earthquake |
| sides displaced horizontally | strike-slip fault |
| surface rupture with vertical component | fault scarp |
| gradual displacement that is not accompanied by a felt earthquake | tectonic creep |
| transformation of a water saturated granular material to a liquid | liquification |
| fracture along which rocks have been displaced | fault |
| instrument that records earthquake displacement | seismograph |
| where an earthquake starts on the Earth's surface | epicenter |
| type of wave that causes the most damage | surface waves |
| point at depth where rocks are ruptured | focus |
| ground shaking caused by the sudden release of energy stored in subsurface rock units | earthquake |
| results because of intensity of shaking increases in direction of fault rupture | directivity |
| occurs within a single plate | intraplate earthquake |
| 12 divisions of intensity concerning levels of shaking, depends on people's perceptions | Mercalli Scale |
| arch shaped folds at ridges | anticline |
| displacement vertically, wall moves relative to the foot | dip-slip fault |
| shear waves that only travel through solids | secondary waves |
| bowl shaped folds at basin | syncline |
| fast waves which travel through solid, liquid, or gas | primary waves |
| small earthquakes before major event | foreshakes |
| removal of subterranean earth by natural processes | sinkholes |
| 4 miles thick, less than 200 million years old | oceanic crust |
| waves changing direction | refracted |
| mostly solid layer that surrounds the outer core | mantle |
| edges of plates slide past one another | transform boundaries |
| hot, slow moving layer of weak rock under the lithosphere | asthenosphere |
| developed theory of continental drift | Alfred Wegener |
| solid inner layer of the earth | core |
| theory of Earth as a magnetic field | paleomagnetism |
| new lithosphere is being produced and neighboring parts of plates are moving away from each other | diverging plates |
| 22 to 44 miles thick, several billion years old | continental crust |
| plates colliding | converging plates |
| developed theory of sea floor spreading | Hess & Deitz |
| processes associated with creation, movement and destruction of lithospheric plates | plate tectonics |
| study of earthquakes and the passage of seismic waves through earth | seismology |
| boundary of the mantle and the crust | Moho |
