Ch. 19 Earthquake
| Question | Answer |
|---|---|
| This wave arrives first at the seismic station | P wave |
| This is the fastest of all seismic waves | P wave |
| This waves move back and forth and compresses the particles in the ground | P wave |
| This wave is refracted and reflected by the inner core | P wave |
| This wave forms a shadow zone 11,000KM-16,000KM from a seismic station | P wave |
| This wave does not travel through liquids and does not enter the outer core | S wave |
| This wave has the highest amplitude and is the most destructive | Surface wave |
| This wave does not travel through Earth's interior | Surface wave |
| This fault results from vertical movement and tension. (tress would be farther apart) | Normal fault |
| This fault results from vertical movement and compression. (tress would be closer together) | Reverse fault |
| This fault only has horizontal movement and shearing. | Strike-Slip fault |
| What type of fault is the San Andreas fault? | Strik-Slip |
| This fault would be found near a convergent boundary. | Reverse fault |
| When does an earthquake occur? | stress overcomes the strength of the rocks involved |
| Most rocks that exist in Earth’s crust are brittle but become ductile at great depths where temperatures are cooler. | False |
| This is the point of failure where the waves originate. | Focus |
| Where is the epicenter of the earthquake found? | Directly above the focus. |
| Where will the worst damage occur during an earthquake? | At the epicenter |
| Deaths associated with earthquake deaths in sloping areas can result from ____. | landslides |
| A city is located over an active fault, but has not experienced an earthquake for a long period of time. The city is most likely located where? | Over a seismic gap |
| The deformation of materials in response to stress is called | strain |
| This is where movement occurs as a result from a fracture(s). | fault |
| The amount of energy released during an earthquake is measured by its | magnitude |
| This scale measures the size of the largest seismic wave | Richter scale |
| This scale takes into account the size of the fault rupture, the amount of movement along a fault, and the rocks stiffness. | moment magnitude scale |
| This scale rates the damage and other effects of an earthquake. | modified Mercalli scale |
| To locate an epicenter of an earthquake you must have data from how many seismic stations? | Three |
| Seismic belts follow _____________ _________ __________ | tectonic plate boundaries |
| This structural failure occurs when the walls ground floor fail and cause the upper floors, which originally remain intact, to fall and collapse as they hit the ground or lower floors. | pancaking |
| This occurs when seismic waves cause fluid-saturated soil to act like quicksand. | soil liquefaction |
| Fault scarps can produce ___________ offset where the fault intersects the ground surface | vertical |
| The probability of an earthquake occurring is based on the history of earthquakes in an area and | the rate at which strain builds up in a rock |
| These are sections of active faults that haven't experienced an earthquake in a long time. | Seismic gap |
