Question | Answer |
Fault | surface along which rocks move when they pass there elastic limit |
Earthquake | The vibrations produced by the breaking of the rock |
Normal fault | Rock above the fault moves downward in relation to rock below the surface |
Reverse fault | surface is forced up and over the rock below the surface |
Strike Slip Fault | Rocks on either side of the fault are moving past eachother without much upward/downward movement |
Plate | AS large section of warthcrust and rigid upper mantle that moves around on the asthenosphere. |
Siesmic waves | Caused by earthquake and travels through earth |
Focus | The point where energy is released in the earthquake |
Primary wave | Cause particles in rocks to move back and forth is the same directions |
Secondary Wave | more through earth by causing particles in rocks to move at right angles to direction of wave travel |
Surface waves | Move rock particles a backward , rolling motion, and swaying motion |
Epicenter | is the point on earths surface directly above the earthquakes focus |
Wave | Rythmic pattern that carries energy through matter and space |
Crest | The highest point of a wave |
Magnitude | Measure of the energy is released in an earthquake |
Liquefaction | Earthquake can be move like liquid |
Tsunami | Large wave caused my eathquakes |
Seismograph | measures seismic waves from an eathquake |
