Earthquakes
| Question | Answer |
|---|---|
| earthquakes | a violent shaking that causes major damage |
| crust | the outer layer of the earth |
| fault | a crack in the earths crust |
| mantle | apart of the earth between the core and the crust |
| lithospheric | the rigid outer part of the earth |
| lithospheric plates | regions of earth crust and upper mantle that are fractured into plates |
| seismologists | scientific study of earthquakes and propagation of elastic waves through the earth or other planet |
| convergent | when one or both of the tectonic plates is composed of oceanic crust |
| divergent | is a linear feature that exists between two tectonic plates that are moving away from each other. |
| transform | is a type of fault whose relative motion is predominantly horizontal |
| subduction | a sideways and downward movement of the edge of a plate in the earth's crust and into the mantle beneath another plate. |
| convection | movement of the heated parts of a liquid or gas. |
| s wave | a transverse earthquake energy wave that travels through the interior of the earth |
| p wave | a longitudinal earthquake energy wave that travels through the interior of the earth |
| surface wave | A seismic wave that travels across the surface of the Earth |
| focus | a point at which rays of light, heat, or other radiation meet |
| epicenter | The point on the earth's surface vertically above the focus of an earthquake |
| Mercalli scale | The Mercalli scale is a seismic scale used for measuring the power and intensity of an earthquake. |
| ricter scale | The ricter scale records the size of the earthquake on the basis of a seismograph |
| moment magnitude scale | The moment magnitude scale measure the size of a earthquake by the energy that is released |
| magnitude | The size or extent of something |
| tsunami | A tsunami is a high sea wave that is caused by the effect of the earthquake |
| liquefaction | any process that can generate any way like this liquid can turn into a solid or gas |
| aftershock | A aftershock is when a place that had a large earth has another smaller earthquake in the same area |
| seismology | a branch in science that deals with earthquake and other related facts |
| seismograph | A seismograph is an instrument that measures and records detail from when an earthquake strikes |
| compression | The less increase in volume and a higher increase in pressure |
| tension | when the ground stretches in the middle |
| plateau | an area that has high grounds |
| shearing | |
| normal fault | |
| reverse fault |
