Eq&Volc IRE 5-6
Earthquakes and Volcanoes Ch 5&6 IRE Barnetts
| Question | Answer |
|---|---|
| seismology | the study of earthquakes |
| seismo | earthquake, vibration |
| Deformation | the bending, tilting and breaking of the Earth's crust; the change in the shape of rock in response to stress |
| de | do the opposite of |
| elastic rebound | the sudden return of elastically deformed rock to its undeformed shape |
| seismic wave | a wave of energy that travels through the Earth and away from an Earthquake in all directions |
| P waves | a seismic wave that causes particles of rock to move in a back and forth direction |
| S Waves | a seismic wave that causes particles of rock to move in a side-to-side direction |
| Seismograph | an instrument that records vibrations in the ground and determines the location and strength of an earthquake |
| Seismogram | a tracing of earthquake motion that is created by a seismograph |
| epicenter | the point on Earth's surface directly above an Earthquake's starting point, or focus |
| Epi | upon, attached to, over |
| focus | the point along a fault at which the first motion of an earthquake occurs |
| gap hypothesis | a hypothesis that is baded on the idea that a major earthquake is more likely to occur along part of an active fault where no earthquakes have occured for a certain period of time |
| seismic gap | an area along a fault where relatively few earthquakes have occurred recently |
| volcano | a vent or fissure in the Earth's surface through which magma and gases are expelled |
| magma chamber | the body of molten rock that feeds a volcano |
| vent | an opening at the surface of the Earth through which volcanic material passes |
| crater | a funnel-shaped pit near the top of the central vent of a volcano |
| caldera | a large, semicircular, depression that forms when the magma chamber below a volcano partially empties and causes the ground above it to sink |
| lava plateau | a wide, flat landform that results from repeated nonexplosive eruptions of lava that spread over a large area |
| rift zone | an area of deep cracks that forms between two tectonic plates that are pulling away from each other |
| hot spot | a volcanically active area of Earth's surface far from a tectonic plate boundary |
