1049211595FoldedRock layers are bent or curved
1049211596FaultedRock layers are offset or displaced along a crack
1049211597UpliftedReason why we find fossils hundreds to thousands of meters above sea level
1049211598EarthquakeNatural rapid shaking of the lithosphere
1049211599Seismic wavesWaves that come out from an earthquake
1049211600EpicenterLocation on land or water surface directly above Earthquake focus
1049211601P wavesEarthquake waves that vibrate in the direction the wave is moving
1049211602S wavesEarthquake waves that vibrate at right angles to the direction the wave is moving
1049211603TsunamiLarge wavelength ocean wave that is produced by an Earthquake or landslide
1049211604VolcanoMountain composed of extrusive igneous rocks
1049211605Volcanic eruptionGiving off of gases, lava, and lava rock onto Earth's surface
1049211606MohoSeperation between the mantle and the crust
1049211607LithosphereCrust and the upper portion of the mantle
1049211608AsthenospherePlastic-like portion of the mantle
1049211609Plate tectonicsConcept that Earth's lithosphere is broken up into plates
1049211610Divergent plate boundaryWhere two plates separate and magma rises to fill the separation, usually at mid-ocean ridges
1049211611Convergent plate boundaryWhere two plates collide
1049211612SubductionWhere oceanic crust below continental crust because of its higher density
1049211613Transform plate boundaryWhere two plates slide past one another
1049211614Hot spotVolcanic activity in the middle of plates, how the Hawaiian Islands were formed
