| Question | Answer |
|---|---|
| Continental Rise | Gradual Incline where the steep continental slope merges. |
| Guyots | Flat Topped Sea Mounts |
| Seismic Sea Wave | Same as Tsunami. Big Wave |
| Liquefaction | Where soil can be turned into mobile fluid |
| Sea Mounts | Oceanic Volcanoes |
| Contiental Slop | A steep structure that marks the boundary between continental crust and oceanic crust |
| Surface Wave | Waves that travel at the surface of the earth |
| Earth Quake | The vibration of Earth produced by rapid release of energy |
| Elastic Rebound | The rock springing back. This is what causes the shaking |
| Intensity | A measure of the degree of Earth Quake shaking at a given locale based on the amount of damage. |
| Magnitude | Relies on calcuations that use data provided by seismic records to estimate the amount of energy released @ the source of the Earth Quake |
| Wadati Benioff Zones | Zones in which Earth Quakes occur |
| Rift Vaelly | Deep Down Faulted Structures |
| Oceanic Plateaus | These resemble the flood basalt provinces found on the contients |
| Abyssal Plains | Deep incredibly flat features |
| Convection | The transfer of heat by the mass movement in a substance |
| Conduction | The transfer of heat through matter |
| Geothermal Gradient | Temperature gradually increases with an increase in depth at the rate |
| D " Layer | Waves experience sharp decrease in P-waves here |
| P-Wave-Shadow-Zone | Weak P-Waves enter this zone go undetected |
| Moho | Is a boundary that separates crustal materials from rocks of different composition |
| Asthenosphere | Plascity |
| Lithosphere | Outermost Layer of the Earth |
| Primary (P) Waves | A body wave. Can travel through objects |
| Foreshock | Warning about future earth quakes. Can be days or YEARS before hand |
| Seismogram | The information recorded from seismographs |
| Inertia | Objects at rest tend to stay in rest |
| Seismograph | Its an instrument that measures waves |
| Accertionary Wedge | A chaotic accumulation of deformed sediment and scraps of oceanic crust |
| Active Continental Margins | Located in the pacific oceans |
| Deep Ocean Trenches | Are long relatively narrow creases in the sea floor that form the deepest parts of the ocean |
| Moment Magnitude | Describes large Earth Quakes. Right when it slips and releases the energy |
| Body Wave | They travel through the Earth |
| Continental Margins | Passive and active margins. Movement of the ocean floor |
| Passive Continental Margins | Include the contiental shelf, contiental slope, and the contiental rise |
| Continental Shelf | Is a gently sloping submerged surface extending from the shoreline toward the deep ocean basin |
| Deep Ocean Basin | Tons of Flat areas. Between the continental margin and oceanic ridge |
| Secondary (S) Waves | Body wave. Shake the particles. |
| Echo Sounders | First Devices that used sound to measure water depth |
| Seismic Reflection Profile | Strong low, frequency sounds are produced by explosions or air guns |
| Hypocenter | Another name for the focus |
| Bathymetry | The measurement of ocean depths and the charting of the shape or topography of the ocean floor |
| Richter Scale | Is based on the amplitude of the largest seismic wave recorded on the seismogram |
| Modified Mercalli Intensity Scale | Uses CA's buildings as its standard. Measures strength |
| Aftershock | The last tremors after an Earth Quake |
| Core | the center of the Earth |
| Mantle | Solid Rocky Shell |
| Crust | Thick outerskin of the Earth |
| Discontinuity | The boundary between the two materials |
| Seismic Gaps | Quiet Zones. Most likely to have big earthquakes later |
| Tsunami | Big waves that can go undetected |
| Epicenter | Is the location on the surface right above the focuas |
| Long (L) Waves | Surface Waves. Long Periods |
| Fault Creep | Slow gradual movement. Produces small earthquakes |
| Fault | Large fracture in the Earth's Crust |
| Focus | The sources of the Earth Quake |
| Seismology | The study of Earth Quake Waves |
| Deep Sea Fan | Deposited sediment come down in muddy currents |
