|---|---|---|---|---|---|
| show | the sudden return of elastically deformed rock to its undeformed shape.
🗑
|
||||
| show | the location within the Earth along a fault at which the first motion of an earthquake occurs.
🗑
|
||||
| show | the point on Earth’s surface directly above an earthquake’s starting point, or focus.
🗑
|
||||
| show | energy released in the form of vibrations as rocks along a fault slip into new positions.
🗑
|
||||
| show | a region of numerous, closely spaced faults. (Ex: North Anatolian fault zone in Turkey.)
🗑
|
||||
| Understand how stress builds up along a fault and gets released. | show 🗑
|
||||
| show | With all other factors being equal, the deeper the focus (farther below ground), the lower the intensity, and the shallower the focus (closer to the surface), the greater the intensity.
🗑
|
||||
| show | Earthquakes are most likely to happen along a transform plate boundary. Earthquakes are very common around the Ring of Fire
🗑
|
||||
| Seismograph | show 🗑
|
||||
| show | A tracing of earthquake motion that is recorded by a seismograph.
🗑
|
||||
| show | a measure of the strength of an earthquake.
🗑
|
||||
| Intensity | show 🗑
|
||||
| Understand the difference between the Richter scale and the Moment Magnitude scale for measuring an earthquake’s magnitude. | show 🗑
|
||||
| Understand how the Modified Mercalli scale is used to measure an earthquake’s intensity. | show 🗑
|
||||
| show | a giant ocean wave that forms after a volcanic eruption, submarine (under water) earthquake, or landslide.
🗑
|
||||
| show | an area along a fault where relatively few earthquakes have occurred recently, but where strong earthquakes are known to have occurred in the past.
🗑
|
||||
| show | Earthquakes can cause buildings to sway and topple over, or to collapse. Things like roads and bridges can be torn apart. Buildings constructed in earthquake-prone areas are usually built with features that make them better able to withstand the shaking.
🗑
|
||||
| Understand what people should do before, during and after an earthquake to be safe | show 🗑
|
||||
| Understand how earthquake warnings and forecasts can be developed. | show 🗑
|
||||
| Continental drift | show 🗑
|
||||
| sea-floor spreading | show 🗑
|
||||
| mid-ocean ridge | show 🗑
|
||||
| show | Albert Wegener
🗑
|
||||
| lithosphere | show 🗑
|
||||
| show | the solid plastic layer of the mantle beneath the lithosphere
🗑
|
||||
| divergent boundary | show 🗑
|
||||
| show | the boundary between two plates that are colliding
🗑
|
||||
| transform boundary | show 🗑
|
||||
| subduction zones | show 🗑
|
||||
| show | a zone of active volcanoes surrounded the Pacific Plates
🗑
|
||||
| show | 15; north american plate
🗑
|
||||
| show | earthquakes and volcanoes
🗑
|
||||
| magma | show 🗑
|
||||
| lava | show 🗑
|
||||
| show | the opening of a valcano
🗑
|
||||
| show | a volcanically active area of earths surface, commonly far from a tectonic plate boundary
🗑
|
||||
| show | a crack through which lava flows to earths surface
🗑
|
||||
| show | describes magma or igneous rock that is rich in magnesium and iron that is generally dark in color. comes from melted oceanic crust
🗑
|
||||
| felsic | show 🗑
|
||||
| show | the resistance to flow of a fluid. describes how sticky or runny magma is.
🗑
|
||||
| pyroclastic material | show 🗑
|
||||
| show | a large, circular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink
🗑
|
||||
| show | swarm of small earthquakes, increased gasses or small plumes of ash, ground inflation, changes in the slope of the volcanoes flank
🗑
|
||||
| characteristics of mid ocean ridge | show 🗑
|
||||
| show | fossil plant in Antarctica, mountain matched, similar coastlines
🗑
|
||||
| show | divergent, convergent, and transform

🗑
|
||||
| formation of the hawaiian islands | show 🗑
