Faults
Compression stress is applied to this kind of fault.
Reverse fault.
_____________________ are created when materials in the Earth shift suddenly.
Seismic waves
Shield Volcano
Cinder Cone Volcano
Composite Volcano
Caldera Volcano
Stress is a force that usually triggers an(a)___________.
An earthquake
Type of stress that causes sqeezing.
Compression
The plates that are sliding past one another are known as____________ boundaries.
Transform boundaries.
We get these waves when seismic waves travel in a serpent fashion.
P waves, primary waves, pressure or compressional waves.
Volcanoes are the _________ of earth´s surface.
Geological Arquitects
Where can you find volcanoes?
The ring of fire along plate boundaries.
Fault that has the footwall above the hanging wall.
Normal Fault
One example of this kind of fault is the San Andreas Fault.
Strike Slip Fault
Define earthquake
Earth's crust moving suddenly as a result of seismic waves.
Difference between explosive and non explosive volcanoes.
Nonexplosive eruptions produce mostly lava and have a slow flow, explosive eruptions produce mostly pyroclastic material. Nonexplosive eruptions are the most common type of eruption.
How do volcanoes under the sea form?
By two plates moving apart or pulling apart- Divergent boundaries.
They are _________ types of major seiemic waves.
Three
P - primary waves, pressure or compressional waves.
S- secondary waves, shear waves.
Surface waves divided into: Rayleigh and Love waves.
stretching similar to a running band causes this kind of fault.
Normal Fault
Seismic wave types
They are P waves, S waves, Rayleigh waves and love waves both surface waves.
Define Focus
Focus is related to the place inside earth´s crust where the earthquakes originates or triggers.
What is the formation mechanism of hot spot volcanism?
Middle of tectonic plates can push through the crust and forms a volcano building slowly a line of volcanic islands.
In the twenty-first century, an earthquake struck seven nations.
The 2004 Indian Ocean Tsunami.
Faults can be found at ________________ boundaries.
Plate boundaries.
How are seismic wave amplitude and magnitude measured?
Amplitude by the instrument Seismograph and measure by scales 0-10 or - negative numbers.
Mercalli
Ritcher
Moment magnitude scale
Define fault
Fracture or fractures between two blocks of rock.
Name three hotspot-based islands.
Caribbean islands
Hawaiian islands
Aleutians islands
Iceland islands
Galapagos islands
Easter islands
Stage in which a volcano is not likely to erupt.
Inactive or extinct volcano.
