What does it mean?
Linear Scale
A scale that uses equal divisions to represent equal values
Deflection of a wave due to a change in the material through which it is traveling
Refraction
Name all of the types of faults
Dip-Slip (normal and reverse), strike-slip, and oblique-slip
You are comparing two waves, The first has a longer wavelength than the second. How do the frequencies compare?
The second has a higher frequency. Remember, wavelength and frequency are opposites.
What single plate is responsible for the volcanoes I the Ring of Fire?
The pacific plate
Logarithmic Scale
A scale that uses equal divisions to represent multiplying by a specific number
A mountain formed by the folding of the earth's crust caused by the collision of tectonic plates
Folded mountain
Which types of mountains can be formed by magma? What type can be formed by the convergence of plates that both have continental crust?
Dome and volcanic mountains are formed by magma, while folded mountains are made by the convergence of two plates with continental crust.
Of the two types of seismic body waves, which is longitudinal and which is transverse? Which moves faster? Which cannot travel through liquid inside the earth?
P waves are longitudinal and travel faster, while S waves are transverse and cannot travel through liquid inside the earth.
The tallest volcanoes are which type of volcano?
composite cones
Epicenter
The point on the earth's surface directly above the focus
A mountain formed ty magma pushing up on the lithosphere without breaking through it
Dome Mountain
Where must the epicenter of an earthquake be in order to produce a tsunami? In what depth of the water does the tsunami move quickly? In what depth of the water are the waves large?
It must be in the ocean in deep water. It moves quickly in deep waters but is largest in shallow water.
Tell the three wave types you see on a seismograph in an earthquake, and their order
P waves, S waves, surface waves. P and S waves are body waves (in the earth) and s waves are on the surface, and are the largest.
Which volcanoes are mostly pyroclastic?
cinder cones
Transverse Wave
A wave that vibrates perpendicular to the direction it travels
A mountain formed by a volcano
Volcanic Mountain
A seismograph measures an earthquake of magnitude 3 on the Richter scale, followed by one of magnitude 7, then magnitude 4. Identify the foreshock, aftershock, and main earthquake. Compare the strengths of the main earthquake to the foreshock and the aftershock.
The foreshock is the one that is magnitude 3, the main earthquake is the magnitude 7, and the aftershock is the one with a magnitude of 4. The strengths are compared in multiples of 32...
Waves that do not appear on a seismograph are in a _________ zone.
shadow
which volcanoes are mostly lava?
shield volcanoes
Longitudinal Wave
A wave that vibrates parallel to the direction it travels
Hot pieces of solid rock emitted during many volcanic eruptions
Pyroclastic Material
Explain Elastic Rebound theory in your own words
The blocks of a rock on a fault initially hold onto each other with friction. As they move, they bend, which builds up tension. Eventually, the tension is too great and the blocks move suddenly, which produces a lot of shaking. That's an earthquake.
How can you tell whether a seismograph is closer to the epicenter of an earthquake than another?
The faster the S waves appear after the p waves, the closer the seismograph is to the epicenter
which volcanoes are made from a lot of both pyroclastic material and magma?
composite cones
