When molten rock undergoes crystallization above ground, what type of rock results?
Intrusive igneous rock
Extrusive igneous rock
Metamorphic rock
Sedimentary rock
What combination of processes can transform a metamorphic rock to sediments?
Erosion, crystallization, and melting.
Heating, pressure, and lithification.
Melting, crystallization, and compaction.
Exposure, weathering, and erosion.
What sequence of events could lead to magma becoming soil?
Erosion and deposition followed by exposure to heat and pressure.
Compression and lithification followed by erosion and deposition.
Crystallization followed by exposure and weathering.
Crystallization followed by increased heat and pressure.
Which of the following rock types form from placing other rocks under heat and pressure?
Sedimentary rock
Metamorphic rock
Intrusive igneous rock
Extrusive igneous rock
According to the rock cycle, which of the following transitions are possible? Assume an unlimited number of steps.
An intrusive igneous rock becomes a sedimentary rock.
A sedimentary rock becomes soil.
A metamorphic rock becomes an extrusive igneous rock.
All of the above are possible.
What kind of boundary or zone is shown in the image above?
Subduction zone
Divergent boundary
Collision zone
Transform boundary
Which type of plate boundary or zone would be most likely to lead to above-ground volcanic activity?
Subduction zone
Divergent boundary
Collision zone
Transform boundary
Which boundary or zone adds new material to the lithosphere (the hard outer crust of the Earth)?
Subduction zone
Divergent boundary
Collision zone
Transform boundary
In what way does a transform boundary differ from the other boundary types?
Transform boundaries are always found on the ocean floor.
Transform boundaries can result in volcanic activity.
At a transform boundary, one plate slides beneath the other.
At a transform boundary, the plates move in a direction that is parallel to the boundary line.
The highest mountains in the world are the Himalayas, at the border between the Indian and Eurasian plates. The Himalayas formed in a ________________.
subduction zone
divergent boundary
collision zone
transform boundary
In which seismogram is the time probe placed at the beginning of the P-waves?
Seismogram A
Seismogram B
Seismogram C
Seismogram D
Suppose that an earthquake has just occurred, as pictured below. The first P-wave is shown as the larger circle (the purple one) and the first S-wave is shown as the smaller circle (the green one). What would the seismogram in Recording Station A display at the moment the image below was taken?
Which of the following has the two vertical probes in the proper positions to find the correct value for Δt
?
An earthquake has just occurred. Seismic waves from the earthquake are detected at two recording stations. At Recording Station A, Δt=45s
. At Recording Station B, Δt=100s
. Which recording station is farther away from the epicenter?
Station A is farther from the epicenter than station B.
Station B is farther from the epicenter than station A.
Stations A and B are the same distance from the epicenter.
Cannot be determined.
Suppose that Recording Station N is located 200 km north of the epicenter of an earthquake, and Recording Station S is located 100 km south of the epicenter of the same earthquake. Which of the following statements would be true?
At Recording Station S, the S-wave would arrive before the P-wave.
The P-wave would arrive at Recording Station N before it would arrive at Recording Station S.
The value of Δt
at Recording Station N would be greater than Δt
at Recording Station S.
The value of Δt
at Recording Station N would be less than Δt
at Recording Station S.
Which of the three recording stations was closest to the epicenter of the earthquake, based on the seismograms shown above?
Recording station A
Recording station B
Recording station C
Cannot be determined.
Suppose you have seismograph data from two recording stations for an earthquake. You have calculated the distance of the epicenter from each station, which is indicated with the circles shown above. What do you know about where the epicenter of the earthquake was located?
The epicenter was somewhere between locations 1 and 2.
The earthquake had two epicenters, at locations 1 and 2.
The epicenter was either at location 1 or 2.
You cannot tell anything about the location of the epicenter.
Suppose that an earthquake occurs, and the epicenter is 80 km from a recording station with a seismograph. At that recording station, how much time will pass between the arrival of the first P wave and the arrival of the first S wave? (In other words, what will ΔT
be?)
about 8 seconds
about 10 seconds
about 80 seconds
about 640 seconds
Recording station X has determined that the epicenter of a recent earthquake was 250 km away. No information is available yet from any other recording stations. What can you conclude about the location of the epicenter?
The epicenter was located somewhere on a circle centered at Recording station X, with a radius of 125 km.
The epicenter was located somewhere on a circle centered at Recording station X, with a radius of 250 km.
The epicenter was located somewhere on a circle centered at Recording station X, with a radius of 500 km.
You know nothing about the location of the epicenter until there is data from at least three different recording stations.
Two different recording stations have found that they had the same value for ΔT
after an earthquake. If this is all the information they have so far, what can they conclude?
The epicenter is exactly halfway between the two recording stations.
The epicenter is the same direction from both recording stations.
The epicenter is the same distance from both recording stations.
They know nothing about the location of the epicenter until they have data from one more recording station.
