Geology and Earth Structure Questions
Which type of seismic wave travels through the Earth's liquid outer core?
-
P-waves
-
S-waves
-
Surface waves
-
Love waves
B
Correct answer
Explanation
S-waves, also known as secondary waves, can only travel through solid materials and are slower than P-waves. They are the second to arrive at a seismic station after an earthquake.
What is the term used to describe the point within the Earth where an earthquake originates?
-
Epicenter
-
Hypocenter
-
Magnitude
-
Intensity
B
Correct answer
Explanation
The hypocenter is the point within the Earth where an earthquake originates, while the epicenter is the point on the Earth's surface directly above it.
Which type of seismic wave causes the ground to move in a vertical direction?
-
P-waves
-
S-waves
-
Surface waves
-
Love waves
A
Correct answer
Explanation
P-waves, also known as primary waves, cause the ground to move in a vertical direction and are the fastest seismic waves.
What is the term used to describe the recording of seismic waves?
-
Seismogram
-
Magnitude
-
Intensity
-
Epicenter
A
Correct answer
Explanation
A seismogram is a graphical representation of the seismic waves recorded by a seismograph.
Which type of seismic wave travels along the Earth's surface?
-
P-waves
-
S-waves
-
Surface waves
-
Love waves
C
Correct answer
Explanation
Surface waves travel along the Earth's surface and are the slowest seismic waves.
What is the term used to describe the frequency of seismic waves?
-
Magnitude
-
Intensity
-
Frequency
-
Period
C
Correct answer
Explanation
Frequency refers to the number of oscillations of seismic waves per unit time.
Which type of seismic wave causes the ground to move in a horizontal direction?
-
P-waves
-
S-waves
-
Surface waves
-
Love waves
B
Correct answer
Explanation
S-waves, also known as secondary waves, cause the ground to move in a horizontal direction and are slower than P-waves.
What is the term used to describe the amplitude of seismic waves?
-
Magnitude
-
Intensity
-
Amplitude
-
Period
C
Correct answer
Explanation
Amplitude refers to the maximum displacement of seismic waves from their equilibrium position.
