Geology and Earth Structure Questions
Which layer of the Earth is responsible for the Earth's tides?
-
Crust
-
Mantle
-
Outer Core
-
Oceans
D
Correct answer
Explanation
The Earth's tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans.
Which layer of the Earth is responsible for the Earth's rotation?
-
Crust
-
Mantle
-
Outer Core
-
Inner Core
D
Correct answer
Explanation
The Earth's rotation is caused by the Earth's inner core.
Which layer of the Earth is responsible for the Earth's gravity?
-
Crust
-
Mantle
-
Outer Core
-
Inner Core
D
Correct answer
Explanation
The Earth's gravity is caused by the Earth's inner core.
What is the name of the point on the Earth's surface directly above the focus of an earthquake?
-
Epicenter
-
Hypocenter
-
Magnitude
-
Intensity
A
Correct answer
Explanation
The epicenter is the point on the Earth's surface directly above the hypocenter, which is the point where the earthquake starts.
The Richter scale measures the:
-
Magnitude of an earthquake
-
Intensity of an earthquake
-
Depth of an earthquake
-
Duration of an earthquake
A
Correct answer
Explanation
The Richter scale measures the magnitude of an earthquake, which is a measure of the energy released during the earthquake.
Which of these is NOT a type of seismic wave?
-
P-waves
-
S-waves
-
L-waves
-
T-waves
D
Correct answer
Explanation
T-waves are not a type of seismic wave. P-waves are primary waves, S-waves are secondary waves, and L-waves are surface waves.
What is the name of the process by which magma rises to the Earth's surface?
-
Eruption
-
Intrusion
-
Subduction
-
Divergence
A
Correct answer
Explanation
Eruption is the process by which magma rises to the Earth's surface. Intrusion is the process by which magma cools and solidifies beneath the Earth's surface.
Which of these is NOT a type of earthquake fault?
-
Strike-slip fault
-
Dip-slip fault
-
Reverse fault
-
Normal fault
C
Correct answer
Explanation
Reverse faults are not a type of earthquake fault. Strike-slip faults, dip-slip faults, and normal faults are all types of earthquake faults.
What is the name of the process by which two tectonic plates move away from each other?
-
Convergence
-
Divergence
-
Subduction
-
Transform boundary
B
Correct answer
Explanation
Divergence is the process by which two tectonic plates move away from each other.
What is the name of the process by which one tectonic plate moves beneath another?
-
Convergence
-
Divergence
-
Subduction
-
Transform boundary
C
Correct answer
Explanation
Subduction is the process by which one tectonic plate moves beneath another.
What is the name of the process by which two tectonic plates move past each other?
-
Convergence
-
Divergence
-
Subduction
-
Transform boundary
D
Correct answer
Explanation
Transform boundaries are the boundaries between tectonic plates where the plates move past each other.
Which of these is NOT a type of earthquake wave?
-
P-waves
-
S-waves
-
L-waves
-
R-waves
D
Correct answer
Explanation
R-waves are not a type of earthquake wave. P-waves, S-waves, and L-waves are all types of earthquake waves.
What is the name of the theory that explains how the Earth's continents have moved over time?
-
Plate tectonics
-
Continental drift
-
Seafloor spreading
-
Subduction
A
Correct answer
Explanation
Plate tectonics is the theory that explains how the Earth's continents have moved over time.
What is the name of the process by which new oceanic crust is formed?

Seafloor spreading
-
Subduction
-
Continental drift
-
Plate tectonics
A
Correct answer
Explanation
Seafloor spreading is the process by which new oceanic crust is formed.
What is the name of the process by which oceanic crust is recycled back into the mantle?
-
Subduction
-
Seafloor spreading
-
Continental drift
-
Plate tectonics
A
Correct answer
Explanation
Subduction is the process by which oceanic crust is recycled back into the mantle.
