P Waves Questions and Answers
- 1.
Which type of seismic wave is the fastest?
- A.
P wave
- B.
S wave
- C.
Surface wave
- D.
Love wave
Correct Answer
A. P waveExplanation
P waves are the fastest seismic waves and can travel through solids, liquids, and gases. They are compressional waves that vibrate parallel to the direction of wave propagation.Rate this question:
-
- 2.
What is the primary characteristic of P waves?
- A.
They can only travel through solids.
- B.
They cause the most damage during an earthquake.
- C.
They are transverse waves.
- D.
They compress and expand the ground in the direction of wave propagation.
Correct Answer
D. They compress and expand the ground in the direction of wave propagation.Explanation
P waves are compressional waves that cause the ground to compress and expand in the direction of wave travel. This alternating compression and expansion creates a pushing and pulling effect, allowing P waves to propagate through different mediums.Rate this question:

- 3.
Which of the following is NOT a type of body wave? (Select all that are applicable)
- A.
P wave
- B.
S wave
- C.
Rayleigh wave
- D.
Love wave
Correct Answer(s)
C. Rayleigh wave
D. Love waveExplanation
Rayleigh waves and Love waves are types of surface waves, while P waves and S waves are body waves. Body waves travel through the Earth's interior, while surface waves propagate along the Earth's surface.Rate this question:
-
- 4.
What is the travel path of P waves in the Earth?
- A.
Straight lines along the Earth's surface
- B.
Curved paths within the Earth's interior
- C.
Sine wave patterns
- D.
Zigzag paths resulting from reflection
Correct Answer
B. Curved paths within the Earth's interiorExplanation
P waves travel along curved paths within the Earth's interior. When P waves encounter boundaries between different materials, they can refract, reflect, or diffract. These interactions cause the path of propagation to curve.Rate this question:
-
- 5.
When a P wave encounters a boundary and reflects back, what is this phenomenon called?
- A.
Refraction
- B.
Diffraction
- C.
Reflection
- D.
Interference
Correct Answer
C. ReflectionExplanation
When a P wave encounters a boundary and bounces back, it undergoes reflection. Reflection of seismic waves can provide valuable information about subsurface structures and help in geological exploration.Rate this question:
-
- 6.
Which statement about the characteristics of P waves is incorrect?
- A.
They travel faster than S waves.
- B.
They can pass through liquids.
- C.
They have a higher frequency than Love waves.
- D.
Their motion is perpendicular to the wave direction.
Correct Answer
D. Their motion is perpendicular to the wave direction.Explanation
The motion of P waves is parallel to the wave direction, not perpendicular. This makes them compressional waves, where particles move back and forth along the same direction as the wave propagation.Rate this question:
-
- 7.
Which of the following waves causes the most intense shaking during an earthquake?
- A.
P wave
- B.
S wave
- C.
Rayleigh wave
- D.
Love wave
Correct Answer
C. Rayleigh waveExplanation
The Rayleigh waves, also called ground rolls, cause the most intense shaking during an earthquake. They travel like ocean waves over the surface of the Earth, moving the ground surface up and down. This is the type of wave motion that causes so much structural damage.Rate this question:
-
- 8.
What happens to the speed of P waves as they travel through denser materials?
- A.
The speed decreases
- B.
The speed increases
- C.
The speed remains constant
- D.
The speed becomes zero
Correct Answer
B. The speed increasesExplanation
The speed of P waves increases as they travel through denser materials. P waves, or primary waves, are compressional waves that can travel through solids, liquids, and gases. In denser materials, such as the Earth's interior, the particles are closer together, leading to a higher elastic modulus and, consequently, an increase in the speed of P waves.Rate this question:
-
- 9.
Which type of seismic wave causes the most damage to buildings?
- A.
P wave
- B.
S wave
- C.
Rayleigh wave
- D.
Love wave
Correct Answer
B. S waveExplanation
Love waves are considered to cause more damage than the other waves waves. Love waves are particularly damaging to structures because their side-to-side motion can generate strong shearing forces in the ground, leading to significant structural damage.Rate this question:
-
- 10.
What is the major factor influencing the reflection of P waves at a boundary?
- A.
Wavelength of the wave
- B.
Speed of the wave
- C.
Amplitude of the wave
- D.
Density contrast between the two materials
Correct Answer
D. Density contrast between the two materialsExplanation
The density contrast between the two materials is the major factor influencing the reflection of P waves at a boundary. When P waves encounter a boundary between different materials with contrasting densities, a portion of the wave gets reflected back while the rest continues to propagate into the new medium.Rate this question:
