Review the solved problems below to understand question phrasing, answer choices, and step-by-step solution logic prior to starting the full interactive practice drill:

Sample Question 1
Geophysics & Seismological Surveys EASY • MULTIPLE_CHOICE
Which seismic wave is a longitudinal compressional body wave that travels fastest through solids and liquids?
A Love wave
B S-wave (Secondary wave)
C P-wave (Primary wave)
D Rayleigh wave
✓ Correct Answer: C - P-wave (Primary wave)
📖 Step-by-Step Solution & Conceptual Rationale:
P-waves compress and dilate rock in the direction of propagation at highest velocity.
Sample Question 2
Geophysics & Seismological Surveys MEDIUM • MULTIPLE_CHOICE
S-waves (Shear waves) cannot propagate through which Earth layer, proving it is liquid?
A Lower Mantle
B Crust
C Outer Core
D Inner Core
✓ Correct Answer: C - Outer Core
📖 Step-by-Step Solution & Conceptual Rationale:
Liquids lack shear rigidity (shear modulus = 0), completely stopping S-wave transmission.
Sample Question 3
Geophysics & Seismological Surveys EASY • MULTIPLE_CHOICE
The point on the Earth's surface directly vertically above the earthquake hypocenter (focus) is the:
A Anticline
B Epicenter
C Scarp
D Fault trace
✓ Correct Answer: B - Epicenter
📖 Step-by-Step Solution & Conceptual Rationale:
The epicenter experiences the earliest and often most intense seismic energy arrival.
Sample Question 4
Geophysics & Seismological Surveys HARD • MULTIPLE_CHOICE
In seismic reflection exploration, acoustic impedance (Z) is calculated as:
A Velocity divided by density
B Rock density (ρ) multiplied by seismic wave velocity (V)
C Frequency times wavelength
D Depth times gravity
✓ Correct Answer: B - Rock density (ρ) multiplied by seismic wave velocity (V)
📖 Step-by-Step Solution & Conceptual Rationale:
Reflections occur at boundaries with contrasts in acoustic impedance (Z = ρ * V).
Sample Question 5
Geophysics & Seismological Surveys MEDIUM • MULTIPLE_CHOICE
Electrical resistivity surveying measures subsurface resistance to injected direct electric currents to detect:
A Atmospheric wind
B Groundwater aquifers and mineral veins
C Earthquake magnitude
D Magnetic polarity
✓ Correct Answer: B - Groundwater aquifers and mineral veins
📖 Step-by-Step Solution & Conceptual Rationale:
Water-saturated porous sediments exhibit lower resistivity than dry resistive bedrock.
