Which of the following seismic waves travels fastest through the Earth's interior? A. S-wave B. P-wave C. Love wave D. Rayleigh wave

medium MCQ 2 marks Class 7 · Geography · Our Changing Earth
  1. A. S-wave
  2. B. P-wave
  3. C. Love wave
  4. D. Rayleigh wave
Answer
B. P-wave

The correct answer is B. P-wave — Select option B.

Step-by-step solution

  1. Recall the four primary seismic wave types: Primary (P) wave, Secondary (S) wave, Love wave, Rayleigh wave.
  2. Know that the P-wave is a compressional wave that moves through both solids and liquids, making it the fastest.
  3. Therefore the fastest wave is the P-wave.
  4. Select option B.
Common mistake: Confusing P-wave with S-wave

Concept tested: Seismic wave speed
