Question

     Which statement provides the most accurate information

    about earthquake waves? 
    A P-waves are responsible for creating density differences in the material they pass through. Correct Answer Incorrect Answer
    B The shadow zone of S-wave is smaller as compared to the P-waves. Correct Answer Incorrect Answer
    C Body waves are the most damaging of all the earthquake waves. Correct Answer Incorrect Answer
    D Most of the earthquake waves vibrate parallel to the direction of wave propagation. Correct Answer Incorrect Answer

    Solution

    The shadow zone of P-waves is in the form of a band between 105 to 145 degrees while that of S-waves is all areas beyond 105 degrees. Thus, the shadow zone of S-waves is much larger than the P-waves. Surface waves are the most damaging waves in terms of losses caused to the life and property of the people. Most of the Earthquake waves vibrate in the direction perpendicular to the direction of the propagation of the waves.
