    Consider the following statements: 1. Tsunamis have very short wave length and high amplitude in the deep sea. 2. As the tsunamis reach the coast, their wave length increases and amplitude decreases. Which of the above statements is/are correct?

    A)  1 only                         

    B)  2 only

    C)  Both 1 and 2                

    D)  Neither 1 nor 2

    Correct Answer: D

    Solution :

     In the deep sea, tsunamis have very long wave length which often exceeds 500-700km. But their amplitude is very low and rarely exceeds 1 meter. However, on reaching coast, wave length of tsunamis is reduced considerably and their amplitude increase to 10-30 meters.
