  • 2. 

    Spreading oil on the open sea has the effect of __________.

    • A.

      Lengthening the distance between successive crests

    • B.

      Increasing the height of the seas

    • C.

      Preventing the wave crests from breaking

    • D.

      Diminishing the height of the seas

    Correct Answer
    C. Preventing the wave crests from breaking
    Explanation
    When oil is spread on the open sea, it forms a thin layer on the surface of the water. This layer acts as a barrier, preventing the wave crests from breaking. Normally, when waves approach the shore, they break and release their energy. However, the presence of oil disrupts this process by reducing the friction between the water molecules, making it harder for the waves to break. As a result, the wave crests remain intact and do not break, thereby preventing the energy release and reducing the overall height of the seas.
