Waves: fifth question

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not completely submerged and why the middle of the ocean has not yet been depleted of its water supply.

  1. Ocean waves do not transport water. Ocean waves can only bring energy to the shore; water particles simply oscillate about their fixed position. As such, water does not accumulate on the beach.

  2. Particles have a fixed position and they can only oscillate so there is not a water transport. I agree with Beatrice

  3. I agree with Martina and Beatrice because the water waves don't transfer matter, they bring energy. Water particles simply oscillate, but they have a fix position. Therefore water doesn't pile up on the shore.

  4. In the ocean waves motion there isn't any transferring of water but there is just a generation of energy. In fact water particles oscillate on their fixed position and so the level of the water on the shore remains quite always the same.

  6. Because even though there is a force acting on the water, the particles are still. The only displacement we can see is the one generated by the energy transfer and that's what we call waves. These ones, since they have an oscillation, behave like other kinds of wave and so after a displacement, they come back to the original point.

  7. The particles of water are still. There is no water transport by The waves that are the only movement se can see. Se can just say that water particles oscillate however Being in fix position. Because of that The beach isn't completely submerged and The middle of the ocean has't yet been depleted of its water supply. Dughetti
