The waves always rise and fall on the surface of the ocean water. According to Richard, “Waves are the turbulence of the liquid surface of the ocean.” This is the most extensive and ubiquitous motion of the ocean water.
There are two main causes of the origin of ocean waves:
1. By the blowing of winds.
2. When water surface becomes wavy by the motion in the earth’s crust.
Waves are the rocky motion on the ocean surface. In this, the water level of ocean rises up and falls down, but water does not move from its place to another place. If a floating object (like : a piece of wood) is thrown at the water level, then it will sway back and forth, up and down at its own place, while the waves will appear flowing further.
