GEOLOGY

Detailed explanation-1: -Waves are nothing but the oscillatory movements that result in the rise and fall of water surface. Waves are a kind of horizontal movements of the ocean water. They are actually the energy, not the water as such, which moves across the ocean surface. This energy for the waves is provided by the wind.

Detailed explanation-2: -Trochoidal motion of wind waves. While one normally associates an up and down motion with the passage of each wave. Actually, a circular motion occurs. It is this orbital motion of the water (or objects on the surface of the water) that causes an object to bob up and down, forward and backward as waves pass under it.

Detailed explanation-3: -The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide. Movement of water caused by meteorological effects (winds and atmospheric pressure changes) are called surges. Surges are not regular like tides.
