Question

What do you mean by waves?

• A. Something that moves through the ocean in response to the forces exerted by the moon and sun.
• B. Continuous, predictable, directional movement of seawater driven by gravity.
• C. Alternate rise and fall of water on the ocean surface.
• D. Continuous, predictable, directional movement of seawater driven by water density.

Answer 1

The correct option is C Alternate rise and fall of water on the ocean surface.

The alternate rise and fall of water on the ocean surface is called waves. Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water.
