Water waves are disturbances that travel through water, caused by energy moving through the liquid. They can be generated by various factors, such as wind, earthquakes, or objects entering the water. The movement of water waves is characterized by a series of crests (the highest points) and troughs (the lowest points), creating a rhythmic pattern. These waves can vary in size and strength, depending on the energy source. For example, ocean waves are typically larger and more powerful than ripples created by a gentle breeze. Understanding water waves is essential for activities like surfing, boating, and coastal management.
