Explanation:
Waves can be defined as the movement of water molecules caused as a result of the disturbance generated by the wind blowing over the surface of a sea or ocean.
Basically, waves can only transfer energy over a distance from one point to another without moving matter such as a boat.
This ultimately implies that, a wave can only move an energy but do not move matter.
1. Waves are made by wind pulling on the surface of the water.
2. The length of water over which the wind blows is called the fetch.
3. Large waves are made by strong wind.
4. The wind blowing for a long time is known as long fetch.
6. The water that goes up the beach is called swash.
7. The water that goes down the beach is called backwash.
8. Tides are caused by the pull of the sun and moon.
