Why do water wave crests die down as they move away from the disturbance that created the wave?

Water wave crests decrease in height when they are observed farther from the source because the energy that was used to create them is being distributed over a broader front. A rock thrown out into a lake creates a disturbance, and the wave travels out across the lake in all directions. As it moves farther out into the lake, a larger and larger area of water is carrying the energy. A fixed or finite amount of energy was initially delivered. The more area the wave covers, the more the energy must be distributed across the area. That means the amplitude of the wave in a given place far from the point of origin will have to be lower.

Does a periodic disturbance of a medium describe a wave?
No. If it happens that the disturbance propagates through the medium, i.e. spreads out from the disturbed point, then the phenomenon that travels away from the disturbance and through the medium describes the wave.
What moves in a wave?
The term "forward" is arbitrary. The waves propagate away from the energy source that created them or away from a reflective surface. In mechanical waves (such as ocean waves), the waves move through the medium (water), but the particles in the medium do not travel along with the waves, although they do oscillate in place as the wave passes through the medium.
A ship anchored at sea is rocked by waves that have crests 14 m apart The waves travel as 7.0 ms How often do the wave crests reach the ship?
A wave crest hits the ship. The next wave crest is 14 m away and it is traveling at 7 meters per second. So in two seconds it will travel 14 m . Similarly, the next wave crest will hit in two seconds etc. So the crests hit the ship every two seconds.
When was Float Away Deconstructed created?
Float Away Deconstructed was created in 2005.
How do vibrations in materials set up wave disturbance that spread away from the source?
If you drop a rock in a pond waves from the rocks splash carry energy away from the splash,if you there is something near the wave splash the object will NOT travel with the energies direction it will only go up and down
A blank is a disturbance that moves away from its starting point?
It is a wave

What can cause emotional disturbance?
