What causes a disturbance that results in a wave?

Many factors can cause disturbance that results in a wave.
For example, the waves created in sea are due to the gravitational pull of attraction between Earth and moon. Human activities are also responsible(huge ships). The air above the surface of sea can also cause waves. In case of electromagnetic field, electromagnetic waves are created because of acceleration of charged particles.

Wave is the propagation of disturbance from place to place is a regular and organised way. The disturbance like friction between wind and surface water and Gravitational pull of attraction between Earth and moon also create waves.

Wave is the propagation of disturbance from place to place is a regular and organised way.

Examples:

Gravitational pull of attraction between Earth and Moon.Surface waves, are created by the friction between wind and surface water.Electromagnetic waves are created because of acceleration of charged particles.

Hence we can conclude that the disturbance like friction between wind and surface water and Gravitational pull of attraction between Earth and moon also create waves.

“when two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. when an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. this process is called subduction. “ i found this on google i hope it
