Waves occur everywhere, as it is the most basic form of energy transfer in the universe.
There are two types of waves: Electromagnetic, and mechanical waves. The difference is that electromagnetic waves can travel through vacuum, while a mechanical wave need a medium to propagate.
What causes them?
I really won't go in detail, but this should answer your question: Disturbance in space-time caused by transfer of energy

Waves can originate from many sources.
Some common sources are from vibrations from
collisions, natural radioactivity, and electricity/magnetic.
Collisions are fairly obvious, but they include the
waves created that propagate in air. Natural radioactivity
is firing of electrons an protons in chemical and nuclear
reactions which can occur as the result of unstable
isotopes. Electromagnetic waves can be created
by a moving electric charge.

disturbance causes waves and they can occur anywhere

Actually, waves are energy. It is energy that moves across the ocean's surface.

Usually the wind does.
