The other common mechanisms are conduction (e.g., electric currents) and convection (e.g., the bulk motion of boiling water in a pot), but we will not discuss these other mechanism here, only waves, also known as radiation. Ex. As an example for the creation of a disturbance at one place, having a remote effect, consider a dog. You step on its tail, and then, on the other side of the dog, it barks.
