A ripple effect is a situation in which, like ripples expanding across the water when an object is dropped into it, an effect from an initial state can be followed outwards incrementally.
In sociology, the Ripple effect can be observed in how social interactions can affect situations not directly related to the initial interaction,[page needed] and in charitable activities where information can be disseminated and passed from community to community to broaden its impact.
