equifinality The theory that the members of morphologically similar land-forms may each have been produced by a different process or sequence of processes. For example, an armchair-shaped hollow may have been produced by a cirque glacier, by a rotational landslide, by nivation, or by spring-sapping. Their present-day similarity may make the origin of such land-forms difficult to determine.
