Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.
In medicine, a condition is considered asymptomatic if the patient is a carrier of a disease or infection but does not experience symptoms. A condition can be asymptomatic if it does not present the noticeable symptoms with which it is normally associated. Asymptomatic infections are also called subclinical infections. Other conditions (such as mental illness) may be considered subclinical if they present some but not all of the symptoms required for a clinical diagnosis. The term clinically silent is also used.
