Which term refers to the general process of down-slope movement of material due to gravity, including various forms such as slides and creep?

• A. Mass Wasting
• B. Landslide
• C. Slump
• D. Creep

Answer: (A)

Mass wasting refers to the general process of down-slope movement of Earth materials driven by gravity. It isn’t a single event but a broad umbrella that includes many forms, from very slow movements to rapid failures. This concept is useful because it groups together all gravity-driven motions of rock and soil, regardless of speed or specific mechanism, under one term. Why it fits best: the term mass wasting captures the whole spectrum of gravity-driven downslope movement, including slow creep, intermediate-slowness motions like slumps, and rapid events such as landslides and falls. It’s the overarching process that encompasses slides, flows, falls, and creep. Why the other terms aren’t the general concept: a landslide denotes a rapid downslope movement event and is just one type within mass wasting. A slump describes a particular kind of mass wasting where material slides along a curved surface with rotation, not the entire process. Creep refers to extremely slow, gradual downslope movement of soil, also only one specific form.
