Here's a breakdown of why:

* Mass: Refers to the large amount of material involved.

* Wasting: Implies the movement of material downhill, often due to gravity.

Mass wasting encompasses various types of movement, including:

* Creep: Slow, gradual movement of soil or rock.

* Slump: A rotational slide of rock or soil along a curved surface.

* Slide: Movement of material along a plane.

* Flow: Movement of material like a viscous fluid, such as mudflow or debris flow.

* Fall: Freefall of rock or debris from a cliff face.

Mass wasting is a significant natural process that shapes landscapes and can also pose hazards to human infrastructure and safety.
