In discussing mass wasting, the area of principal concern is Earth's surface rather than its interior. Thus, mass wasting is related most closely to the realm of geomorphology, a branch of physical geology concerned with the study of landforms, with the forces and processes that have shaped them, and with the description and classification of various physical features on Earth. Mass wasting is one of several surficial processes. Other processes of erosion, transportation, deposition - involving streams, glaciers, wind, and ocean waves - are discussed in following chapters. Landsliding is the best known type of mass wasting.
MASS WASTING CONCEPT. The term mass wasting (sometimes called mass movement) encompasses a broad array of processes whereby earth material is transported down a slope by the force of gravity. It is related closely to weathering, which is the breakdown of minerals or rocks at or near Earth's surface through physical, chemical, or biological processes, and to erosion, the transport of material. mass wasting is the geomorphic process by which soil,sand,regolith, and rocks move downslope under the force of gravity without the aid of of transporting medium such as water,ice,wind,

Debris flows. Debris flows are defined as mass‐wasting events in which turbulence occurs throughout the mass.
Varieties of these are called earthflows, mudflows, and debris avalanches. When earth material moves down a hillside as a fluidlike mass, it is called an earthflow.
These flows typically occur in humid areas on steep slopes with thick. Mass wasting, which is synonymous with “slope failure,” is the failure and downslope movement of rock or unconsolidated materials in response to gravity. The term “landslide” is almost synonymous with mass wasting, but not quite because some people reserve “landslide” for relatively rapid slope failures, while others do : Steven Earle.
Mass wasting erosion features exceeding 50 m 2 in a map view were observed in sandstone bedrock at four locations along the coast at Tusan. Information on these locations, dimensions, and key characteristics of the features are presented in Table 4, and shown in Mass wasting book in Fig.
2 B and C. The features are shown in a map view and a cross-section view in Fig. 3, and described briefly herein. Mass wasting is a natural result of weathering on slopes.
Simply put, gravity Mass wasting book loose rock and soil downhill. Mass wasting is the process of erosion whereby rock, soil, and other earth materials move down a slope because of gravitational forces.
It proceeds at variable rates of speed and is largely dependent on the water saturation levels and the steepness of the terrain.

Mass wasting is the downhill movement of rock and soil material due to gravity. The term landslide is often used as a synonym for mass wasting, but mass wasting is a much broader term referring to all movement downslope.
Geologically, a landslide is a general term for mass wasting that involves fast-moving geologic material. CHAPTER 10 MASS WASTING 1. INTRODUCTION Everything at or near the surface of the Earth is pulled toward the Earth by the force of gravity.
(“Gravity: it’s a law you can live with.”) That includes all Earth materials, rock and regolith. This is one of the central concepts of this course.
The landslide of maierato, vibo valentia, Calabria (Italy) Learn here why do mass movements occur. Classification of Mass Wasting: The key criterion for classifying mass wasting is the nature of the movement that takes place. This may be a precipitous fall through the air, sliding as a solid mass along either a plane or a curved surface, or internal flow as a viscous fluid.
The landslides on Giant Mountain are examples of mass wasting. Mass Wasting is the downward movement of rock and soil, often mixed with water. Goodwin explains that when the movement is rapid it can be especially dangerous because they catch people unaware.
Goodwin goes on to explain slump and creep, other types of mass wasting. Start studying Chapter 12 (Chapter 8 in book) Mass Wasting Study Guide.

Delaying mass wasting is a worthy endeavor, of course, because during the time that the measures are still effective they can save lives and reduce damage to property and infrastructure.
The other side of the coin is that we must be careful to avoid activities that could make mass wasting more likely. Classification of Mass Wasting There are three criteria used to classify slope failures: The type of material that failed (e.g., bedrock or unconsolidated sediment), The mechanism of the failure (how the material moved as it failed), and; The rate of movement (how quickly the material moved).Author: Karla Panchuk.

Slope failure, also referred to as mass wasting, is the downslope movement of rock debris and soil in response to gravitational stresses. Three major types of mass wasting are classified by the type of downslope movement.
The types of movement, falls, slides, and flows, will be covered in this module. MHRD NME-ICT The term mass-wasting is used for a broad category of processes whereby the earth’s surface materials are pulled down on a slope by the force of gravity. Mass wasting is a geomorphic process by which soil, regolith, and rock move down a slope under the force of gravity.
It is also called as mass-movement.Mass wasting occurs more readily in rainy seasons for this reason. It turns out that a small amount of water in the soil can aid slope stability because of increased surface tension.
Too much water, of course, eliminates any effects of surface tension.
