MASS WASTING PROCESSES

1 The downslope movement of rock, mud, or other material under the influence of gravity is known as mass wasting. While the angle of the slope is a major factor in the potential for mass wasting, the slope is not the sole determiner of mass wasting events. Water plays a significant role, especially where it is plentiful during the rainy season. Earthquakes may cause rockslides, mudflows, and other mass movements. Factors such as the presence or absence of vegetation and human activities can also influence the potential for mass wasting.
2 One way to classify mass wasting processes is on the basis of the material involved, such as rock, debris, earth, or mud. The manner in which the material moves is also important and is generally described as a fall, a slide, or a flow. A fall occurs when weathering loosens boulders from cliffs or rock faces, causing the boulders to break away and fall. A slide takes place whe
A. result
B. consistency
C. mudflow
D. mixture

Arms. (46) If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. (47) If someone upsets you, just cross your arms to show you’re unhappy!
