Weathering, Soil, and Mass Wasting
begins with a brief examination of the external processes of weathering, mass wasting, and
erosion. The two forms of weathering, mechanical and chemical, are investigated in detail –
including the types, conditions, rates, and net effect of each. The soils section of the chapter begins
with a description of the general composition, texture, and structure of soil. After examining the
factors that influence soil formation, development, and classification, soil erosion, as well as some
ore deposits produced by weathering, are presented. Mass wasting begins with a look at the role the
process plays in landform development. Following a discussion of the controls and triggers of mass
wasting, a general presentation of the various types of mass wasting concludes the chapter.
Objectives To ponder:
After the reporting, this is expected from you:
Be able to know the processes of weathering, soil, erosion, and mass wasting.
Be able to differentiate mechanical from chemical weathering.
To learn the soil composition, structure, texture, classification
Identify the controls of mass wasting.
Know the various types of mass wasting.
Summary Of the Report
– the disintegration and decomposition of rock at or
near the surface, 2)
– the transfer of rock material downslope under the influence of
gravity, and 3)
