Keywords: "mass wasting", slope, construction, "glacial valley", riverbank, shore, wave, cliff, human

Our transcription: Land has always been a valuable commodity.
Some want it simply as a place to live; others are more interested in developing it for profit, but regardless of motive, anyone about to undertake a building project needs at least a fundamental understanding of how mass wasting operates.
A number of factors contribute to mass wasting processes.
One of the most important is the angle of a given slope.
Some slopes are naturally steep, such as those along glacial valleys, riverbanks, or at the shore where waves cut back the cliffs, but in many areas the primary force responsible for steeping the slopes is human activity.
