One good defense against mass-wasting damage on a hillside is to ____.
A) clear away all the trees and shrubs on upper parts of the hill
B) saturate the slope with water
C) bulldoze away lower parts of the slope
D) study an area's geology and history to determine if mass wasting has occurred on similar nearby slopes

Question

Quizplus · Accepted Answer

Studying an area's geology and history to determine if mass wasting has occurred on similar nearby slopes can help identify the potential for mass-wasting damage and allow for preventative measures to be taken, such as avoiding construction on unstable slopes or implementing erosion control measures like retaining walls or vegetation cover. Clearing away trees and shrubs can actually increase the likelihood of mass wasting by removing root systems that hold soil in place, saturating the slope with water can increase the weight and instability of the slope, and bulldozing away lower parts of the slope can destabilize the entire hillside.
