Why is there sometimes wire mesh covering a steep slope? What are the characteristics of the type of
mass wasting this is meant to prevent? What will be an ideal response?
Wire mesh is put on slopes to prevent dislodged rocks from falling onto the road below. Rockfalls
result from failure of bedrock along joints or bedding planes and occur because the slope has been
undercut (often by building the road). Rocks can be small to massive and can even bury towns
