Question

question: which type of motion does not contribute to slope failure? answer options: select one of four fall slide flow shear

Explanation:

Slope failure mechanisms include slide (movement along a discrete surface), flow (movement of soil - like a fluid), and shear (failure due to shear stress). Fall is a vertical movement of material from a height and is not a typical contributing motion to slope failure in the context of slope - stability analysis.

Answer:

Fall
