The Main Factor Influencing Slope Stability
Mass wasting events, which involve the downward movement of soil and rock under the influence of gravity, are primarily influenced by several factors. Among these, the angle of the slope and the shear strength of the materials are the most critical.
Angle of the Slope
- The steeper the slope, the greater the gravitational force acting on the materials.
- A slope exceeding the angle of repose (the maximum angle at which materials can remain stable) will likely result in mass wasting.
Shear Strength of Materials
- Shear strength refers to the ability of a material to resist sliding along internal planes.
- Factors affecting shear strength include cohesion (the internal attraction between particles), friction, and moisture content.
- When shear strength decreases (e.g., due to saturation with water), the likelihood of mass wasting increases significantly.
Interactions Between Angle and Shear Strength
- A steep slope with weak materials is particularly susceptible to failure.
- Conversely, a gentler slope with strong materials can remain stable despite a larger mass of material.
Conclusion
In summary, the interplay between the angle of the slope and the shear strength of the materials is crucial in determining slope stability. Understanding these factors is essential for predicting and mitigating the risks associated with mass wasting events, making option 'B' the correct choice.

The angle of the slope and the shear strength of the materials are the main factors influencing slope stability in mass wasting events. When a slope becomes too steep given the existing materials and conditions, it can lead to mass wasting events. The angle of the slope determines how stable the materials are, while the shear strength of the materials determines their resistance to sliding. These factors play a crucial role in determining the likelihood of mass wasting occurrences.
Remember, a steep slope combined with weak materials can make the slope more prone to mass wasting events. The angle and shear strength are key considerations in assessing the potential for slope failure and mass movements.
