Growth of native vegetation on slopes
Events that do not typically trigger mass movements include minor policy changes, individual scandals, or isolated incidents that do not resonate with a large portion of the population. Movements usually require a broader issue or grievance that affects a significant portion of society to gain momentum.
One factor that does not commonly trigger mass movement is vegetation cover. In fact, vegetation can help stabilize slopes and reduce the likelihood of mass movement by absorbing water and providing root strength to hold soil in place.
Gravity is the force behind mass movements like landslides and rockfalls. Other factors that can trigger mass movements include heavy rainfall, earthquakes, volcanic activity, human activities like construction or deforestation, and changes in slope stability due to erosion or weathering.
An event that is least likely to trigger a mass movement on a slope is a gradual, sustained increase in temperature without any other contributing factors such as rainfall or seismic activity. This is because temperature alone typically does not have a direct impact on slope stability.
No, slump is not an example of mass movement. Slump is a type of soil movement that involves the downward sliding of a mass of rock or soil along a curved surface. Mass movements usually involve the downslope movement of material under the influence of gravity, such as landslides and rockfalls.

A slump is a mass movement characterized by the downward movement of a coherent mass of rock or soil along a curved surface. It usually occurs on steep slopes or cliffs and is driven by the force of gravity. The movement can be triggered by heavy rainfall, erosion, or changes in slope stability.
Mass movements occur in a cycle of initiation, transportation, and deposition. Initiation involves the factors that trigger movement, such as rainfall or earthquakes. Transportation is the movement of material downslope, and deposition is the settling of material at the base of the slope. Over time, these processes can repeat and lead to further mass movements.
The Coastal Ranges of California have a high incidence of mass movement due to factors such as steep slopes, heavy rainfall, seismic activity, and soil composition. The combination of these factors can trigger landslides, rockslides, and other types of mass movements in the region.
The water content of the soil on a hillside is most likely to trigger a mass movement during heavy rainfall or after a period of prolonged precipitation. This increased water saturation can weaken the soil structure, causing it to become unstable and potentially lead to a landslide or mudslide. Factors such as steepness of the slope, soil composition, and vegetation cover also play a role in determining when a mass movement might occur.
