Explain how water content can influence the type and speed of mass movements. Provide examples to support your explanation.

• Water increases cohesion, slowing down movements like landslides.

• Water acts as a lubricant, increasing the speed of movements like mudflows.

• Water has no effect on mass movements.

• Water only affects movements in cold climates.

How does the angle of repose affect the likelihood of mass movements?

• A steeper angle of repose decreases the likelihood of mass movements.

• A steeper angle of repose increases the likelihood of mass movements.

• The angle of repose has no effect on mass movements.

• The angle of repose only affects mass movements in coastal areas.

Evaluate the role of human activities in triggering mass movements. Provide examples to illustrate your points.

• Human activities have no effect on mass movements.

• Deforestation and construction can destabilize slopes, leading to mass movements.

• Human activities only prevent mass movements.

• Urbanization has no impact on slope stability.

Propose strategies to mitigate the risks associated with mass movements in vulnerable areas.

• Ignore the risks and continue development.

• Implement land-use planning, reforestation, and engineering solutions like retaining walls.

• Only rely on insurance to cover damages.

• Evacuate all areas permanently.

Analyze the impact of vegetation on the stability of slopes and the occurrence of mass movements.

• Vegetation destabilizes slopes by adding weight.

• Vegetation stabilizes slopes by anchoring soil with roots.

• Vegetation has no impact on slope stability.

• Vegetation only affects slope stability in desert regions.

Describe the process of solifluction and identify the conditions under which it typically occurs.

• Solifluction occurs in arid regions with high temperatures.

• Solifluction involves the slow, downslope flow of water-saturated soil in permafrost areas.

• Solifluction is a rapid movement of dry soil and rock.

• Solifluction only occurs in tropical rainforests.
