Step 1
The impact of human activities on mass movement processes
Answer
Human activities, such as deforestation, mining, and urban development, can significantly influence mass movement processes, often increasing the risk of landslides and soil erosion.
-
Deforestation: The removal of trees weakens the soil structure, reducing its stability and increasing susceptibility to landslides.
-
Construction and Urbanization: Building on slopes without proper engineering can destabilize land and lead to landslides. Moreover, the alteration of natural drainage patterns can exacerbate the risk of mass movement.
-
Agricultural Practices: Intensive farming and overgrazing can degrade soil health, leading to increased erosion and mass movement events.
-
Example and Diagram: An example of this is seen in the effects of logging on the slopes of the Appalachian Mountains, where landslides have increased due to strip logging.
(The diagram would highlight the relationship between deforestation and landslide occurrence.)
