A video about a landslide demonstrates which main idea in geography?

• A. Weather patterns
• B. Mountains
• C. Population size
• D. Erosion and natural hazards

Answer: (D)

Erosion and natural hazards describe how landscapes are shaped by natural forces and how those forces can create danger. A landslide video shows rock, soil, and debris slipping down a slope, which is erosion in action as material is moved from where it sits to a lower spot. It’s also a natural hazard because landslides can threaten people and property. So the scene illustrates both the shaping of the land through moving material and the risk that such movements pose. Weather patterns deal with atmospheric conditions, not the movement of earth; mountains are a landform, not the process of wearing away or a hazard; population size concerns people rather than geological processes.
