Answer:
B. Geological
Read Explanation:
Geological disasters are a type of natural disaster that originate from the processes and movements within the Earth's crust and beneath its surface.
Landslides: These involve the movement of a mass of rock, debris, or earth down a slope. They are driven by gravity and often triggered by factors like heavy rainfall, earthquakes, volcanic eruptions, or human activities that destabilize slopes.
Mudflows (or Debris Flows): These are a more fluid type of landslide, consisting of a fast-moving mixture of water, soil, rock, and other debris. They typically occur on steep slopes and are often triggered by intense rainfall or rapid snowmelt, saturating the ground.
Both landslides and mudflows are direct consequences of the dynamic geological processes of the Earth, making them distinct categories within natural hazards. They result from the instability of earth materials on slopes, a core aspect of geological science.
