In the context of geological hazards, which statement about landslides is true?
- Landslides can be entirely prevented through construction.
- They involve the downward movement of various materials due to gravity. (correct)
- They are solely caused by volcanic activity.
- Landslides can occur only in mountainous areas.

Study Notes
Geological Processes
- Shape and alter Earth's landscape over time
- Refer to natural processes
Sinkholes
- Collapse of the ground surface
- Caused by underground voids or weakened areas
- Natural erosion, soil compaction, or human activity can cause formation
Landslides
- Downward movement of rock, soil, or organic material due to gravity
- Major Types:
- Rockfalls
- Slumps
- Flows
- Creep
- Debris Avalanches
Signs & Warnings of Landslides
- Cracks in the ground
- Tilting or leaning of structures
- Changes in drainage patterns
- Sudden appearance of springs
- Trees leaning or tilting uphill
Hydrometeorological Hazards
- Refer to natural atmospheric, hydrological, or oceanographic processes
- Threaten life, property, and the environment
Types of Hydrometeorological Hazards
- Floods:
- Excess water covering normally dry land
- Caused by heavy rainfall, overflowing rivers, or coastal storms
- Droughts:
- Shortage of water supply
- Caused by lack of rainfall and low water levels
- Storms:
- Strong winds, heavy rain, and lightning
- Tropical storms, hurricanes, and tornadoes
- Tsunamis:
- Giant waves caused by underwater earthquakes or volcanic eruptions
- Storm Surges:
- Rise in sea level caused by strong winds during storms
- Coastal Erosion:
- Wearing away of land along shorelines
- Caused by waves, currents, and tides
