Notes

cause and effects of landslide (bing):
Landslides are mass movements of soil, rock, or debris down a slope. They can be caused by heavy rains, earthquakes, deforestation, volcanic eruptions, or human activities. Landslides can have negative impacts on the environment, infrastructure, and human lives. They can damage roads, buildings, houses, and crops. They can also create floods, block rivers, and trigger more landslides. Landslides can kill or injure people and animals

CAUSE:
- Increase in water content or saturation by rain water infiltration, snow melting, or glaciers melting, which reduces the friction between the bedrock and the overlying sediment.
- Rising of groundwater or increase of pore water pressure, which weakens the cohesion of the soil.
- Increase of hydrostatic pressure in cracks and fractures, which creates tension and reduces the strength of the rock.
- Earthquakes, which disrupt the force of friction holding sediments in place on an incline

cause and effects of avalanche (bing):
Factors influencing avalanches include slope, snowpack, and triggers such as weather conditions or human activity. Avalanches can be dangerous and deadly, affecting infrastructure, transportation, and the environment. Avalanches are large amounts of snow that barrel down slopes at rapid speeds.

CAUSE:
- Heavy Snowfall Heavy snowfall leading to snow accumulation on slopes is one of the basic requirements for the occurrence of an avalanche.
- Wind Direction The direction in which the wind blows also determines the pattern of snow accumulation on the slopes.
- Layering of Snow
- Steeper Slopes
- Higher Temperatures
- Earthquakes
- Movements Or Vibrations Produced By Machines And Explosives
- Deforestation
