The correct answer is: d) All of the above.
Landslides are a type of mass wasting that occurs when a mass of rock, debris, or soil moves down a slope. They can be caused by a variety of factors, including heavy rainfall, earthquakes, and deforestation.
Heavy rainfall can cause landslides by increasing the weight of the soil and making it more likely to slide. Earthquakes can cause landslides by shaking the ground and loosening the soil. Deforestation can cause landslides by removing trees that help to hold the soil in place.
Landslides can be a major hazard to people and property. They can block roads and railways, damage buildings, and even cause deaths. It is important to be aware of the risks of landslides and to take precautions to protect yourself and your property.
Here are some additional information about each of the options:
- Heavy rainfall: Heavy rainfall can cause landslides by increasing the weight of the soil and making it more likely to slide. When the soil becomes saturated with water, it becomes heavier and more difficult to hold in place. This can cause the soil to slide down a slope, resulting in a landslide.
- Earthquakes: Earthquakes can cause landslides by shaking the ground and loosening the soil. When the ground shakes, it can cause the soil to become loose and unstable. This can make the soil more likely to slide down a slope, resulting in a landslide.
- Deforestation: Deforestation can cause landslides by removing trees that help to hold the soil in place. Trees help to hold the soil in place by their roots. When trees are removed, the soil is more likely to slide down a slope, resulting in a landslide.
