MCQs
1. What happens to the soil during a landslide?
A) It becomes more stable
B) It becomes loose and unstable
C) It becomes harder
D) It becomes lighter
Answer: B) It becomes loose and unstable
Explanation: The soil becomes loose and unstable, causing it to move downhill.
2. When can landslides occur?
A) After heavy rainfall
B) During a drought
C) In the middle of winter
D) During a heatwave
Answer: A) After heavy rainfall
Explanation: Landslides are more likely to occur after heavy rainfall, when the soil becomes saturated with water.
3. What can trigger a landslide?
A) Earthquakes
B) Thunderstorms
C) Volcanic eruptions
D) All of the above
Answer: D) All of the above
Explanation: Earthquakes, thunderstorms, and volcanic eruptions can all trigger landslides.
4. What moves downhill during a landslide?
A) Trees
B) Rocks and debris
C) Buildings
D) Animals
Answer: B) Rocks and debris
Explanation: Rocks and debris are carried downhill during a landslide, causing damage to anything in their path.
5. What can help prevent landslides?
A) Planting trees
B) Building retaining walls
C) Removing vegetation
D) Digging trenches
Answer: B) Building retaining walls
Explanation: Building retaining walls can help prevent soil from becoming loose and unstable, reducing the risk of landslides.

Answer: precautions
5. Landslides can cause damage to homes, roads, and other __________.
Answer: structures
True / False
1. Landslides only happen in areas with steep slopes (True / False)
False. Landslides can happen in any area where the soil becomes saturated and unstable, not just on steep slopes.
2. Landslides are always caused by earthquakes (True / False)
False. While earthquakes can trigger landslides, they can also be caused by heavy rainfall, snowmelt, or volcanic activity.
3. Trees and vegetation can help prevent landslides (True / False)
True. The root systems of trees and vegetation help hold soil in place, reducing the risk of landslides.
4. Landslides only occur in rural areas (True / False)
False: Landslides can happen in both rural and urban areas, especially in areas where there is construction on or near slopes.
