Landslides are a common hazard in Nagaland due to:

The correct answer is: d) All of the above

Landslides are a common hazard in Nagaland due to the following reasons:

• Heavy rainfall: Nagaland is a state in northeastern India that receives an average annual rainfall of over 2,000 mm. This heavy rainfall can cause landslides by loosening the soil and making it more susceptible to erosion.
• Steep slopes: The terrain in Nagaland is characterized by steep slopes, which are more prone to landslides than gentle slopes.
• Deforestation: Deforestation can also contribute to landslides by removing trees that help to hold the soil in place.

When these factors combine, they can create a perfect storm for landslides. In recent years, there have been several major landslides in Nagaland, including one in 2014 that killed at least 40 people.

Landslides can have a devastating impact on communities, causing loss of life, property damage, and disruption to livelihoods. It is important to take steps to mitigate the risk of landslides, such as planting trees, terracing hillsides, and building retaining walls.
