Question

What is the chance of occurrence of landslides in Chhotanagpur Plateau?

• A. High to very high
• B. High
• C. Medium to high
• D. Low

Hint:

Landslide risk is highest in steep and fragile mountain areas like the Himalayas and Western Ghats. Plateau regions like Chhotanagpur generally have lower landslide risk.

Answer 1

The Correct Option is D

Concept: Landslide occurrence depends on slope, rainfall, geology, weathering, vegetation cover, and human disturbance.

Step 1: Understanding landslide susceptibility.
Regions with steep slopes, weak rocks, heavy rainfall, and high seismic activity generally have high landslide risk. \[ \text{High landslide risk} = \text{Steep slopes + Heavy rainfall + Weak geology} \]

Step 2: Comparing Chhotanagpur Plateau with highly prone regions.
The Himalayas and Western Ghats are more landslide-prone because of their steep slopes and high rainfall. Chhotanagpur Plateau is comparatively stable and does not have the same level of landslide susceptibility.

Step 3: Selecting the correct category.
Since Chhotanagpur Plateau has comparatively lower landslide vulnerability, the chance of occurrence of landslides is low. Therefore, the correct answer is Low.
