Question

Which of the following regions in India is the least vulnerable to landslides?

• A. Uttarakhand Himalaya
• B. Aravali Mountains
• C. Eastern Himalayan Region
• D. Western Ghats

Hint:

For landslide vulnerability in India, remember that the Himalayas and Western Ghats are highly vulnerable, while older and more stable ranges like the Aravalis are comparatively less vulnerable.

Answer 1

The Correct Option is B

Concept: Landslides commonly occur in mountainous regions with steep slopes, heavy rainfall, weak rocks, earthquakes, and human activities like road cutting and deforestation.

Step 1: Understanding landslide-prone regions.
In India, the Himalayas and Western Ghats are highly landslide-prone because of steep slopes, high rainfall, and fragile geology. \[ \text{High landslide risk} \Rightarrow \text{Steep slope + Rainfall + Weak rocks} \]

Step 2: Checking the options.
Uttarakhand Himalaya is highly vulnerable because it lies in the Himalayan region.
Eastern Himalayan Region is also highly vulnerable due to heavy rainfall and steep terrain.
Western Ghats also experience landslides, especially during monsoon.

Step 3: Selecting the least vulnerable region.
Aravali Mountains are old and relatively more stable mountains. They do not experience the same level of landslide vulnerability as the Himalayas or Western Ghats. Therefore, the correct answer is Aravali Mountains.
