Northward movement of the Indian subcontinent towards the Eurasian plate eventually caused a massive collision and the creation of the Himalayan range. This cataclysmic event was orchestrated by the following geodynamic processes:This cataclysmic event was orchestrated by the following geodynamic processes:
1. Continental convergence: The shear movement observed in the Indian plate toward the Eurasian plate meant there was going to be a compression zone.
2. Crustal thickening: When the plates came into contact, the crust rises and becomes thicker creating an extensive orogenic belt.
3. Faulting and folding: To worsen the effects of the forces that caused uplift, there was faults which led to folds that shaped the Himalayan range.
4. Uplift and metamorphism: This underthrusting made the rocks in the region to uplift and metamorphose quickly due to movements on the Indian plate which subducts beneath the Eurasian plate.
5. Denudation and erosion: Weathering and erosion contributed to the rock break down thus revealing the towering giants of the himalayas.
This titanic story has been playing out on a scale of tens of millions of year constructing one of the most grandiose mountain chains possible on this planet. Himalayas is one of the best examples of the geodynamic forces that are still active and creating miracles on this earth.

Model Answer
Introduction
Landslides are natural disasters where earth or rock masses move downhill due to gravity, frequently occurring in regions like the Himalayas and the Western Ghats of India. Understanding the causes of these landslides is crucial for disaster management and mitigation.
Causes of Landslides in the Himalayan Region
1. Geological Causes
2. Climatic Causes
3. Human Causes
Causes of Landslides in the Western Ghats
1. Geographical Causes
2. Climatic Causes
3. Human Causes
Conclusion
While both the Himalayan region and the Western Ghats face landslides due to geological, climatic, and human factors, the specific causes differ based on their unique geographical features and human activities. Understanding these distinctions is vital for effective disaster management strategies.
