Why the question
Growing climate variability and increasing disaster events highlight the importance of understanding interactions between Earth’s spheres in shaping landscapes and hazards.Key Demand of the question
The question requires explaining the interaction between lithosphere and atmosphere and linking it to geomorphic processes. It also demands evaluation of how this interaction contributes to disaster occurrence.Structure of the Answer:
Introduction
Briefly highlight interdependence of Earth’s spheres and its role in shaping landscapes
Body
- Interaction between lithosphere and atmosphere: Role of climatic elements like temperature, rainfall and wind in modifying rocks and landforms
- Impact on geomorphic processes: Influence on weathering, erosion, deposition and landscape evolution
- Relevance in disaster occurrence: Link with hazards like floods, landslides, droughts and glacial events
Conclusion
Emphasise importance of integrated understanding for disaster risk reduction and sustainable planning
