Topic: changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes
Q2. Explain the geomorphological significance of the Aravalli range in the north-western Indian landscape. Analyse how human interventions have altered this role. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question
Due to increasing ecological stress on the Aravalli range from mining, urban expansion and regulatory ambiguities, which makes understanding its geomorphological role in north-western India crucial.Key Demand of the question
The question demands an explanation of the geomorphological significance of the Aravalli range in shaping the north-western Indian landscape and an analysis of how human interventions have altered this role.Structure of the Answer
Introduction
Briefly introduce the Aravalli range as one of the oldest fold mountain systems and highlight its importance in a semi-arid geographical setting.Body
- Explain the geomorphological significance of the Aravallis in terms of climatic moderation, drainage control, groundwater recharge, soil stability and micro-climatic influence.
- Analyse the impact of human interventions such as mining, urbanisation, deforestation, infrastructure development and policy dilution on these geomorphic functions.
Conclusion
Conclude by stressing the need for geography-informed and landscape-level protection to sustain the long-term geomorphological role of the Aravalli range.
