[EXAMINER REASONING]

1. Trap: Confusing geomorphic/climatic processes or misidentifying map locations. Examiners test precise terminology and spatial reasoning.
2. Most confused: The distinction between process (how it works) and pattern (where it occurs), and between natural and human-induced geographic phenomena.
3. Key anchor: The fundamental geographic concepts (location, place, region, movement, human-environment interaction) and mechanisms (endogenic/exogenic forces, atmospheric circulation, hydrological cycle).
4. Current affairs hook: Climate change impacts, extreme weather events, new infrastructure projects, disaster events, satellite data updates, Census 2026 (delayed).
5. Mains hinge: Frame answers around the core tension - determinism vs possibilism, conservation vs development, uniformitarianism vs catastrophism, regional disparity vs national integration.

Core Concept

Drainage System of India is a core topic in Indian physical/human geography. It integrates geomorphology, climatology, and human-environment interaction. For UPSC, this topic tests both factual knowledge (locations, names, data) and conceptual understanding (processes, patterns, cause-effect relationships).

Map-based questions are frequent - aspirants must locate features on outline maps. The topic connects to agriculture, industry, transport, urbanization, disaster management, and environment. Climate change adds a dynamic dimension to traditionally static geographic concepts.
