Geography for NDA
~10 min read
- What: NDA Geography sits inside Paper II (GAT). It carries roughly ~80 marks across 20 questions in a typical paper, spread over Earth science, climate, India physiography, resources and demography.
- Source base: NCERT classes 6–12 (Physical and Human Geography), plus Indian regional geography. Built from 412 NDA Geography PYQs across 2015–2024.
- How to prepare: Five clusters — Earth as planet, lithosphere, atmosphere & hydrosphere, biosphere, India. Eight weeks at three topics per week covers the syllabus comfortably.
Geography in NDA is one of the most rewarding GAT topics — its content base is finite, the question style is largely factual, and the syllabus has been stable for a decade. Our analysis of 412 PYQs from NDA 2015-I onwards shows the same micro-topics recurring year after year: monsoon patterns, mineral distribution, river systems, soil types, planetary motions, and atmospheric layers.
This hub indexes 23 dedicated topic pages. Each topic page is built from the relevant NCERT chapter plus the PYQs auto-routed to that topic. Start with whichever cluster aligns with your weakest area; complete all five for full coverage.

NDA Paper II — GAT
- Total Paper II marks: 600 (English + GK combined).
- Geography share: 20 questions × 4 marks = 80 marks per paper.

Cluster E — India (6)
Exam Pattern & Weightage
Approximate distribution from NDA 2015-I through 2024-II:
| Cluster | Questions / Paper | Marks |
|---|---|---|
| Earth as Planet | 2–3 | 8–12 |
| Lithosphere (rocks, soil, landforms) | 4–5 | 16–20 |
| Atmosphere & Climate | 3–4 | 12–16 |
| Hydrosphere (oceans, currents) | 1–2 | 4–8 |
| Biomes & Biodiversity | 1–2 | 4–8 |
| India (physiography, climate, resources, agriculture) | 6–8 | 24–32 |
India-specific topics (Cluster E) carry roughly 40% of all Geography marks. Prioritise physiography, monsoon, agriculture and resources first if you have limited prep time.
8-Week Study Plan
Phase 1 — Foundations (Weeks 1–2)
- Week 1: Earth as Planet cluster — shape, motions, latitudes, planets.
- Week 2: Lithosphere cluster — plate tectonics, rocks, weathering, landforms, soil.
Phase 2 — Atmosphere & Oceans (Weeks 3–4)
- Week 3: Atmospheric structure, winds, clouds, world climatic types.
- Week 4: Ocean salinity, tides, currents, oceanic relief. Biomes.
Phase 3 — India (Weeks 5–7)
- Week 5: Physiography and drainage of India.
- Week 6: Indian climate, monsoon, agriculture.
- Week 7: Resources, industry, transport, demography.
Phase 4 — Consolidation (Week 8)
- Full PYQ revision. Timed mocks. Map-work practice (river basins, mineral belts, biome distribution).

Start Free Mock TestFrequently Asked Questions
How many marks does Geography carry in NDA?
About 80 marks (20 questions × 4 marks each) in a typical NDA Paper II GAT section. Negative marking is one-third.
Which is the highest-weightage cluster?
India-specific topics — physiography, monsoon, agriculture, resources, demography. Together they account for roughly 40% of all NDA Geography marks.
How many NCERT books should I read?
Six core books — Class 6–10 social studies (now "Exploring Society"), plus Class 11 and 12 Geography (Physical, Human, India Physical, India People & Economy).
Is map work needed for NDA Geography?
Yes — questions often ask "Which river flows through state X?" or "Which mineral is found in district Y?" An Oxford School Atlas is enough.
How does NDA Geography compare to UPSC Civil Services?
NDA is narrower — only factual MCQs, no descriptive answers. Coverage is comparable to UPSC Prelims but without the conceptual depth that the Mains requires.
What is the best order to prepare the 23 topics?
The 8-week plan above. Earth-as-planet first → lithosphere → atmosphere/oceans → biomes → India. Each cluster builds on the previous one.
