Indian Geography and Economy
Geography
Expect physical, Indian and world geography: rivers, mountains, climate, soils, crops, minerals, industries, population and transport.
- Rivers: the Ganga begins as the Bhagirathi at Gangotri, the Yamuna at Yamunotri, and the Brahmaputra enters India as the Tsangpo from Tibet. The Ganga is the longest river within India.
- Kanchenjunga is India’s highest peak; the Western Ghats are a biodiversity hotspot.
- UP specifics: most populous state, largest producer of sugarcane and wheat, minerals in Sonbhadra, and the Gangetic plain as its core.
- Soils: alluvial is the most extensive, black soil suits cotton in the Deccan, plus red and laterite soils.
Economy
Basics of national income, inflation, banking, budget, taxation, agriculture and welfare schemes.
- GDP is measured at market prices; the RBI regulates money supply and sets the repo rate.
- Inflation is tracked through CPI (retail) and WPI (wholesale).
- Direct taxes: income tax and corporate tax. Indirect: GST.
- Repo rate is what the RBI charges banks; the reverse repo is what it pays them.
Worked example
“Which state leads India in wheat production?” Wheat needs cool winters and assured irrigation, which fits the Punjab–Haryana–UP belt. UP has the largest area and output, so the answer is Uttar Pradesh; Punjab leads in yield per hectare, which is the usual distractor.
Traps that cost marks
- Confusing highest production with highest productivity.
- Mixing the source of the Ganga (Gangotri) with its mouth (Sundarbans delta).
- Swapping the repo and reverse repo definitions.
- Treating the Western Ghats as an extension of the Himalayas.
