SHORTCUT
Rivers and where they rise
Sort them by which way they flow, and the map does the remembering.
The question
Which is the longest river in India, and where does it rise?
The trick
Split India's rivers into two families: Himalayan rivers, which are snow-fed and flow all year, and peninsular rivers, which are rain-fed and flow only in season.
Worked example
- 1Himalayan: Ganga (Gangotri glacier), Yamuna (Yamunotri), Indus and Brahmaputra (both rise in Tibet)
- 2Peninsular flowing east into the Bay of Bengal: Godavari (Trimbakeshwar), Krishna (Mahabaleshwar), Kaveri (Talakaveri)
- 3Peninsular flowing west into the Arabian Sea: Narmada and Tapti — the two odd ones out
So: The Ganga, rising at the Gangotri glacier
