Rajasthan General Knowledge
Rajasthan General Knowledge in the CHO paper tests physiography, drainage, climate, minerals, administrative change and tourism geography, usually as one-mark factual recall. The section rewards precise numbers and locations, not general impressions.
Physical frame
- The Aravalli range runs south-west to north-east and separates the arid west from the semi-humid east; Guru Shikhar on Mount Abu (1,722 m) is the highest peak.
- The Thar occupies the west and its drainage is largely internal; the Luni is the main desert river and drains towards the Rann of Kutch.
- The Chambal is the state's perennial river; the Banas is the longest river flowing entirely within Rajasthan.
- Sambhar is the largest inland saline lake; Keoladeo Ghana near Bharatpur is a Ramsar wetland and bird habitat.
Resources and administration
- The Indira Gandhi Canal commands the north-west and shifted cropping towards wheat, mustard and cotton.
- Rampura Agucha is a major zinc-lead mine; Makrana supplies marble; Jhamarkotra supplies rock phosphate; lignite comes from the Barmer-Bikaner belt.
- District numbers have changed repeatedly since 2023, so answer from the latest notification rather than memory.
Worked example
A question asks for the highest peak of the Aravallis. Reason: the range's summit is Guru Shikhar on Mount Abu in Sirohi district, 1,722 m. If the wording is 'highest point in Rajasthan', the same answer applies because no other range exceeds it.
Traps
Do not confuse Sambhar with Pushkar; do not call the Banas perennial; do not use old 33-district lists; check whether a question asks river length within the state or total course.
