is bigger than most of European counties put together.

mineral deposits.
Capital city - Jaipur
Area - 3,42,23,974 Square Kilometres (1,32,152 sq. miles)
Physical features - Rajasthan is separated from the Ganga basin by
the watershed of the Aravalli Mountains.
This runs from the northeast to the southwest and is displaced by a deep
fault, which moved the mountains some 1,225 km (765 miles) in its central
position and 300 km (190 miles) in its eastern portion near Delhi

The
topographical regions into which Rajasthan can be divided are the
northeastern hill tract, the Vindhyan plateau extensions in the southeast,
the basins of the Chambal and Banas, the Aravalli backbone, the Shekhawati
uplands in the northwest and the Luni basin of the southwest, merging into
the large area on the west - the desert which occupies some 213,000 sq. km
(82,000 sq. miles).
Travel across this varied landscape usually begins from the east since most
people enter Rajasthan from Delhi, which lies in the Jaipur- Delhi saddle
between Rajasthan and the Ganga plain.

society.
