The Peninsular Block

• The northern boundary of the Peninsular block may be taken as an irregular line running from Kachchh along the western flank of the Aravali Range near Delhi and then roughly parallel to the Yammuna and the Ganga as far as the Rajmahal Hills and the Ganga delta.

​

• The northeastern parts are separated by the Malda fault in West Bengal from the Chotanagpur plateau.

​

• Since the Cambrian period, the Peninsula has been standing like a rigid block with the exception of some of its western coast.

​

����» As a part of the Indo – Australian Plate, it has been subjected to various vertical movements and block faulting.��» The Rift valley of the Narmada, the Tapti and the Mahanadi and the Satpura block mountains are some examples of it.��» The Peninsula mostly consists of relict and residual mountains like the Aravali hills, the Nallamala hills, the Javadi hills and the Mahendragiri hills, etc.����

The Thar Desert:�» The Great Indian Desert called as Thar desert is one of the one of the important arid region in the world.��» The whole of the Rajasthan – Sind frontier runs through this region.��» This desert region can be divided into two parts as the great desert and the little desert. ��» Between the great and the little desert lies a zone of absolutely sterile country, consisting of rocky land, cut up by limestone ridges.�

��» The Thar Desert is the world’s seventh largest desert. ��» It forms a significant portion of western India and covers an area of about 200,000 km² to about 238,700 km².��» The Thar desert continues into Pakistan as the Cholistan Desert.��» Most of the Thar Desert is situated in Rajasthan in India, covering about 61 % of its geographical area��» The annual temperatures range from 0º C in the winter to cover 50ºC during the summer.
