Statements 'A' and 'B' both are correct Explanation & Key Takeaways: • Himalayan rivers cross many Himalayan ranges and the Shivalik Hills and enter into the plain area. Hence statements A is correct. Important Notes: • Shiwalik Range • Also known as Outer Himalayas. • Located in between the Great Plains and Lesser Himalayas. • The altitude varies from 600 to 1500 meters. • It has a length of about 2,400 km from the Potwar Plateau to the Brahmaputra valley. • The southern slopes are steep while the northern slopes are gentle. • Peninsular river • The Peninsular drainage system is older than the Himalayan one. • This is evident from the broad, largely-graded shallow valleys, and the maturity of the rivers. • The Narmada and the Tapi are the peninsular rivers that flow through a rift valley. • Most of the major Peninsular Rivers except Narmada and Tapi flow from west to east. • Mahanadi, Godavari, Tungabhadra, Kaveri in the Deccan the gradient flows from West at the height of Western Ghats to the East into the Bay of Bengal. • The geological faults (rifts) created between two ancient mountain ranges, ‘Vindhya’ & ‘Satpura’, when the Indian plate moved into the Eurasian plate. • They arise in the Chota Nagpur plateau in the east of the Deccan peninsula and from there, the gradient is down towards the Arabian Sea in the West; that is why they travel from the east to the west. • These faults run parallel to the Vindhyas and the Satpuras.
