Q. Consider the following geological events:

1. Slight tilting of the Peninsular block from northwest to the southeastern direction
2. Upheaval of the Himalayas
3. Subsidence of the western flank of the Peninsula

Which of the above is/are the major geological events responsible for the drainage pattern in Peninsular India?
Answer: All of the above
Notes: The drainage pattern of Peninsular India is primarily shaped by three key geological events: (1) the slight tilting of the block from northwest to southeast, (2) the upheaval of the Himalayas, and (3) the subsidence of the western flank. These processes together determined the orientation, flow, and rejuvenation of major river systems in this region.
