- The northward movement of the Indian plate is continuing and it has significant consequences on the physical environment of the Indian subcontinent.
- The Peninsula stands erect, with some exceptions on its western coast, which is under the sea and some other parts also changed because of tectonic activity. This does not affect the original basement.
- The Peninsula is a part of the Indo-Australian Plate, with various vertical movements and block faulting. Some examples are the rift valleys of the Narmada, the Tapi and the Mahanadi and the Satpura block mountains.
- The river valleys here are shallow with low gradients.

The Correct Answer is Option 'A'
Explanation:
Statement 1: The northward movement of the Indian plate continues to date.
The Indian Plate is a major tectonic plate located in the northern hemisphere. It is currently moving northwards at a rate of approximately 5 centimeters per year. This northward movement is primarily caused by the subduction of the Indian Plate beneath the Eurasian Plate.
The Indian Plate is colliding with the Eurasian Plate along the Himalayan mountain range, resulting in the formation of the Himalayas. This collision is responsible for the ongoing upliftment and formation of new mountains in the region.
Therefore, statement 1 is correct.
Statement 2: A part of the Western peninsular region of India is submerged beneath the sea.
The Western Peninsular region of India is a part of the larger Deccan Plateau. It is primarily composed of hard basaltic lava flows that were erupted during the Cretaceous period. These lava flows have been extensively eroded by rivers over millions of years, resulting in the formation of a vast plateau.
The Western Peninsular region is not submerged beneath the sea. Instead, it is characterized by its elevated topography, with the average elevation ranging from 600 to 900 meters. The region is home to several prominent hill ranges, such as the Western Ghats and the Satpura Range.
Therefore, statement 2 is incorrect.
Statement 3: The river valleys in the Peninsular region are deep with high gradients.
The Peninsular region of India is characterized by its ancient, stable, and highly eroded landscape. The region is crisscrossed by numerous rivers, which have carved deep and steep valleys over millions of years.
The river valleys in the Peninsular region are indeed deep and have high gradients. The rivers, such as the Godavari, Krishna, and Kaveri, have cut through the hard basaltic lava flows and have created deep gorges and canyons. These river valleys are an important feature of the Peninsular region's topography.
Therefore, statement 3 is correct.
In conclusion, statement 1 and statement 3 are correct, while statement 2 is incorrect. Therefore, the correct answer is option 'A' (1 and 2 only).
