1. The Southern plateau block is formed mainly of granite and gneiss: This statement is correct. The Peninsular Plateau, particularly the southern part, is composed of ancient crystalline igneous and metamorphic rocks like granite and gneiss, which are part of the stable continental shield.
2. The Deccan lava plateau is an elevated tableland consisting of horizontally arranged lava sheets: This statement is correct. The Deccan Traps region, covering a large part of the Peninsular Plateau, was formed by massive volcanic eruptions, resulting in layers of basaltic lava flows that solidified to form a high, flat plateau.
3. The Malwa plateau dominates the Vindhyan scraps, forming the Eastern flank of the plateau: This statement is incorrect. The Malwa Plateau is located to the north of the Vindhyan Range, with the Vindhyan scarp forming its southern boundary. It does not dominate the Vindhyan scraps, and the Vindhyan scarp forms the southern boundary of the plateau, not the eastern flank. The eastern part of the Malwa plateau slopes towards the Chambal river system.
4. The trough of the Narmada and Tapti is interposed between the Vindhyan and the Satpura ranges: This statement is correct. The Narmada River flows through a rift valley (trough) situated between the Vindhya Range to the north and the Satpura Range to the south. The Tapti River flows through another rift valley south of the Satpura Range. The combined river valleys are located between the two prominent hill ranges.
Based on the analysis, statements 1, 2, and 4 are correct.
Understand the geological composition and structure of the Peninsular Plateau, including the location of major physiographic divisions like the Deccan Plateau, Malwa Plateau, Vindhya Range, Satpura Range, and major river valleys like Narmada and Tapti.
The Peninsular Plateau is one of the oldest landmasses on Earth. It is a stable block composed of crystalline rocks. It is broadly divided into two parts by the Narmada valley: the Central Highlands (including Malwa Plateau) and the Deccan Plateau. The Western and Eastern Ghats form the western and eastern edges of the Deccan Plateau, respectively.
