Indo-Ganga-Brahmaputra Plain
The third geological division of India consists the plains formed by the rivers Indus, Ganga, and Brahmaputra. Initially, it was a geo-synclinal depression that reached its peak development during the third phase of Himalayan mountain formation around 64 million years ago. Since then, it has gradually been filled by sediments carried by the Himalayan and Peninsular rivers. The average depth of alluvial deposits in these plains ranges from 1,000 to 2,000 meters. The relief and physiography of India have been significantly shaped by the geological and geomorphological processes active in the Indian subcontinent.
Structure and Physiography| Chapter 2 Class 11 Geography Notes
Class 11 Geography Ch 2 Structure and Physiography Notes: In Class 11 Geography Chapter 2, we learn about the different shapes and features of the Earth’s surface. This includes things like mountains, plateaus, plains, and valleys. We examine how these features are formed over a long time by various natural processes like movement of the Earth’s crust, erosion, and deposition. By studying this chapter, we get to understand more about how the Earth’s surface changes and how it’s connected to geological processes.
The Structure and Physiography notes cover all the necessary topics that are extremely important for the examination 2024. It can save you time and will positively affect your results.
