Plate Tectonics and the movement of the Indian plate

प्लेट विवर्तनिकी और भारतीय प्लेट की गति

In this Class 11 Geography topic from “Distribution of Oceans and Continents,” students learn how plate tectonics explains the changing arrangement of continents and ocean basins. They study the structure and movement of lithospheric plates, the major types of plate boundaries, and the forces linked to their motion. The topic traces the Indian plate’s journey from Gondwana, its northward movement, and its collision with the Eurasian plate, connecting these processes with the formation of the Himalayas, earthquakes, and volcanism.
