Which mountain range marks the boundary between the Indo-Gangetic plain and the Deccan Plateau, running east-west across central India?

💡 Solution & Explanation

The Vindhya Range forms an essential physical barrier running west-east across central India, historically serving as the geographical boundary separating the fertile Indo-Gangetic plains from the plateau terrain of the Deccan. The Western Ghats run parallel along the western coast of the peninsula, while the Aravallis represent an ancient fold mountain chain in northwestern India. Physical geography modules highlight the Vindhyas as a major watershed dividing northern and southern river systems.
