Role of Rivers

नदियों की भूमिका

In Class 9 Geography, this topic from the chapter “Drainage” explains how rivers shape the land through erosion, transportation and deposition. Students learn how river systems and drainage patterns influence plains, valleys, agriculture, settlements, transport and the availability of water. The topic also highlights the importance of rivers in human life, along with challenges such as pollution, floods and the need for careful conservation and management of river resources.
