Lakes

झीलें

In Class 9 Geography, the topic “Lakes” explains how these water bodies form part of the drainage system and differ from rivers in their shape, movement, and location. Students learn about natural lakes formed by tectonic activity, glaciers, river courses, and coastal processes, as well as human-made reservoirs. Indian examples such as Wular, Dal, Sambhar, Chilika, and Kolleru help connect ideas with maps and landscapes. The topic also examines how lakes store water, support irrigation, hydropower, fisheries, biodiversity, tourism, and flood regulation.
