Correct Option
The correct option isWular Lake
Explanation
Lakes in India are formed through various geological and geomorphological processes, including glacial action, wind, river meandering, and tectonic activity. Tectonic lakes are formed due to the movements of the Earth's crust, which create depressions that subsequently fill with water.
Detailed Analysis
- Wular Lake: Located in the Bandipora district of Jammu and Kashmir, Wular Lake is the result of tectonic activity. The tectonic movements created a basin which was later filled by the waters of the Jhelum River. It is recognized as the largest freshwater lake in India.
- Dal Lake: Also located in Srinagar (Kashmir), it is a freshwater lake often associated with glacial and fluvial action (remnants of oxbows), but Wular is the primary example of tectonic origin in this region.
- Bhimtal: Located in the Nainital district of Uttarakhand, this is a C-shaped lake. While the Kumaon lakes have complex origins involving tectonic and landslide damming, Wular is the standard textbook example for a tectonic depression.
- Loktak Lake: Located in Manipur, it is famous for its floating phumdis (heterogeneous mass of vegetation, soil, and organic matter) and is not primarily categorized as a tectonic depression in the same context as Wular.
Key Takeaway: Wular Lake (Jammu & Kashmir) is the largest freshwater lake in India and is distinctively formed due to tectonic activity.
