– The unique alkaline and saline nature of the lake water also contributes to its unusual ecosystem.
– Pangong Lake is known for its changing colours and is a high-altitude lake.
– Chilika Lake is India’s largest coastal lagoon, known for its biodiversity and migratory birds.
– Loktak Lake in Manipur is famous for its floating islands (phumdis) and Keibul Lamjao National Park.

The correct answer is A) A-3, B-1, C-2, D-4.
– Bhimtal is a lake in the Nainital district of Uttarakhand. Many lakes in this region, including Bhimtal, are believed to be formed by tectonic activity (faulting and subsidence). Thus, A-3 (Tectonic).
– Ashtamudi Lake is a large backwater lake in Kerala, forming part of the Ashtamudi Wetland Ramsar site. Backwater lakes are a type of lagoon. Thus, B-1 (Lagoon).
– Gohna Lake in Uttarakhand was formed in 1894 when a massive landslide blocked the Birahi Ganga river, creating a natural dam. Thus, C-2 (Landslide).
– Lonar Lake in Maharashtra is a saline soda lake believed to have been formed by a meteorite impact during the Pleistocene epoch. This makes it a crater lake (specifically, an impact crater lake). Thus, D-4 (Crater).
Lakes are formed by various geological and geomorphological processes, including tectonic activity, volcanic activity (crater lakes), erosion and deposition by glaciers (glacial lakes), rivers (oxbow lakes, floodplain lakes), wind (playas), dissolution of soluble rocks (karst lakes), landslides, and meteorite impacts. Lagoons are typically coastal features separated from the sea by a barrier.
