Which lake in India was formed by a meteorite impact?

Last Updated:

This question examines an important river-or-lake fact: “Which lake in India was formed by a meteorite impact?” The correct answer is Lonar Lake. Lonar Lake (Lonar Crater Lake) in Buldhana district of Maharashtra was formed by a meteorite impact approximately 50,000 years ago. It is the largest hyper-velocity impact crater in basaltic rock in the world. The lake has both saline and freshwater zones. Lakes may be tectonic, glacial, volcanic, fluvial, coastal, artificial or formed by landslides. They may contain fresh, brackish or saline water, so terms such as lake, lagoon, reservoir and wetland should not be used interchangeably.

Correct Answer: Lonar LakeYour Answer: B

Explanation

Option A (“Dal Lake”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option C (“Wular Lake”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option D (“Chilika Lake”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Similar names may belong to another tributary, lake class, state or project. Therefore the correct option, index and explanation consistently identify Lonar Lake. Lonar Lake (Lonar Crater Lake) in Buldhana district of Maharashtra was formed by a meteorite impact approximately 50,000 years ago. It is the largest hyper-velocity impact crater in basaltic rock in the world. The lake has both saline and freshwater zones.
