Statement 1: Lonar Lake is a notified National Geo-Heritage Monument.
- This statement is correct. Lonar Lake is indeed a notified National Geo-Heritage Monument.
- Lonar Lake is a unique and ancient crater lake located in the Buldhana district of Maharashtra, India.
- It was formed around 50,000 years ago when a meteorite hit the Earth's surface, creating a circular crater with a diameter of about 1.8 kilometers.
- The lake and its surrounding area have significant geological and ecological importance, which led to its recognition as a National Geo-Heritage Monument.

- The lake is situated inside the Deccan Plateau, which is a large plateau in central India.
- However, Lonar Lake is alkaline or basic in nature, with a pH level of around 10-11.5.
- The alkalinity of the lake is primarily due to the presence of various salts and minerals dissolved in its water, such as sodium, magnesium, and potassium.
