The extinction of dinosaurs happened about 66 million years ago at the end of the Cretaceous period.
Most scientists believe a giant asteroid impact (Chicxulub crater, Mexico) caused massive fires, dust clouds, and climate change, blocking sunlight and collapsing food chains — leading to the extinction of about 75% of Earth’s species.

Lonar Lake is a unique crater lake in Maharashtra, India, formed about 50,000 years ago by a meteorite impact.
It is the only hypervelocity impact crater in basalt rock and has saline, alkaline water with rare microorganisms. 🌍

🪨 Sailing Stones (Short Note)
Sailing stones are rocks that move on their own across the dry lake bed of Racetrack Playa, Death Valley (USA).
They leave long tracks behind them.
🔎 Movement occurs when:
Rain creates a thin water layer
Water freezes at night
Wind pushes thin ice sheets
Ice slowly moves the rocks
This natural phenomenon was confirmed in 2014.

🐍 Vasuki indicus (Short Note)
Vasuki indicus is an extinct giant snake discovered in India.
📍 Found in Gujarat
📅 Lived ~47 million years ago (Eocene)
📏 Estimated length: 10–15 meters
🦴 Belongs to the Madtsoiidae family
It is one of the largest snakes ever discovered.

❄️ Gas Hydrate (Short Note)
Gas hydrate is an ice-like solid where methane gas is trapped inside water crystals under:
Low temperature
High pressure
📍 Found in deep ocean sediments and Arctic regions.
🔥 Called “burning ice” because it looks like ice but can burn.
⚡ Important as a potential future energy source and for climate studies.

🔥 Darvaza Gas Crater
(“Door to Hell”)
The Door to Hell is a massive, continuously burning natural gas crater located in the Karakum Desert of Turkmenistan. It is one of the most dramatic human-made geological phenomena on Earth.
